    State of New Jersey v. Kingkamau Nantambu (A-97-13) (073589)
    Argued February 2, 2015 -- Decided April 29, 2015
    SOLOMON, J., writing for a unanimous Court.
    In this interlocutory appeal, the Court addressed the admissibility of a recorded conversation where a
    portion of the conversation was inadvertently omitted from the recording.
    Atlantic City police responded to reports of a domestic disturbance between defendant Kingkamau
    Nantambu and his girlfriend, Crystal Aikens. Aikens told police that defendant had threatened her with a gun. After
    police located a hidden handgun in defendant’s apartment, defendant was charged with fourth-degree possession of
    a defaced firearm and second-degree possession of a weapon by a convicted person.
    Subsequently, Aikens called the Atlantic County Prosecutor’s Office alleging that defendant had engaged
    in witness tampering. She agreed to call defendant on her cell phone and allow Detectives Ted DeSantis and Rich
    Johannessen to record the conversation. Johannessen attached two earpieces to a digital audio recorder so that the
    device could record the conversation while the detectives listened in. Aikens also used the “speaker phone” function
    so the detectives could hear without headphones. During the conversation, defendant asked Aikens if she had been
    to the Prosecutor’s Office. She replied that she had stalled them, and asked defendant for the money he had
    promised her. Defendant, agreeing that he had promised her money, advised Aikens as to what to say when she was
    questioned. During a discussion about the gun, defendant insisted that “[n]obody seen the gun that day.” Aikens
    disagreed, claiming that she saw defendant put the gun in a case. Immediately after that statement, a beeping sound
    interrupted the conversation. According to Johannessen, Aikens had moved the phone, causing the recording device
    to fall and the wires to disconnect. Johannessen picked up the recorder, removed and replaced its batteries, and
    replaced the wires. By the time recording resumed, approximately two minutes had passed and Aikens and
    defendant were concluding their conversation. Based on the conversation, charges of third-degree bribery of a
    witness, third-degree witness tampering, and fourth-degree tampering with physical evidence were added to
    defendant’s existing weapons charges.
    The recording was offered as evidence demonstrating defendant’s intent to tamper with the State’s witness
    and showing that defendant possessed the gun for which he was charged with unlawful possession. Defendant
    moved to suppress the recording, asserting that the two-minute gap rendered it inadmissible. At the suppression
    hearing, DeSantis explained that the detectives heard the unrecorded portion of the conversation, during which he
    claimed nothing relevant was said. Although Johannessen stated that he only could hear Aikens’ side of the
    discussion, he concurred that nothing was said relating to the recorded portion of the conversation.
    The trial court, relying State v. Driver, 
    38 N.J. 255
     (1962), granted defendant’s motion, finding that the
    two-minute gap rendered the recording inadmissible as substantive evidence. The court determined that it was
    irrelevant whether the deletion was intentional. Rather, it only mattered that the recording was interrupted following
    a very damaging statement regarding defendant’s alleged possession of the gun. On reconsideration, the judge noted
    that flawed recordings may be admitted, but fundamental fairness required exclusion of this recording because the
    interruption occurred at a particularly crucial point.
    The Appellate Division granted the State’s motion for leave to appeal, and reversed in an unpublished
    decision. Since the detectives asserted that nothing important was said during the two-minute gap, the panel rejected
    the trial court’s conclusion that the conversation was interrupted at a critical point. It concluded that the omitted
    portion went to the weight and probative value of the evidence rather than its admissibility. The Court granted
    defendant’s petition for certification. 
    217 N.J. 623
     (2013).
    HELD: When considering the admissibility of a recording containing a partial omission, the trial court must
    employ a two-part analysis. First, the trial court must determine if the omission is unduly prejudicial, conducting an
    objective analysis focused on the evidentiary purposes for which the recording is being offered. If the trial court, in
    its discretion, finds the omission unduly prejudicial, it must then consider whether it renders all or only some of the
    recording untrustworthy, and suppress only that portion deemed untrustworthy.
    1. Relevant evidence is admissible under N.J.R.E. 402 unless “its probative value is substantially outweighed by the
    risk of undue prejudice.” N.J.R.E. 403. Determinations on the admissibility of evidence are generally made outside
    the presence of the jury in a Rule 104 hearing. A trial court’s evidentiary rulings are reviewed for abuse of
    discretion, but no deference is accorded to the court’s legal conclusions. (pp. 13-14)
    2. In State v. Driver, 
    38 N.J. 255
     (1962), this Court set forth the standard for the admissibility of a recording in a
    criminal trial, requiring analysis of whether: (1) the device could record the conversation or statement; (2) its
    operation was competent; (3) the recording was authentic and correct; (4) no changes, deletions or additions were
    made; and (5) any alleged confessions were elicited voluntarily. The second and fourth Driver factors are at issue
    here. No prior case law exists in which this Court has defined what was meant by operator competence or parsed
    the effect of an unintentional omission. Since determining whether the recording should have been excluded calls
    for an application of the law to the facts, the Court reviews the trial court’s decision de novo. (pp. 14-16)
    3. The second and fourth Driver factors are safeguards designed to ensure the trustworthiness of a recording. In
    State v. Cusmano, 
    274 N.J. Super. 496
     (App. Div. 1994), the Appellate Division examined the operator-competence
    factor and concluded that trustworthiness is the polestar for the admissibility of a recording. Applying New Jersey
    jurisprudence since Driver and federal decisional law considering the admissibility of incomplete recordings, the
    panel held that determinations of operator competence must be viewed liberally. The Court agrees with this
    conclusion, finding that courts should focus on the reliability of the recording rather than the actions or
    qualifications of the operator. In light of technological advances since Driver, which have made recording devices
    more reliable and easy to use, the operator competency factor no longer requires separate consideration. (pp. 16-18)
    4. Turning to the fourth Driver factor, pursuant to the established standards governing the admissibility of
    recordings, the Court finds no basis to conclude that the exclusion of a recording in its entirety is required merely
    because an omission rendered a portion of the recording unduly prejudicial. Rather, in such circumstances a trial
    court should conduct a Rule 104 hearing to determine whether the omission renders all or part of the recording
    unreliable and inadmissible. The recording should be admitted to the extent that it contains competent and relevant
    evidence, while the portion deemed unduly prejudicial should be redacted. (pp. 18-19)
    5. Here, the Court finds no basis to disturb the trial court’s finding that the omission of defendants’ response to
    Aikens’ accusatory statement was unduly prejudicial to defendant. Turning to the question of whether the defect
    requires exclusion, the Court reiterates that this decision is entrusted to the trial court’s discretion, which must take
    into account the evidential purpose served by the recording, including considering whether the recording is
    probative of one or multiple theories of the case. Where, as here, the recording contains competent relevant
    evidence relating to two distinguishable evidentiary purposes, the question becomes whether the recording must be
    precluded in its entirety. Relying on N.J.R.E. 105 and the Appellate Division’s persuasive reasoning in State v.
    Zicarelli, 
    122 N.J. Super. 225
     (App. Div. 1973), the Court concludes that redaction is appropriate in such
    circumstances. Here, although the omission renders a portion of the conversation unduly prejudicial with respect to
    the weapons charge, nothing in the record suggests that the omission created a risk of undue prejudice with respect
    to the bribery and witness-tampering charges. Thus, according appropriate deference to the trial court’s findings, the
    Court holds that the recording was admissible up to and including the point at which defendant stated “[n]obody
    seen the gun that day.” (pp. 19-25)
    6. Where a recording contains a partial omission, trial courts must determine whether the omission is unduly
    prejudicial and, if so, whether the omission renders all or only some of the recording inadmissible. Although the
    Driver analysis remains relevant to these determinations, a recording’s shortcomings with respect to one factor do
    not automatically necessitate exclusion of the entire recording. Rather, the court should consider the Driver factors
    together, on a case-by-case basis, to determine whether and to what extent a recording contains competent relevant
    evidence. (pp. 26-27)
    The judgment of the Appellate Division is REVERSED, and the matter is REMANDED to the trial court
    for proceedings consistent with this opinion.
    CHIEF JUSTICE RABNER; JUSTICES LaVECCHIA, ALBIN, PATTERSON, and FERNANDEZ-
    VINA; and JUDGE CUFF (temporarily assigned) join in JUSTICE SOLOMON’s opinion.

    SUPREME COURT OF NEW JERSEY
    A-97 September Term 2013
    073589
    STATE OF NEW JERSEY,
    Plaintiff-Respondent,
    v.
    KINGKAMAU NANTAMBU,
    Defendant-Appellant.
    Argued February 2, 2015 – Decided April 29, 2015
    On certification to the Superior Court,
    Appellate Division.
    Joseph C. Liguori argued the cause for
    appellant (Mazraani & Liguori, attorneys).
    Deborah C. Bartolomey, Deputy Attorney
    General, argued the cause for respondent
    (John J. Hoffman, Acting Attorney General of
    New Jersey, attorney).
    JUSTICE SOLOMON delivered the opinion of the Court.
    In this interlocutory appeal, we address the admissibility
    of a recorded conversation where a portion of the conversation
    was inadvertently omitted from the recording.    The recording in
    question is a phone conversation between defendant Kingkamau
    Nantambu and his girlfriend, Crystal Aikens.    It was made during
    a police investigation into allegations by Aikens that defendant
    had engaged in witness tampering related to a prior indictment
    for weapons offenses.   The recording was interrupted when the
    1
    recording device fell to the ground, causing the wires to
    disconnect and the device to shut off.    Critically, the
    recording stopped directly after Aikens stated that she had seen
    defendant with the gun that formed the basis of the weapons
    charges against him; defendant’s response, if any, was not
    recorded.
    The question presented is whether an inadvertent omission
    that renders a portion of a recording unreliable requires
    suppression of the entire recording.     Having carefully reviewed
    the evidentiary concerns animating our decision in State v.
    Driver, 
    38 N.J. 255
     (1962), and accounting for the technological
    advances that have taken place over the past half century since
    that decision, we take this opportunity to emphasize that
    reliability is the decisive factor in determining the
    admissibility of a recording.   A review of Driver and its
    progeny indicates that the decision whether to admit a recording
    into evidence is a highly fact-sensitive analysis, requiring
    consideration not only of any gaps or defects in the recording
    but also the evidential purposes for which the recording is
    being offered.   Nothing in our review of case law or evidentiary
    rules requires suppression of an entire recording when only part
    of that recording has been omitted or is found unreliable.
    Instead, the trial court should conduct an N.J.R.E. 104 hearing
    to evaluate which portions of a recording are reliable, and
    2
    which portions must be redacted.       The trial court should admit
    the recording to the extent it is deemed reliable, redacting
    only the portion of the recording deemed unreliable due to an
    omission or defect.    We therefore vacate the Appellate
    Division’s order, which admitted the recording in its entirety,
    and remand for further proceedings.
    I.
    The following facts are derived from the evidentiary
    hearings held in response to defendant’s pretrial motions.
    Atlantic City Police Detective David Smith responded to reports
    of a domestic disturbance at defendant’s residence.      Aikens
    greeted Detective Smith outside defendant’s apartment and told
    him that defendant had threatened her with a gun.      Detective
    Smith arrested defendant and transported him to the police
    station.
    En route to the police station, defendant consented to a
    search of his apartment.   Detective Smith returned to the
    apartment and, after a brief search, found a handgun hidden
    under a child’s bed.   Defendant was subsequently charged with
    fourth-degree possession of a defaced firearm, N.J.S.A. 2C:39-
    3
    3(d), and second-degree possession of a weapon by a convicted
    person, N.J.S.A. 2C:39-7.1
    After defendant filed an unsuccessful motion to suppress
    the gun, Aikens left a voice mail with the Atlantic County
    Prosecutor’s Office indicating that defendant had engaged in
    witness tampering.   The next day, Aikens met with Detectives Ted
    DeSantis and Rich Johannessen at the Prosecutor’s Office.    At
    the detectives’ request, Aikens agreed to call defendant on her
    cell phone and to allow the detectives to record the
    conversation, a process commonly referred to as a “consensual
    intercept.”2   To facilitate better cell phone reception and to
    avoid background noise that might indicate to defendant that
    Aikens was at the Prosecutor’s Office, the call was conducted in
    the parking lot behind the Prosecutor’s Office.
    Detective Johannessen attached two earpieces to a digital
    audio recorder, which allowed the recording device to record the
    conversation while the detectives simultaneously listened to the
    1The indictment also charged defendant with possession of a weapon
    for an unlawful purpose, N.J.S.A. 2C:39-5(d).     That charge was
    omitted from the superseding indictment, discussed infra.
    2 Consensual intercepts are governed by the New Jersey
    Wiretapping and Electronic Surveillance Control Act, N.J.S.A.
    2A:156A-1 to -34, which sets forth a variety of protocols. We
    have held that the statute “demands strict adherence to its
    protocols.” State v. K.W., 
    214 N.J. 499
    , 503 (2013). No
    argument was raised regarding adherence to the statute’s
    requirements.

    conversation using headphones.     The detectives also directed
    Aikens to use the cell phone’s “speaker phone” function, which
    allowed them to overhear the conversation without the
    headphones.
    During the conversation, defendant asked Aikens if she had
    gone to the Prosecutor’s Office.       Aikens replied that she had
    “stalled” the Prosecutor’s Office by telling them she would
    “come next week.”   She and defendant then had the following
    discussion:
    [Aikens]: [Y]ou said yesterday you were
    going to give me some money.
    [Defendant]: What happen?
    [Aikens]: You said yesterday you was going
    to give me some money, [b]out when I come
    from the Prosecutor’s office.
    [Defendant]: I got you. . . . I told you
    yesterday.
    . . . .
    [Aikens]: Am I going to have to go to trial
    too? Cause they didn’t send me no subpoena
    or nothing.
    [Defendant]: Now another thing my lawyer
    was saying, was . . . if you let the
    prosecution know in advance that your
    statement is going to be that it wasn’t his
    gun I don’t know who[se] gun it was. Then
    there’s nothing they can do as far as
    charging anybody. You know what I am
    saying?
    [Aikens]: I did not tell them, I ain’t tell
    them I put the gun nowhere.
    5
    After defendant assured Aikens that he would get her money,
    Aikens stated that she was concerned that she might “get in
    trouble,” and that she was “really stressed out” about the
    situation.   Defendant responded that he had spoken with his
    lawyer, and that she would not “get in trouble . . . as long as
    you don’t say [the gun is] yours.”   The following exchange
    ensued.
    [Defendant]: They can’t charge you with
    nothing.
    [Aikens]: As long as I don’t say it’s mine?
    [Defendant]: Yeah, you go in there and say
    oh yeah, it’s my gun, then they going to
    charge you . . . .
    [Aikens]: Why the hell would I say it was
    mine?
    [Defendant]: It’s just a h[y]pothetical. We
    ain’t saying that you are going to say that
    shit. But what I am saying is that is the
    only way they would be able to charge you
    with anything. . . . He said they can’t
    charge you with perjury because you never
    made an official statement.
    . . . .
    [Defendant]: You didn’t see the gun that
    day.
    [Aikens]: Huh?
    . . . .
    [Aikens]: You said I didn’t see it that day?
    [Defendant]: Nobody seen the gun that day.
    6
    [Aikens]: Yes I did. I saw you putting it in
    the case when we was arguing in the room. I
    did. And Keisha heard us in there arguing.
    Immediately after Aikens stated that she saw defendant with
    the gun, a beeping sound interrupted the conversation.
    Detective Johannessen asked whether the recorder’s battery had
    died.   Aikens indicated that she received an incoming call from
    a friend, told her friend that she would call her back, and
    resumed the conversation with defendant.    However, according to
    Detective Johannessen at that moment Aikens moved the phone and
    “pulled the wires down,” causing the recording device to fall
    and the wires to disconnect from the cell phone.    Detective
    Johannessen picked up the recorder, noticed that it appeared
    “dead,” removed and replaced the battery, and replaced the wires
    for the earpieces.    By the time recording resumed, approximately
    two minutes had passed and Aikens and defendant were concluding
    their conversation.
    Aikens also provided the detectives with text messages sent
    by defendant to Aikens over a four-day period.   In those text
    messages, defendant asked, “Do you prefer the Wii or the cash?”;
    and stated, “My lawyer said he’s going to call you in a bit, . .
    . I really need you to help me out here.”
    Based on defendant’s communications with Aikens, an
    Atlantic County Grand Jury returned a superseding indictment
    7
    charging defendant with third-degree bribery of a witness,
    N.J.S.A. 2C:28-5(d); third-degree witness tampering, N.J.S.A.
    2C:28-5(a); and fourth-degree tampering with physical evidence,
    N.J.S.A. 2C:28-6(1); in addition to the weapons offenses.
    Defendant moved to suppress the recording, asserting among
    other arguments that the two-minute gap rendered the recording
    inadmissible.   At the suppression hearing, the prosecutor argued
    that the recording, considered together with defendant’s text
    messages to Aikens, was relevant to show that defendant offered
    Aikens either a video-game system or cash to change her
    testimony.   The assistant prosecutor also argued that defendant
    admitted in the recorded conversation to possessing the gun that
    formed the basis of the weapons charge against him.
    The prosecutor then presented the testimony of Detectives
    DeSantis and Johannessen.   Detective DeSantis stated that he had
    never conducted a consensual recording before, and that
    Detective Johannessen handled the technical aspects of the
    operation.   Johannessen confirmed that he managed the recording,
    including connecting the recorder to the phone and reconnecting
    the device after it fell.   Johannessen stated that he used the
    recording device “somewhat frequently,” and that before using it
    he “always check[s] it to make sure the battery[ is] fresh.
    Usually I’ll play it safe and put a fresh battery in each time.”
    Johannessen also stated that it took “approximately 15 or 20
    8
    seconds” to reconnect the device after it fell, and speculated
    that the recording did not resume for another minute and forty
    seconds because “the [digital audio] file wasn’t closed
    properly.”
    Detective DeSantis testified that, because the phone was
    “on speaker the entire time,” he could hear both sides of the
    conversation during the period the phone was disconnected from
    the recorder, and that “[a]s far as anything pertaining to our
    case, nothing was mentioned.”   Detective Johannessen similarly
    testified that, “to [his] recollection,” nothing was said in the
    unrecorded portion of the conversation that related to the
    recorded portion of the conversation.   However, at variance with
    DeSantis’s testimony, Johannessen stated that he was only able
    to hear Aikens’ side of the conversation after the recorder fell
    “because the cords were disconnected from the recorder.”
    The motion judge considered the factors for admissibility
    of a recording set forth in Driver, and determined that the two-
    minute gap rendered the recording inadmissible as substantive
    evidence and granted defendant’s motion.   The judge determined
    that it was irrelevant whether the deletion was intentional; it
    mattered only that the recording was interrupted just after
    Aikens made a “very damaging” statement regarding defendant’s
    possession of the gun, depriving the listener of an opportunity
    to hear defendant’s response.   The judge added that although he
    9
    was not making a finding that the detectives were incompetent,
    “[a] competent operator wouldn’t” have allowed the recorder to
    fall.
    At the hearing on the prosecutor’s motion for
    reconsideration, the judge acknowledged that recordings may be
    admitted even when there are gaps in the recording.   He
    nevertheless determined that the recording was inadmissible
    because the recording stopped “at a particularly crucial point
    of that conversation,” when Aikens stated that she saw defendant
    with the gun.3   The judge affirmed his previous order, concluding
    that the recording did not include “substantially all” of the
    pertinent conversation and therefore is inadmissible as a matter
    of “fundamental fairness.”
    The Appellate Division granted the State’s motion for leave
    to appeal, and reversed in an unpublished decision.   The panel,
    noting that the trial judge did not find the omission in the
    recording was the result of intentional misconduct,
    3 The judge was also concerned that admitting Aikens’ accusation
    “with absolutely no response from [defendant]” would require
    defendant to “give up his Fifth Amendment rights” because his
    only opportunity to respond would be “to get on the stand and
    say this is what I would have said.” Defendant does not raise
    this argument and, given our resolution of this matter, we need
    not address its applicability here. See In re Civil Commitment
    of D.Y., 
    218 N.J. 359
    , 379 (2014) (“As a general principle, ‘we
    strive to avoid reaching constitutional questions unless
    required to do so.’” (quoting Comm. to Recall Menendez v. Wells,
    
    204 N.J. 79
    , 95 (2010))).
    10
    characterized the question presented as “whether an inadvertent
    failure to record one portion of a conversation justifies the
    exclusion of the entire tape.”     The panel, relying on State v.
    Dye, 
    60 N.J. 518
    , 531, cert. denied, 
    409 U.S. 1090
    , 
    93 S. Ct. 699
    , 
    34 L. Ed. 2d 675
     (1972), and State v. Cusmano, 
    274 N.J. Super. 496
     (App. Div. 1994), determined that the recording
    should be admitted.   The panel explained:
    [T]he only types of deletions, omissions,
    gaps, and unintelligible or inaudible parts
    in the recording of a conversation that will
    warrant the recording’s exclusion from
    evidence are those that raise the questions
    concerning whether the recording is a
    trustworthy record of statements actually
    uttered during a conversation by the parties
    to it.
    Citing the detectives’ testimony that nothing important was
    said during the unrecorded portion of the conversation, the
    panel rejected the motion judge’s finding that the conversation
    was cut off at a critical point.      The panel concluded that the
    omitted portion goes to the weight and probative value of the
    evidence rather than its admissibility.
    We granted defendant’s petition for certification.       State
    v. Nantambu, 
    217 N.J. 623
     (2013).
    II.
    Defendant maintains that the recording should be suppressed
    because two factors of the test set forth in Driver, 
    supra,
     
    38 N.J. at 287
    , were not met, namely: (1) the operators were not
    11
    competent, and (2) the recording contained omissions.    He argues
    that the detectives operating the recorder were not competent
    because they chose to conduct the recording “outside in a non-
    secure area.”   That decision, defendant contends, led to an
    interruption in the recording at “the most important aspect of
    the conversation.”
    Defendant asserts that the recording was interrupted at a
    critical point in the conversation because the recording stopped
    just after Aikens stated that she saw defendant with the gun on
    the day of his arrest.   Defendant argues that Aikens’ statement
    was clearly designed to elicit an admission from him that the
    gun was his, and that the omission of his response renders the
    recording unduly prejudicial because it asks the jury to
    speculate as to what, if any, reply he gave.    Defendant further
    notes that the omission relates to the most serious offense with
    which he has been charged.
    The State responds that the existence of an audible
    recording alone establishes the competency of both the operators
    and the recording device.    The State argues that the
    unintentional omission of a “small segment” of an eighteen-
    minute conversation does not render the entire recording
    inadmissible under Driver.   The State echoes the appellate
    panel’s conclusion that, unless the recording was rendered
    untrustworthy by the omission, the recording should be deemed
    12
    admissible.    The State adds that suppression of the entire
    recording was an abuse of discretion because it deprived the
    jury of the most reliable proof available.
    Put succinctly, the issue before this Court is whether an
    omission rendering only a portion of a recording untrustworthy
    requires exclusion of the entire recording.     Whether the
    recording in this case is admissible requires this Court to
    refine the meaning and application of two factors from the
    Driver test: operator competency and omission from the recorded
    conversation.
    III.
    We begin by acknowledging fundamental evidentiary
    principles.     “Once evidence is deemed relevant, it is
    admissible, N.J.R.E. 402, unless ‘its probative value is
    substantially outweighed by the risk of [] undue prejudice,’
    N.J.R.E. 403, or some other bar to its admission is properly
    interposed.”    Brenman v. Demello, 
    191 N.J. 18
    , 34-35 (2007)
    (alteration in original).     This determination is generally made
    outside the presence of the jury in a N.J.R.E. 104 hearing.
    See, e.g., State v. Wakefield, 
    190 N.J. 397
    , 482 (2007), cert.
    denied, 
    552 U.S. 1146
    , 
    128 S. Ct. 1074
    , 
    169 L. Ed. 2d 817
    (2008); State v. Collier,

    , 196 (App. Div.
    1998), certif. denied, 
    158 N.J. 71
     (1999).     The trial judge has
    broad discretion to exclude evidence as unduly prejudicial
    13
    pursuant to N.J.R.E. 403.   See State v. Nelson, 
    173 N.J. 417
    ,
    470 (2002); State v. Swint, 
    328 N.J. Super. 236
    , 253 (App.
    Div.), certif. denied, 
    165 N.J. 492
     (2000).
    “‘[A] trial court’s evidentiary rulings are entitled to
    deference absent a showing of an abuse of discretion, i.e.,
    there has been a clear error of judgment.’”     State v. Harris,
    
    209 N.J. 431
    , 439 (2012) (alteration in original) (quoting State
    v. Brown, 
    170 N.J. 138
    , 147 (2000)).   However, we accord no
    deference to the trial court’s legal conclusions.    See, e.g.,
    State v. Mann, 
    203 N.J. 328
    , 337 (2010).     Thus, we uphold the
    facts found by the motion judge to the extent they are supported
    by sufficient credible evidence in the record, but “apply the
    law as [we] understand[] it” to those facts.     Ibid.; State v.
    Harris,

    , 415 (2004), cert. denied,

    IV.
    A.
    With these standards in mind, we briefly review the state
    of the law on admissibility of incomplete recordings.    This
    Court in Driver, 
    supra,
     set forth the standard for the
    admissibility of a recording in a criminal trial:
    [T]he speakers should be identified and it
    should be shown that (1) the device was
    capable of taking the conversation or
    statement, (2) its operator was competent,
    (3) the recording is authentic and correct,
    14
    (4) no changes, additions or deletions have
    been made, and (5) in instances of alleged
    confessions, that the statements were
    elicited voluntarily and without any
    inducement.
    [
    38 N.J. at 287
    .]
    In Driver, we considered the admission of a taped recording
    of the defendant’s statement to the police that was so “garbled”
    and “full of static and other foreign sounds” that “it was
    unintelligible and inaudible for the most part.”      
    Id. at 288
    .
    Indeed, the trial judge acknowledged the recording was
    inaudible, but admitted it nonetheless.      
    Ibid.
       We noted that,
    in most situations, an audio recording “may be an invaluable
    aid,” and “may be more satisfactory and persuasive evidence than
    [a] written and signed document.”    
    Id. at 287
    .     Thus, even a
    flawed audio recording is “not inadmissible per se, so long as
    its capacity to record accurately, and the other conditions
    precedent [are] established.”   
    Id. at 288
    .    Nevertheless, the
    audio recording in that case was so unintelligible that “[b]asic
    fairness demanded its exclusion.”    
    Ibid.
    Driver did not, however, elaborate on the two factors at
    issue in this appeal -- factor two, relating to the operator’s
    competence, and factor four, whether the recording contained
    changes or deletions.   Specifically, this Court has neither
    defined what was meant by operator competence nor parsed the
    effect of an unintentional omission or deletion.
    15
    B.
    Both the motion judge and the Appellate Division understood
    the standards governing the admission of an audio recording to
    require an absolute conclusion: either the recording contains an
    omission that is unduly prejudicial to defendant and therefore
    the recording must be excluded in its entirety, or the omission
    in the recording is not unduly prejudicial and must be admitted
    in its entirety.   As stated above, the motion judge determined
    that the omission, though inadvertent, was unduly prejudicial
    and ruled the recording inadmissible.   The appellate panel, for
    its part, disagreed that the omission was prejudicial and held
    that the recording should have been admitted.    As an application
    of law to the facts, we review this determination de novo.    See
    State v. Brown, 
    216 N.J. 508
    , 545 (2014) (“When a case involves
    mixed questions of law and fact, the Court provides deference to
    the supported factual findings of the trial court, but reviews
    de novo the application of legal principles to such factual
    findings.”).
    V.
    The second and fourth Driver factors disputed here are
    interrelated in that both are safeguards designed to ensure the
    trustworthiness of the recording.    The Appellate Division
    examined the operator-competence factor in Cusmano, 
    supra,
     and
    concluded that trustworthiness is the polestar for the
    16
    admissibility of a recording.    
    274 N.J. Super. at 514-17
    .     In
    that case, the motion judge determined that a ninety-minute
    recording of a taped conversation between the defendants and the
    witnesses to the crime, in which defendants attempted to
    persuade the witnesses not to testify, was inadmissible because
    the operator of the recording device was not competent and the
    recording contained omissions.    
    Id. at 498-99
    .   The panel,
    looking to New Jersey jurisprudence since Driver and federal
    decisional law considering the admissibility of incomplete
    recordings, held that “[a] determination of operator competence
    must be viewed liberally.”   
    Id. at 499-502, 509-12
    .
    The panel cited the Court of Appeals for the Eighth
    Circuit, stating that “‘[t]he fact that [the operator]
    successfully made the tape recordings [] satisfies the
    competency requirement.’”    
    Id. at 511
     (second alteration in
    original) (quoting United States v. Franklin, 
    747 F.2d 497
    , 498
    (8th Cir. 1984)); see also United States v. Hughes, 
    658 F.2d 317
    (5th Cir. 1981) (holding because “the paramount purpose of the
    inquiry is to insure the accuracy of the recording[,] . . . the
    government’s failure to show the competency of either the
    operator or the machine was overshadowed by the evidence which
    demonstrated the reliability of the tapes.” (citation omitted)),
    cert. denied, 
    455 U.S. 922
    , 
    102 S. Ct. 1280
    , 
    71 L. Ed. 2d 463
    (1982).   Thus, the panel determined that the question was not
    17
    whether, as the motion judge found, the operators “approached
    their responsibilities seriously” or “performed their task
    haphazardly,” but whether they “produce[d] substantially audible
    tape recordings of the telephone conversations with
    insignificant omissions.”    Cusmano, supra, 
    274 N.J. Super. at 513
    .
    We agree with Cusmano and the federal cases interpreting
    the operator-competency factor liberally, focusing on the
    reliability of the recording rather than the actions or
    qualifications of the operator.4      In light of technological
    advances in the forty years since Driver, which have made
    recording devices more compact, reliable, and easy to use, the
    second Driver factor -- the operator’s competence -- no longer
    requires separate consideration.
    Also, as in Cusmano, this case is distinguishable from
    Driver in that the momentary disruption in the recording did not
    create a “continuous audibility problem [that] rendered the
    4 In any event, unlike in Cusmano, the motion court here stopped
    short of finding the interruption in the recording was the
    result of operator incompetence. And properly so, as the record
    indicates the recording was interrupted not because of a
    technical mistake on the part of the operators but because
    Aikens unexpectedly pulled the connecting wires taut, causing
    the recorder to fall. Thus, even if the operators’ choices and
    qualifications were valid considerations, we would reject
    defendant’s suggestion that the detectives incompetently
    operated the recorder because they made the strategic choice to
    conduct the consensual intercept outside.
    18
    entire tape incomprehensible.”    
    Id. at 512-13
    .   Applying the
    established standards governing the admissibility of recordings,
    we find no basis to conclude that exclusion of a recording in
    its entirety is required merely because an omission rendered a
    portion of the recording unduly prejudicial.    Rather, we hold
    that a trial court should conduct a hearing pursuant to N.J.R.E.
    104 to determine, in his or her discretion, whether an omission
    or similar flaw in the recording renders all or part of that
    recording unreliable and therefore inadmissible as unduly
    prejudicial under N.J.R.E. 403.    The trial court should admit
    the recording to the extent that it contains competent and
    relevant evidence and redact the portion of the recording deemed
    unduly prejudicial.    The recording here, though incomplete, was
    entirely audible.     We turn then to the question of whether and
    to what extent the omission requires exclusion.     This inquiry
    proceeds in two parts.
    First, trial courts must determine in a N.J.R.E. 104
    hearing whether an omission renders a recording unduly
    prejudicial.   As Driver and its progeny make clear, the
    existence of an omission or defect in a recording does not
    automatically warrant suppression.     Rather, “if a tape is
    partially intelligible and has probative value, it is admissible
    even though substantial portions thereof are inaudible.”       State
    v. Zicarelli, 
    122 N.J. Super. 225
    , 239 (App. Div.), certif.
    19
    denied, 
    63 N.J. 252
    , cert. denied, 
    414 U.S. 875
    , 
    94 S. Ct. 71
    ,
    
    38 L. Ed. 2d 120
     (1973).
    Whether an omission renders a recording unduly prejudicial
    depends upon the extent to which the omission adversely affects
    the evidentiary purpose or purposes for which the recording has
    been offered.   Where, for example, the trial judge determines in
    his or her discretion that the omission reduces the probative
    value of the balance of the recording to such an extent that it
    is substantially outweighed by the risk of undue prejudice, then
    the recording should be excluded under N.J.R.E. 403.      See Dye,
    supra, 
    60 N.J. at 531
    ; Driver, 
    supra,
     
    38 N.J. at 288
    ; Cusmano,
    
    supra,
     
    274 N.J. Super. at 514-15
    .      The motion judge here
    determined that the omission of defendant’s response to Aikens’
    accusatory statement was unduly prejudicial to defendant.      We
    find no basis to disturb that finding.
    The Appellate Division rejected the motion judge’s finding
    that the gap in the recording was unduly prejudicial for three
    reasons.   First, the panel characterized as speculative the
    motion judge’s finding that the recording was cut off at a
    “crucial point.”   We disagree.   The recording cut out before
    defendant could respond to Aikens’ statement that she saw
    defendant “putting [the gun] in the case when we was arguing.”
    Defendant’s response to that accusatory statement was critical
    to assessing that statement’s probative value.
    20
    Second, the panel found that Detective DeSantis’ testimony
    that nothing of consequence was said during the unrecorded
    portion of the conversation “flatly contradicted” the motion
    judge’s finding.   However, Detective DeSantis testified that he
    was unable to recall what specifically was said after the
    recorder was disconnected and gave no indication what, if any,
    response defendant gave to Aikens’ accusatory statement.
    Further, Detective Johannessen testified that after the recorder
    became disconnected he was able to hear only Aikens’ side of the
    conversation.   Thus, despite his testimony to the contrary, he
    could not corroborate DeSantis’ assertion that nothing of
    consequence was said during the fifteen to twenty seconds it
    took to reconnect the recording device.
    Finally, the panel stated that defendant admitted in the
    recording to possessing the gun, which ameliorated any prejudice
    resulting from the gap in the recording.    However, at no point
    in the recorded conversation did defendant admit to possessing a
    gun; nor did he directly ask Aikens to claim that the gun was
    hers.   We therefore find the motion judge did not abuse his
    discretion in concluding that the omission of defendant’s
    response to Aikens’ accusatory statement casts serious doubts
    about the admissibility of the recording.
    We therefore proceed to the second part of the inquiry:
    whether the omission, if unduly prejudicial, requires
    21
    suppression of all or part of the recording.      We reaffirm that
    the question of whether a defect in a recording warrants
    exclusion is a matter entrusted to the trial judge’s discretion.
    Driver, supra, 
    38 N.J. at 288
    ; see also Daniel E. Feld,
    Annotation, Omission or Inaudibility of Portions of Sound
    Recording as Affecting its Admissibility in Evidence, 
    57 A.L.R.3d 746
     (1974) (“Many courts, with or without expressly
    stating the general rule, have stated that the admission of a
    recording that is partially inaudible or that reproduces only
    part of a statement or conversation is largely a matter within
    the trial court’s discretion.”).      However, that discretion must
    take into account “the evidential purpose which the tape
    served.”   Zicarelli, supra, 
    122 N.J. Super. at 239
    .
    When assessing the evidential purpose of the recording, the
    trial court must consider whether it is probative of one or
    multiple theories of the case.     Only then can the court properly
    determine whether the omission “was so substantial as to render
    the recording as a whole untrustworthy.”      Dye, supra, 
    60 N.J. at 531
     (citations and internal quotation marks omitted); see
    Cusmano, 
    supra,
     
    274 N.J. Super. at 514-15
    .      Where, as here, the
    recording contains competent relevant evidence relating to two
    distinguishable evidentiary purposes, the question becomes
    whether the recording must be precluded in its entirety.
    22
    Although we have not squarely addressed this question before,
    our rules of evidence provide some guidance.
    Where evidence is admissible for one purpose but not for
    another, the trial court “upon request[] shall restrict the
    evidence to its proper scope and shall instruct the jury
    accordingly.”   N.J.R.E. 105.   Thus, to the extent it remains
    competent and relevant, the trial court may admit an otherwise
    admissible recording while redacting a portion deemed
    inadmissible due to an omission or defect.     See Wakefield,
    
    supra,
     
    190 N.J. at 482-83
     (approving trial court’s admission of
    victim impact statement with redaction of “inflammatory
    comments”); State v. Figueroa, 
    358 N.J. Super. 317
    , 325-26 (App.
    Div. 2003) (approving trial court’s admission of confession with
    redaction of references to other crimes).
    The Appellate Division’s reasoning in Zicarelli, which we
    find persuasive, further suggests redaction is appropriate in
    this case.   There, the Appellate Division addressed Zicarelli’s
    contention that the trial court erred in admitting taped
    conversations between Zicarelli and Policastro, the State’s
    witness, because the taped recording was “largely inaudible and
    unintelligible.”   Zicarelli, supra, 
    122 N.J. Super. at 238-39
    .
    Zicarelli and Policastro had known each other for fifteen years,
    during which time Policastor “acted as a courier for Zicarelli
    23
    in carrying ‘pay-offs’ to certain public officials.”      
    Id. at 238
    .
    The Appellate Division held that, although “a substantial
    part” of the recording was inaudible,
    the tape of the conversation between
    Policastro and Zicarelli . . . proved the
    intimacy between them and, considered with
    Policastro’s direct testimony, the
    relationship of that intimacy to the central
    conspiracy of suppressing prosecution of the
    gambling enterprise headed by Zicarelli.
    Therefore, it had probative value to that
    extent, and was admissible for that purpose.
    [Id. at 239.]
    The Appellate Division then distinguished Driver, noting that
    the inaudibility of the tape [in Driver] was
    central to the purpose for which it was
    offered and, because it was largely
    inaudible . . . it would have been grossly
    unfair to admit it. As said above, the
    Policastro-Zicarelli tape had probative
    value for reasons other than what was said.
    Inaudibility had no relevance to those
    reasons.
    [Id. at 239-40.]
    Similarly, the recorded conversation between defendant and
    Aikens was probative in more than one respect: (1) defendant’s
    responses to Aikens’ claim that he owed her money creates an
    inference that defendant was offering Aikens money to alter her
    testimony; (2) defendant’s statements about what Aikens’
    testimony might be suggests he was coaching her to deceive the
    prosecution; and (3) Aikens’ statement that she saw defendant
    24
    with a gun supports the State’s assertion that defendant
    possessed the gun for which he has been charged.   The failure to
    record defendant’s response, if any, to Aikens’ statement that
    she saw defendant with a gun renders that portion of the
    conversation unduly prejudicial with respect to the weapons
    charge.   However, there is nothing in the record to suggest that
    the omission created a risk of undue prejudice with respect to
    the bribery and witness-tampering charges.   Nor does it appear
    that the omission has any impact on defendant’s response that
    “[n]obody seen the gun that day.”
    According appropriate deference to the motion judge’s
    findings, we hold that the recording was admissible up to and
    including the point at which defendant stated: “Nobody seen the
    gun that day.”   Admitting the recording beyond that point
    unfairly asks the jurors to speculate about the content of
    defendant’s reply, see State v. Frost, 
    158 N.J. 76
    , 86 (1998)
    (finding prosecutor’s comments that “unfairly invite[] the jury
    to speculate” improper); see also McKnight v. State, 
    1 N.E.3d 193
    , 202-03 (Ind. Ct. App. 2013) (finding tape recording “must
    be of such clarity and completeness to preempt speculation in
    the minds of jurors as to its content” (quoting Dearman v.
    State, 
    743 N.E.2d 757
    , 762 (Ind. 2001)); whereas excluding the
    recording before that point needlessly deprives the State of
    competent, relevant, and admissible evidence.
    25
    VI.
    In conclusion, we hold that a trial court must employ a
    two-part analysis when considering the admissibility of a
    recording containing partial omissions.   The court must first
    determine if the omission is unduly prejudicial; that is, does
    the omission adversely impact the trustworthiness of the
    recording.   That is an objective analysis that should focus on
    the evidentiary purposes for which the recording is being
    offered.   If the trial court in its discretion finds the
    omission unduly prejudicial, it must then consider whether the
    omission renders all or only some of the recording
    untrustworthy, and suppress only the portion of the recording
    that is rendered untrustworthy.
    While the Driver analysis remains relevant to the above
    determinations, a recording’s shortcomings with respect to one
    factor do not automatically necessitate exclusion of the entire
    recording.   Rather, the court should consider the factors set
    forth in Driver together, on a case-by-case basis, to determine
    whether and to what extent the recording contains competent
    relevant evidence.
    The recording here was offered for two evidentiary
    purposes: to demonstrate defendant’s intent to tamper with the
    State’s witness and to show that defendant possessed the gun for
    which he was charged with unlawful possession.   The
    26
    unintentional omission rendered untrustworthy and unduly
    prejudicial only the portion of the recording in which Aikens
    accused defendant of possessing the gun; it did not adversely
    affect the balance of the recording.
    VII.
    Accordingly, the judgment of the Appellate Division
    admitting the recording in its entirety is reversed, and the
    matter is remanded to the trial court for further proceedings
    consistent with this opinion.
    CHIEF JUSTICE RABNER; JUSTICES LaVECCHIA, ALBIN, PATTERSON,
