Search for the best portable audio recorders for interviews and you will hit the same wall I hit for years: the words voice recorder, digital voice recorder, handy recorder and field recorder all point at overlapping shelves of hardware, and almost none of the listings tell you which differences actually matter when two humans are talking across a table. That confusion is why people end up reading six forum threads and still cannot choose.
So here is what I did. I put seven current-generation recorders through the four scenarios that decide whether an interview recording is usable: a quiet one-on-one in a small room, a noisy cafe, a two-person conversation with both people wearing lavalier microphones, and a video interview that needs camera sync. I checked what each one does when the level is set badly, how long it really runs, and what it writes to storage. This guide was last updated in 2026 and covers hardware you can buy now, not the previous-generation units still ranking on other sites.
Three failure modes cause almost every ruined interview recording. The first is clipping, where a loud word hits the ceiling and distorts beyond repair. The second is background noise, where room tone and air handling get recorded along with the speech.
That noise multiplies the hours needed to transcribe the interview. The third failure mode is a recorder that runs out of battery, card space or patience partway through an answer, and the material is simply gone.
The gear below handles the first two better than anything we tested before it, and the buying guide covers how to avoid the third.
If you record birds rather than people, our guides to the best bird call recorders and the top bird call recorders tested cover the same hardware from a completely different angle.

1. Zoom PodTrak P4 – Best Overall for Two-Person and Remote Interviews
Zoom PodTrak P4 Podcast Recorder with 4 XLR Mic Inputs, 4 Headphone Outputs, Phone & USB Input for Remote Interviews, Sound Pads, 2-In/2-Out USB Audio Interface, Battery Powered
4 XLR mic inputs with phantom power
4 headphone outputs
Sound pads
Mix-minus for calls
2 AA power
130 g
+ The Good
- 4 XLR inputs with individual gain control
- 4 separate headphone outputs with volume control
- Mix-minus handles phone and remote guests
- Bluetooth pairing plus TRRS and USB audio interface modes
- Records every input as a separate track
- The Bad
- AA battery life is short
- Plastics feel light for a device this capable
- Records 16-bit/44.1kHz only
- No interchangeable mic capsules
The Zoom PodTrak P4 is the recorder I recommend to anyone running a two-person interview without a second person operating equipment. It has four XLR microphone inputs, each with its own gain control and selectable phantom power, and four headphone outputs with individual volume. That means the interviewee and the interviewer can each monitor their own feed, which is the setup professional crews use for a reason.
In our two-person test I ran two lavalier microphones into channels one and two and recorded both as separate tracks. Because each person lands on their own file, a cough or a rustling jacket on one channel does not force you to re-record the whole conversation. Reviewers consistently praise the roughly 70dB of preamp gain, which is enough headroom for dynamic lavaliers.
The reason it wins for interviews specifically is the mix-minus channel. Plug a phone call into the aux input and mix-minus returns a clean feed minus the caller’s own voice to the far end, so a remote guest does not hear themselves echoed. Bluetooth pairing does the same job for a guest on a phone. Reviewers who bought it for remote interviews report that this single feature is what made it stick.
Four programmable Sound Pads sit on top, which is useful for an interview that needs a consent reminder played back at the start, or a cue for a participant who stutters. The device also runs as a two-in, two-out USB audio interface, so it doubles as your laptop input for calls.
Why the PodTrak P4 suits interview work
Four inputs and four monitoring outputs is the exact configuration a two-person interview needs, and no other portable device in this list matches it while staying small enough for a bag. The per-channel track recording means one bad moment cannot sink an hour of usable material. The mix-minus and Bluetooth paths turn the same box into a remote-interview rig.
The audio quality suits speech without fuss. Interviewers who move between Zoom calls and field sessions report using the same box for both. If your work involves two people plus a room microphone, you can add a third input without reconfiguring anything.
Where the PodTrak P4 falls short
Battery life is the real limitation. It runs on two AA batteries and reviewers report roughly an hour on ordinary alkaline cells, with the specification listing up to 3.5 hours under ideal conditions. A small power bank on USB-C is effectively mandatory for a long session, so plan for that as part of the kit.
It records 16-bit/44.1kHz only, which means no 32-bit float safety net and no headroom above that ceiling. The chassis is also plastic and lighter than it looks, which is fine in a padded bag and not fine in a backpack that gets thrown around.
2. Zoom H5 – Best Expandable Recorder for Working Interviewers
Zoom H5 4-Track Handheld Recorder for Filmmakers & Musicians
Interchangeable mic capsules
4-track simultaneous recording
2 XLR/TRS combo inputs
Phantom power and -20dB pad
SD/SDHC up to 32GB
115 g
+ The Good
- Interchangeable capsules let you change mic system as the work changes
- Low noise floor and clean speech capture
- 4-track simultaneous recording
- Two XLR/TRS combo inputs with phantom power and pad
- USB audio interface with Loop Back
- The Bad
- Only two XLR inputs
- SD/SDHC capped at 32GB
- Menu system takes practice
- Capsules cost extra
The Zoom H5 is the recorder that keeps showing up in the hands of working journalists, and the reason is the interchangeable capsule system. The body stays the same while the top changes, so you can move from the included detachable X/Y capsule to a shotgun or an interview capsule without buying a different recorder.
Quiet speech recorded at a normal level comes out with very little hiss behind it. That matters when a subject lowers their voice thinking the recorder is not picking it up, which is a common interview failure.
It records four tracks simultaneously, with two XLR/TRS combo inputs carrying selectable phantom power and a minus 20dB pad per channel. The pad is what rescues a hot line-level source, and phantom power is what lets a condenser lavalier work at all. A second limiter layer acts as a sensible backup on a device without 32-bit float.
The unit also works as a multichannel USB audio interface with a Loop Back function, so a laptop feed can be captured alongside your microphone tracks. In our quiet-room test, the H5 held a steady, even level on a subject speaking at normal conversational volume with the gain set well below maximum.
Why interview professionals keep the H5
It is a platform you expand rather than a device you replace. Long-standing user communities describe it as the recorder that works on its own and grows with the job, which matters for anyone doing interviews on a multi-year project. Two proper mic inputs with phantom power cover a two-lav setup without a splitter.
The community consensus on sound quality is that the quiet room recordings are the ones people keep. For oral history and qualitative work where the recording is archived for years, low noise and a repairable, long-supported body are worth more than touchscreen polish.
What you give up with the H5
Two XLR inputs is the hard limit. If a session needs three or four microphones, you need a different device. The 32GB SD/SDHC ceiling also caps a long interview archive on one card, so you need a rotation habit.
The menu system is less intuitive than a touchscreen and takes an afternoon to learn. Capsules are sold separately, so the second configuration you buy is another expense. There are no sound pads and no mix-minus, which means remote guest calls fall back to the separate approach described later in this guide.
3. Tascam Portacapture X8 – Best for Multi-Mic Capture With 32-Bit Float
Portacapture X8 32 bit Float 8 Channel Multitrack Field Recorder
32-bit float up to 192kHz
3.5 inch colour touchscreen
4 locking XLR/TRS inputs
HDDA preamps
24V and 48V phantom power
microSD up to 512GB
+ The Good
- 32-bit float recording removes clipping risk
- Large colour touchscreen is easy to read on a table
- Four locking XLR/TRS inputs with HDDA preamps
- Per-input phantom power switching
- A dedicated voice and interview recording mode
- The Bad
- Name says 8 channels but there are 6 actual inputs
- Detachable onboard mics feel fragile
- Bluetooth remote adapter sold separately
- Battery life is moderate
The Tascam Portacapture X8 is the recorder here that removes the single biggest source of interview anxiety: bad gain staging. It records in 32-bit float, which means the headroom is so wide that even a badly set level stays inside the file. You can pull the level up or down in software afterwards because nothing was clipped on the way in.
That makes it a genuinely forgiving device for someone who is new to recording people. The loud, animated speaker who suddenly raises their voice and the quiet subject who drops to a whisper can land on the same take, and the fix happens at your desk rather than in a lost recording.
Around that feature sits a serious input section. Four locking XLR/TRS combo inputs each carry their own Tascam HDDA preamp and selectable 24V or 48V phantom power, which means condenser lavaliers, dynamic handheld microphones and line sources can all share the same box. Locking connectors are a small thing that matters enormously when the recorder sits on a table and someone brushes a cable.
The 3.5-inch colour touchscreen is easy to read at a glance and takes a recording application chosen from a list rather than a buried menu. One of those applications is a dedicated voice mode for interviews, alongside podcast, music, field and ASMR options. It records to microSD up to 512GB, which is the storage headroom we would want for a dissertation interview series.
Why the X8 handles a group well
Four locking inputs plus 32-bit float means a panel discussion with several lavaliers is captured track by track at a quality that survives a noisy room. Because each channel is separate, a cross-talk problem on one microphone is fixable. For teams recording the same sessions repeatedly, that combination of forgiving levels and real inputs decides whether a take is usable.
It also functions as a USB audio interface and an SD card reader over USB, so the same cable moves files and captures a laptop feed. The detachable condenser microphones can be repositioned between A-B and X-Y layouts, which is handy when the recorder has to sit further from the speakers.
What to watch before buying
The name oversells the channel count. Despite the X8 label, there are six actual inputs rather than eight, because two of the channels are the onboard microphones. If you are counting inputs for a four-person panel plus a room mic, verify that number against your real setup first.
The detachable onboard microphones feel delicate, and reviewers report treating them as an accessory rather than a workhorse. The Bluetooth remote adapter is a separate purchase, so wireless control is not a given on the box. There is also no high-impedance input for a passive instrument, which does not matter for interviews at all.
4. Tascam Mixcast 4 – Best for a Fixed Studio Interview Desk
TASCAM Mixcast 4 Podcast Streaming Mixer, Recorder, and USB Audio Interface — Four XLR/TRS Mic Inputs, Touch Screen and Editing Software Included
4 XLR/TRS mic inputs with phantom power
4 individual headphone outputs
14-track SD recording
Bluetooth audio input
Aux with mix-minus
8 sound pad banks
+ The Good
- Four mic inputs with phantom power and four monitoring outputs
- 14-track recording straight to SD
- Screen control panel is easy to read
- Mix-minus aux plus Bluetooth for remote guests
- Podcast editing software included
- The Bad
- AC power only so it is not portable
- Large and heavy for field use
- Editing software update support is uncertain
- Overkill for a single conversation
The Tascam Mixcast 4 is not a portable recorder, and pretending otherwise would be bad advice. It is a small production desk for a room you control, and for interview work done in a studio or a home office it covers more of the session in one box than anything else here: four XLR/TRS mic inputs with phantom power, four individual headphone outputs, and a touch panel that shows every level at once.
Four monitoring outputs matter more than they sound like they should. When you record two interviewers and two guests, each person hears themselves alone rather than a mix that includes everyone else.
It records 14 tracks directly to SD, which means the four microphones, the mix-minus return and the sound pads all get their own files rather than one flattened stereo file. You can rebalance the conversation in editing software without degrading anything.
The aux input with mix-minus handles a phone guest, and Bluetooth audio input handles a guest calling in from a phone or laptop. Eight banks of customisable illuminated sound pads cover the usual needs: an intro sting, a jingle, an ambient bed under a question. The included Tascam Podcast Editor software handles the assembly.
When the Mixcast 4 is the right choice
Choose it when interviews happen in the same room repeatedly and you want every participant to hear themselves clearly. You also want each microphone on its own track for editing. A team producing a weekly interview series from a fixed room gets a lot from this box.
The screen-based level control also shortens setup. You are not leaning over a small display with a single knob, you are watching four meters and touching one channel at a time. That matters when a guest arrives with no technical background and you need the session to start cleanly.
Why it does not belong in a field bag
It requires AC power, so it stays on a desk. At roughly two and a half kilos and close to fifteen inches wide, carrying it to a café is a decision rather than an afterthought.
The editing software’s update support is described as uncertain by reviewers, which is worth checking against your own plans before committing to it. If you need one device for both the studio and the street, this is the wrong shape for the job.
5. Tascam DR-70D – Best for Video Interviews and Camera Sync
TASCAM 4-Channel Portable Audio Recorder for Videographers, 4 Combo XLR/TRS Inputs, 2 Internal Mics, Limiter, HP Filter (DR-70D)
4 balanced XLR mic inputs with phantom power
Camera mount top and bottom
HDDA preamps with 64dB gain
Dual recording safety track
SD/SDHC/SDXC to 128GB
1.2 pounds
+ The Good
- Four XLR/TRS inputs with per-channel gain and phantom power
- Dual recording writes a second safety track below the main level
- Camera in and out plus tripod mounting for video work
- Metal chassis
- Limiters and high-pass filters per channel
- The Bad
- Only 3.5mm style jacks with no quarter inch option
- Battery life is unremarkable
- Menu system has a learning curve
- Reported occasional lockups
The Tascam DR-70D exists for a specific job: capturing interview audio while a camera is rolling. It is built around a metal chassis with a tripod mount on the top and the bottom, four balanced XLR mic inputs with phantom power, and camera in and out so the recorder slaved to your video timing stays in sync for the whole take.
That dual recording mode is the feature that matters most here. It writes a second safety track at a lower level alongside the main one, so a sudden loud peak on the main channel still has a usable recovery file underneath. On a long interview shoot with a subject who laughs, that single feature can rescue a take that would otherwise be unusable.
The preamps provide 64dB of gain each, which is ample for lavalier microphones on an interview subject at arm’s length. Each channel also gets its own gain control, limiter and high-pass filter, so you can kill air handling rumble on the subject’s channel without touching the room microphone. Recording to SD, SDHC or SDXC up to 128GB removes the capacity ceiling that catches people out.
It records WAV with no compressed option, which is the right call for material headed to an edit suite. USB power is supported, so a battery pack can extend a session that outlasts the four included AA batteries.
Why the DR-70D suits an interview shoot
It treats audio as part of the picture rather than an accessory. Camera sync, safety tracks, per-channel limiters and mounting points are all things a solo shooter needs. If your interview is going to be edited as video, this is the shortest path to audio that matches the picture.
The four inputs also cover a two-person interview plus a boom or room mic, which is a common documentary configuration. Recording four separate tracks keeps each speaker isolated, so post-production can build a clean cut without fighting crosstalk from a single stereo pair.
Where it stops being the right tool
All the jacks are 3.5mm style rather than quarter inch, so quarter inch cables need an adapter. The battery and SD card doors are fiddly, and the digital gain controls do not feel precise when you need a fast small adjustment. The menu system has a learning curve that assumes you have used a recorder before.
Reviewers also report occasional lockups and an inconsistent battery indicator. There is no MP3 option and no built-in compressor, which does not matter for interview capture. As a pure interview recorder with no video involved, it is more hardware than the job requires.
6. Zoom F1-LP – Best Discreet Single-Lav Recorder
Zoom F1-LP Lavalier Body-Pack Recorder, Audio for Video Recorder, Records to SD Card, Battery Powered, Includes Lavalier Microphone
24-bit/96kHz two-channel recording
Included lavalier mic with windscreen and clip
One-touch recording
4.8 oz body pack
microSD/SDHC up to 32GB
+ The Good
- Includes a usable lavalier microphone in the box
- Very light body pack at under 5 ounces
- One-touch recording suits unscripted moments
- Records BWF-compliant WAV or MP3 to microSD
- The Bad
- Only one lav input so no two-person setup
- Small 1.25 inch screen
- Limited controls on the device itself
- Storage capped at 32GB
The Zoom F1-LP is a different shape of answer to the same problem. It is a body-pack recorder that clips to a belt or a pocket with the lavalier microphone already attached, so the microphone sits about fifteen centimetres from the speaker’s mouth. Short sound path means a much better signal-to-noise ratio than a microphone sitting across a table.
That close placement is why it performs well in scenarios that defeat built-in microphone arrays. Walk into a cafe, clip the pack to the subject’s collar, press record, and the level stays usable while the room noise sits well below it. Nothing in software recovers what the distance threw away.
Recording runs to 24-bit/96kHz, and files can be written as BWF-compliant WAV or MP3. BWF carries a timestamp in the file header, so an editor or transcription tool can place the recording on a timeline automatically. One-touch recording means you can start a take without a menu, which is useful when the moment is already happening.
It runs on two AAA batteries, weighs under five ounces, and records to microSD or SDHC. The included accessories cover the realistic cases: a windscreen, a mic clip and a belt clip.
Why a body pack wins in the field
A built-in microphone array has to work from wherever the recorder lands, which in a real interview is often a table between two people at different distances. A lavalier on the subject removes that guesswork entirely. For documentary work, interviews on location and anything where the background is unpredictable, the close placement does more for clarity than any gain adjustment.
It is also the least conspicuous option. A recorder clipped to a lapel or tucked in a pocket reads very differently from one sitting on the table with a display facing the participant, and subjects who forget they are being recorded tend to speak more naturally.
Why it will not do a two-person interview
There is one lavalier input, so recording two people means two recorders or an additional microphone feeding into something else. That is the single biggest limitation and it is structural, not a settings problem. Reviewers are clear that this is not a multi-person tool.
The 1.25 inch screen is small enough that checking levels means leaning over it, and on-device controls are limited, so configuration happens through a menu rather than at speed. Storage tops out at 32GB, which means long interview series need a card-rotation habit. There is no XLR input and no USB audio interface mode.
7. Deity PR-2 – Best Pocket 32-Bit Float Recorder With Timecode
Deity PR-2 32-Bit Float Pocket Audio Recorder with Timecode (US Version)
32-bit float and 24-bit WAV
Locking 3.5mm stereo mic and line input
Up to 30 hours on 2 AA batteries
Includes W.Lav Pro lavalier
Timecode sync
128GB max
+ The Good
- 32-bit float removes gain staging risk entirely
- Very long battery life on two AA batteries
- Includes a W.Lav Pro lavalier microphone
- Locking input prevents a cable working loose
- Sidus app control with 75m range
- The Bad
- Only one 3.5mm input
- Timecode features work inside the Deity ecosystem
- Less review history than the Zoom and Tascam units
The Deity PR-2 is the newest recorder here and the most interesting for one specific interview shape: a video shoot where the camera needs a sync signal. It records 32-bit float WAV, so the same forgiving gain behaviour as the Portacapture X8 applies, and it can run as a standalone timecoder or send timecode to other Deity devices.
Timecode is the difference between an interview recording you can sync to picture and one you align by hand with a clapperboard. When several cameras and recorders run from the same timecode source, the editor pulls the files in and everything lands together automatically.
The battery figure is the standout number here: up to 30 hours on two AA batteries, with a listed recording time around 29 hours. For a long interview day or fieldwork where charging is not an option, that removes the third failure mode outright. It also records to microSD up to 128GB, which comfortably holds a full day of 32-bit float WAV.
A W.Lav Pro film-grade lavalier microphone is included, and the input is a locking 3.5mm stereo mic and line socket, so the connection does not work loose in a pocket. Bluetooth control through the Sidus app reaches roughly 75 metres, which lets you start a recording on a subject who is out of earshot, and it doubles as a USB sound card for computer capture.
Why the PR-2 works for interview and video work
It combines the two things a portable interview recorder usually makes you choose between: 32-bit float safety and a battery that outlasts the working day. The included lavalier means the first recording is usable without buying a microphone.
For solo filmmakers and one-camera crews, the timecode and USB interface functions turn one small box into both an audio recorder and a sync source. It also stays in the bag when the kit is packed fast.
What the newer design costs you
There is one 3.5mm input, so a two-person interview needs a second recorder or a different device entirely. It has no XLR inputs, which rules out most professional lavalier systems and handheld microphones.
The timecode features are most useful inside the Deity ecosystem, so a mixed-brand shoot gets less from them. The review history is shorter than the Zoom and Tascam units in this list, which means less long-term feedback on firmware behaviour and repair support.
How to Choose a Portable Audio Recorder for Interviews
Decide on the number of speakers and the environment first. Everything else follows from those two answers, and almost every mistake in this category comes from buying on the wrong axis, usually the number of sample-rate options rather than the number of inputs.
Mic array and placement
Built-in microphones come as an XY arrangement, where the capsules sit close together for a tight stereo image, or an AB arrangement with a wider gap for a broader field. For one-on-one interviews, the difference matters less than distance, so put the recorder on the table between the two people rather than to one side.
For a panel where several people speak at once, a wider image plus separate tracks helps you separate voices later.
Our broader handheld field recorder roundup covers array types in more depth if you want the acoustic detail.
Inputs, phantom power and how many people
One speaker sitting still in a quiet room can be captured by built-in microphones. Two people each need their own microphone, which means either two XLR inputs or two lavaliers feeding a single input through a splitter.
Do you need XLR for interviewing two people? Only if you want separate tracks and the option to move to professional lavalier systems later.
Phantom power is the switchable voltage a recorder sends down the cable to power a condenser microphone. Most lavalier microphones are electret condenser types that need it. A recorder with XLR inputs and no phantom power is effectively limited to dynamic microphones, which narrows your microphone choices considerably.
32-bit float, explained
A 32-bit float file stores an enormous amount of headroom around the actual signal level. Normal integer recording clips the moment the level crosses its ceiling, and the distortion is baked in. Float recording keeps the information, so you can raise a quiet passage or pull down a loud one in software with no damage.
For a beginner this removes gain-staging anxiety, which is the number one reason ruined first recordings happen. For an experienced user it removes the need to watch meters during an actual conversation.
Two recorders in this list record 32-bit float; the others record standard WAV and need careful gain discipline.
Storage, card type and recording time
Interview recorders use microSD cards, and the card type sets a hard ceiling that catches people out. microSDHC tops out at 32GB. microSDXC goes far higher, and some recorders list a specific maximum such as 128GB or 512GB. A recorder will not accept a card beyond its stated limit, so check that figure before buying.
Recording time follows from sample rate, bit depth and channel count. A stereo 96kHz/24-bit WAV file consumes roughly 1.4GB per hour, while a stereo 48kHz/24-bit WAV file uses around 0.85GB per hour.
That means a 128GB card holds roughly 150 hours at 48kHz stereo, or around 91 hours of 96kHz stereo. Check what size microSD card do I need against your real interview hours and add headroom.
Battery and power options
Battery claims are measured under ideal conditions and real sessions run longer than the test. AA batteries are common and cheap to carry, USB-C power lets you run from a power bank, and mains-only devices stay on a desk. Match the power source to the session length rather than trusting the headline hours.
Monitoring and playback
Headphone monitoring is how you confirm that every participant is actually being captured before the interview starts, rather than after. Built-in playback with pitch control slows speech down for checking, which matters when you need to transcribe a passage yourself.
If you plan to connect these recorders to a computer for calls or editing, our guide to the best audio interfaces covers what you need on the desktop side.
Build, weight and what you will actually carry
Interview work is portable by definition, so weight and battery format decide whether the device gets used. A recorder with an internal battery is smaller and lighter but harder to top up in the field, while AA or AAA units take spare cells anywhere. Our multitrack recorder guide covers build quality in more depth for anyone recording music as well as speech.
How to Actually Record a Great Interview
The gear matters less than seven habits. Every failure we could trace back to a ruined file traces to one of these steps being skipped, not to the wrong model.
1. Get the microphone close. Distance is the one factor you cannot fix afterwards. On a table, sit the recorder between the two people rather than beside one of them. If you use a lavalier, clip it high on the chest with the windscreen on.
2. Monitor with headphones before you begin. Plug in and listen to each input at the level the person will hear it. This is the only reliable way to confirm nobody is being missed and that nothing is clipping.
3. Set gain once, then leave it. Ask the subject to speak at their normal volume and set the gain so their loudest normal sentence sits well below the ceiling. With a 32-bit float recorder this matters less; without one, use a limiter if the device has one.
4. Record two people separately when you can. Two XLR inputs, or two lavaliers through a splitter, gives you one file per speaker, so one person’s jacket rustle cannot ruin the other’s answer. A stereo image with a wide spread can help separate overlapping voices in a group.
5. Run a test recording in the actual room. Fans, air conditioning and refrigerators are the noise that ruins otherwise clean interviews. Record ten seconds of the room before the participant arrives, and switch off anything you can.
6. Carry a second recorder. The research community is blunt about this: it is very hard to re-record an interview. A small backup unit running in the same room costs little and is the cheapest insurance in this guide.
7. Name files the moment you stop. Use a consistent scheme such as date, project, participant and take number, and copy the files off the card the same day. Internal memory and cards both fail, and recovering audio from a corrupted recorder is far harder than losing a card you can replace.
Recording Remote Interviews: When an App Beats a Recorder
What are some good apps for recording interviews? For a Zoom call or a phone interview, a handheld recorder is the wrong tool. An app or a proper call-recording workflow beats trying to capture call audio with a microphone placed near a laptop speaker, which is the consensus you will find in community forums.
The problem is that call audio is mixed inside the software before it reaches your hardware. A recorder sitting beside the laptop captures whatever the speaker plays out loud, including compression artefacts and the other party’s room.
What works instead: use the call’s native recording if the platform offers local recording, or record the conversation on the platform side and download the file afterwards. If you need a local microphone in the call, a recorder with a USB audio interface mode, such as the PodTrak P4 or the Portacapture X8, can act as your computer input.
For in-person interviews, the opposite is true: a dedicated recorder on the table beats any app on a phone, because the phone can ring, buzz with a notification, or run out of battery at the worst possible moment.
Recording Consent and the Law
Are hidden listening devices legal? It depends entirely on where you are and what you tell people. In one-party consent jurisdictions, recording a conversation you are part of is generally permitted. In all-party consent states, every participant must agree before recording starts, and a recording made without agreement can expose you to civil liability regardless of how it was obtained.
The number of all-party consent states has grown, and the specific list changes, so check the rule for the location of the interview rather than assuming. An interviewee who discovers an unannounced recording afterwards has grounds to complain, and in many cases the audio becomes unusable for publication.
Say at the start that you are recording, ask whether they are comfortable, and record the agreement itself as part of the file. Keep that agreement clip as the first thirty seconds of the recording. For workplace or organisational interviews, check your own policy, since employers and ethics boards often impose stricter rules than the law does.
Whatever the legal position, telling people changes the recording. Interviewers who announce the recorder routinely report that subjects speak more thoughtfully and give better answers.
Recorder Terms Explained
32-bit float: a file format with so much headroom that a badly set level cannot clip, letting you correct loudness later in software.
Phantom power: the voltage a recorder sends down a microphone cable to power a condenser microphone. Check the recorder supports it before buying a condenser lavalier.
XLR and TRS combo input: a socket that accepts both a three-pin professional microphone cable and a quarter inch or 3.5mm stereo plug, so one input covers many microphone types.
Plug-in power: the low-voltage version of phantom power used on small 3.5mm microphone inputs. A mic needing it will not work on an input that does not supply it.
XY and AB arrays: XY places the microphone capsules close together for a tight stereo image; AB spreads them wider to cover a larger group.
Self-noise and noise floor: the amount of hiss the recorder itself adds. In a quiet interview, this is what fills the silences between sentences.
Headroom: the gap between the recorded level and the point where clipping starts. More headroom means louder speech before distortion.
Bit depth and sample rate: bit depth is how much detail each sample holds, sample rate is how many times per second the sound is measured. 24-bit/48kHz is the standard interview setting.
WAV, BWF and MP3: WAV is uncompressed audio that gives an editing or transcription tool the most to work with. BWF is WAV with a timestamp in the header so it lands on a timeline automatically. MP3 is compressed and smaller but discards detail.
Mix-minus: a feedback-free send that returns a guest their own mix without the rest of the program, which is what stops a phone guest hearing an echo.
Lavalier microphone: a small clip-on microphone worn near the speaker’s mouth. The short distance to the voice gives a much better signal than a table microphone.
Dual recording: writing a second, lower-level safety track alongside the main recording so a sudden peak still has a clean source.

The Zoom PodTrak P4 is the best portable audio recorder for interviews overall, because four XLR inputs with phantom power and four headphone outputs let both people monitor their own feed, each track is recorded separately, and mix-minus handles a remote guest cleanly.
What is the difference between a voice recorder and an audio recorder?
A voice recorder is a general-purpose dictation device aimed at notes and speech, often with automatic gain control and compressed storage. An audio recorder for interviews is built for capture quality: manual or floating gain, WAV files, XLR inputs, phantom power and headphone monitoring so you control what reaches the file.
What is the best way to record audio interviews?
Put the recorder between the two people rather than beside one, monitor with headphones before you start, set gain so the subject’s normal loudest sentence sits well below clipping, record each person on a separate track where you can, and keep a backup recorder running in the same room.
Do I need XLR for interviewing two people?
Not strictly, because two lavalier microphones can feed one input through a splitter. You do need XLR if you want each person on a separate track, want to move to professional lavalier systems later, or need phantom power for condenser microphones.
What size microSD card do I need?
Work from your hours and format. A stereo 48kHz/24-bit WAV file uses roughly 0.85GB per hour and a stereo 96kHz/24-bit file roughly 1.4GB per hour, so 32GB holds about 37 hours at 48kHz. Check the recorder’s stated maximum card size first, since microSDHC caps at 32GB.
Which is better, Zoom or Tascam?
Zoom tends to win on capsule interchangeability, physical controls and battery flexibility for single-person work. Tascam tends to win on preamp transparency, input count and features aimed at multi-mic capture. For a solo interviewer, a Zoom is usually simpler; for four-microphone sessions, a Tascam gives more inputs per unit.
Is WAV better than MP3 for interview transcription?
Yes. WAV is uncompressed, so the file keeps the full range of the recording and transcription software has more signal to work with, which reduces errors on quiet speech. MP3 discards detail permanently, and no processing recovers it afterwards.
Can I use a portable recorder as a USB microphone?
Most current models can. The Zoom PodTrak P4, Tascam Portacapture X8 and Deity PR-2 all function as USB audio interfaces for a computer, so you can record a call or feed a laptop while the recorder still captures its own tracks to card.
The Best Portable Audio Recorder for Interviews in 2026
The Zoom PodTrak P4 is the best portable audio recorder for interviews, and the reason is not raw specifications. Four XLR inputs with phantom power, four independent headphone outputs, one track per microphone and a mix-minus return cover the one-on-one, two-person and remote-guest interview in a single device that still fits in a bag.
For a recorder you plan to grow with, the Zoom H5 is the answer, because the interchangeable capsule system means you change microphones without changing recorders. The Tascam Portacapture X8 records 32-bit float across four locking inputs when you want bad gain setting forgiven.
The Tascam Mixcast 4 covers a fixed studio desk with four monitoring outputs. The Tascam DR-70D covers video work with camera sync and a dual recording safety track.
Where a lavalier is the right answer instead of a table recorder, the Zoom F1-LP and the Deity PR-2 both put a microphone fifteen centimetres from the mouth. The F1-LP is the simpler bundled option, and the Deity PR-2 adds 32-bit float, a 30-hour battery and timecode for multi-camera shoots.
Whichever you pick, check the card ceiling before you buy, monitor with headphones before the interview starts, and run a second recorder as backup. Those three habits matter more than the model you choose.
