A reliable interview recording starts before you press the button: decide what you need to capture, explain how it will be used, and obtain informed consent. Then test the setup, record the conversation without making it feel like a performance, and check that the file is safe before you rely on it.
You do not need a studio. A phone can be enough for a simple audio conversation; video and remote interviews add checks for framing, software and connection. The steps below work across research, oral history, journalism, work and other settings, but the rules that apply to consent and retention depend on where you are and what the interview is for.
Choose the recording format
Begin with the end use, not the equipment. If you need to quote someone accurately or prepare a transcript, clear audio may be all you need. If gestures, demonstrations or the setting matter, record video. For a remote conversation, decide whether you need the whole call, separate camera feeds, or simply a clean audio record; the available choices depend on the platform and your project.
Make a short plan that answers four questions: what will be recorded, why you need it, who may listen or view it, and how long you expect to keep it. Include whether you might transcribe it, publish excerpts, share it with a team, or use it in a public presentation. The participant should hear these intentions before you ask for consent, not discover them after recording.
| Format | Useful when | Main checks | Trade-off |
|---|---|---|---|
| Phone audio | You need speech for notes, quotes or transcription | Battery, storage, microphone position and a playback test | Simple to carry, but easy to leave too far from the speaker or disturb while handling |
| Recorder and microphone | You want a dedicated audio setup or clearer control over monitoring | Connections, power, recording settings and headphones | More equipment to prepare and learn |
| Video in person | Appearance, gestures, a demonstration or the surroundings matter | Camera framing, light, sound and storage | Captures context but also more identifying information |
| Remote call recording | Participants are in different places | Consent, call controls, microphone, connection and playback | Convenient, but each participant’s local sound and connection can differ |
A smartphone is a reasonable starting point for a basic audio interview if the room is quiet and you test it first. A dedicated recorder, external microphone and headphones can make monitoring easier, but they are options rather than prerequisites. If your work includes a regular video or audio stream, the practical checks in this live-streaming reliability checklist are relevant to thinking about testing and monitoring, though an interview has its own consent and privacy needs.
Get informed consent before recording
Explain the recording in ordinary language before it begins. Tell the participant what you are capturing, the purpose, who will have access, how it may be used, and what will happen to it afterwards. If there are confidentiality limits, planned sharing, or a way to ask for withdrawal, describe those accurately. Do not suggest that a recording is confidential if other people will be able to hear it.
Ask clearly and allow time for a genuine answer. For example: “With your permission, I would like to record this conversation for [purpose]. [People or group] will be able to access it, and we plan to keep it until [retention plan]. Is that acceptable to you?” Adapt the wording to what is true for your project. Digital.gov offers sample wording for its user-research context in its guide to conducting an interview; it is an example, not universal legal language.
Obtain consent before recording, including before taking notes where the applicable guidance or agreement requires that sequence. GOV.UK’s user-research guidance on notes and recordings says to get informed consent from all participants in that setting before notes or recording. That guidance applies to its context, not every interview everywhere. Laws, institutional policies and participant agreements vary by jurisdiction and purpose, so check the current rules that apply to your work rather than treating any one example as universal.
Keep a record of consent in a form suitable for the project: it may be a signed form, an approved digital process, or a recorded verbal confirmation where appropriate. If you record a verbal confirmation, do so only after the participant has agreed to begin recording. Avoid collecting unnecessary identifying details, especially for sensitive research. If someone declines, do not record them; proceed with a non-recorded conversation only if that is acceptable for the project and clearly understood by everyone.
Remote calls need the same care. Tell participants before you activate a recording function, and do not assume that a platform’s notification or a calendar invitation substitutes for an explanation and agreement. If another person joins, pause and explain the recording to them too. When consent is uncertain, stop and clarify rather than hoping it can be resolved later.
Prepare the space and equipment
Choose a place where the participant can speak comfortably and privately enough for the subject. Reduce avoidable noise: close a nearby door or window if practical, silence notification sounds, and move away from fans or machinery that compete with speech. You cannot remove every background sound, but a calmer space makes it easier to understand answers and transcribe them later.
Prepare a flexible outline rather than a script that dictates every sentence. Write topic areas and open-ended questions such as “Can you describe what happened next?” or “What did that change for you?” Leave room for follow-ups. Digital.gov recommends planned but unscripted prompts in its interview guidance, while the National Park Service’s advice on oral-history interviewing emphasises listening and giving the narrator room to tell the story. The aim is a useful conversation, not a recital.
Check the basics before your participant arrives or joins: charge the phone or recorder, confirm available storage, bring any cables or headphones you need, and make sure the recording app or software is ready. If you use an external microphone, check that the device recognises it and that the cable is secure. Keep the recorder close enough to capture speech but positioned so you can monitor it without making the participant feel watched.
For a video interview, consider what appears in frame as well as the sound. Remove papers, screens or objects that should not be recorded. Use a stable surface or support, check that faces are visible, and avoid putting a bright window directly behind the participant. For remote interviews, test the camera, microphone and call connection from the place you will use. A simple setup that you have checked is more dependable than a complicated one you have not rehearsed.
Set up audio and video
Place an audio device on a stable surface and avoid picking it up while someone is speaking. Handling creates noise that can mask words. If an external microphone is available, position it consistently and check what its indicator or meter shows. The American Library Association’s oral-history guide suggests about a hand span, or about five inches, between an external microphone and the speaker’s mouth as a practical starting point. That is source-specific advice, not a specification for every microphone; follow the equipment’s instructions and verify the result by listening.
If you record video, look at the frame before the interview begins. Leave enough space around the participant that their face and natural movement remain visible, and keep the camera steady. For a remote conversation, make sure the participant knows if their image will be recorded and whether the recording captures the entire call or only one feed. Check what other windows or notifications might appear if screen sharing is part of the interview.
Headphones are useful when you need to hear what the microphone is actually capturing. They help reveal echo, a loose cable, a muted input or a distant voice that may not be obvious in the room. They are optional for a phone-only conversation, but become more valuable when you use a separate microphone, monitor a remote call or need to catch problems early.
Choose settings you understand and can reproduce. If the recording software offers several formats or quality options, consult its documentation and ensure the resulting file can be opened on the computer or device where you will review it. There is no single setting that suits every recorder, platform or later use. The important thing is not to chase a label; it is to make a short sample, play it back, and confirm speech is intelligible.
Record a test and check levels
Before the interview, make a brief test in the actual room or call. Ask someone to speak at an ordinary volume, then play the sample through headphones if available. Listen for clear words, hum, echo, clipping, rustling, distant voices and intermittent connection drop-outs. A meter moving on screen does not prove the sound is usable; playback does.
If the sample is hard to understand, fix one cause at a time. Move the microphone closer without putting it in the participant’s way, turn off an avoidable noise source, or choose a quieter position. If you hear distortion, check the input level or microphone placement. If you hear echo on a remote call, check whether speakers and microphones are feeding sound back into one another and whether headphones help. Make another test after changes rather than assuming the fix worked.
For video, play back the sample and check both picture and sound. Confirm that faces are visible, the frame is steady, and the recording includes the intended participants. In a remote call, test the software’s recording control, permissions and playback path before the substantive conversation. A test that cannot be found or opened is not a useful test.
Plan a low-key way to check the setup during the interview. You might glance at the device’s recording indicator or pause at a natural break to confirm that it is still running. Avoid repeatedly interrupting the participant. If you discover a problem, tell them, explain what happened, and ask whether they are happy to continue with a fresh recording; never conceal a failure and imply the full conversation was captured.
Record and keep a backup
At the start, say only what the project needs. A brief slate might include a project identifier, the date, and the participant’s chosen name or reference code. Avoid announcing sensitive personal details simply because it is customary in another setting. If you are recording verbal consent at the opening, first ask and receive permission to start the recorder, then capture the confirmation in the agreed way.
During the conversation, listen more than you speak. Ask one question at a time, give the participant time to think, and follow up when a word, date or sequence is unclear. Prompts such as “What happened after that?” or “Could you give me an example?” invite detail without dictating an answer. The National Park Service’s oral-history guidance is useful here: patient listening supports a conversation in which a narrator can develop their account in their own words.
Check periodically that the device is still recording and that the sound remains acceptable. A glance at the display at a natural pause is often enough. If the participant moves, the cable shifts, a call drops, or a loud interruption occurs, note the point so you can inspect it later. If you need to restart, explain why and confirm that the participant agrees to continue under the same terms.
When the interview ends, thank the participant and remind them of any agreed next steps. Before packing up, confirm that the recording has stopped and that the file is present and playable. Where the device permits it, make a second copy to a secure location before deleting or reusing the original. A backup is not useful if it is stored on an unsecured personal account or shares the same risk as the original, so choose a location with access controls appropriate to the material.
For remote recordings, verify which file is complete and whether it includes all participants before ending the session or closing the application. If the software saves locally and also offers a cloud copy, understand who can access that copy and whether its storage terms fit your project. Do not assume that a recording service’s default retention or sharing settings match what you promised participants.
Review, store, and share the recording
After the session, play enough of the file to confirm it is complete and intelligible. Check the beginning, end and any point where you noticed a problem; for a critical interview, review the whole recording before relying on it. Make a working copy for transcription or editing while retaining the original according to your project’s process. Give files clear, neutral names that do not expose unnecessary personal information.
Store the recording and its consent record securely, with access limited to people who need it. Use only the recording and notes in the ways you explained and agreed. If the material contains personal or confidential details, consider whether those details need to be removed, masked or restricted before sharing an excerpt. Review transcripts and clips too: editing can leave a name, address or other identifying detail visible even when the audio file itself is protected.
Agree and follow a retention plan. Keep files for the period required by the project or applicable policy, then delete them in the manner your process requires. Where appropriate, remove copies from personal devices only after confirming that the secure transfer succeeded. Do not treat deletion from one device as proof that every synced or shared copy has disappeared; check the locations you used.
Before sending a recording to a participant, colleague or editor, check that the recipient and method are appropriate and that the sharing falls within the consent you obtained. If the participant agreed to internal review, that does not automatically mean they agreed to public posting. Revisit the agreement if the intended use changes. If your interview workflow later feeds material into a public video channel, separate that publishing decision from the recording decision; this guide to using recorded classes in a YouTube live playlist illustrates a different distribution context, not permission to publish interview material.
A recording can also become source material for a broadcast or archive. Keep that step distinct: recording someone for review does not automatically mean you may put their words or image into a continuous public stream. If you are planning that kind of channel, this overview of streaming pre-recorded videos without keeping a PC on concerns the mechanics of an always-on stream, while consent and rights still need to be resolved for each recording.

FAQ
How do I record an interview on my phone?
After explaining the purpose and obtaining consent, place the phone on a stable surface in a quiet space, check its battery and storage, and make a test recording. Play the sample back before beginning the full conversation. Keep the phone still and check occasionally that it is still recording.
What do I need to record an interview?
For a basic audio conversation, a smartphone may be enough. A dedicated recorder, external microphone and headphones can help with monitoring or a more controlled setup, while video and remote interviews also require checks of the camera, software and connection. Choose tools for the intended use and test what you have rather than buying equipment by default.
Do I need consent to record an interview?
Obtain informed consent before recording and explain the purpose, access and intended use. The legal and institutional requirements vary by jurisdiction and context, so check the current rules and agreements that apply to your project. Do not treat a participant’s presence on a call or a platform notification as a substitute for an informed agreement.
How can I tell whether an interview recording is usable?
Play back a test and listen for intelligible speech, unwanted noise, distortion and interruptions. For video, check the picture as well as the sound; for remote calls, confirm the file includes the intended speakers. Afterward, review the complete recording before relying on it and make a secure backup.
