Interview and fieldwork recording · How-to guide
The moment an interviewer checks their phone screen, adjusts a recorder, or watches a level meter, the participant notices. That interruption costs rapport — and rapport is what produces honest, detailed responses. A recorder that clips on and disappears lets the interviewer be present for the entire conversation.
Best for fieldwork
Quick answer
Minimize equipment management so the interviewer can stay fully present with the participant.
Choose a room with soft surfaces and minimal background noise. Tell the participant you are recording for accuracy before you press record — a simple verbal confirmation is sufficient in most contexts.
Placement determines audio quality more than which device you use. Close-range audio from a consistent position gives any transcription tool enough signal to work with.
Play back 10–15 seconds with headphones on and check that both voices are audible and levels are not clipping. Fix placement issues now, not after an hour of recording.
Battery failure and storage issues lose more fieldwork recordings than bad audio. Copy files to a second drive or cloud backup before the next interview, and rename each file with date, participant, and location while the context is still fresh.
Methods
Compared on audio quality at typical fieldwork distances, how much equipment management is required during the interview itself, battery coverage across a full day of sessions, and whether transcription is built in.
Default for most fieldworkers — requires holding or placing the phone; managing notifications and battery mid-session interrupts the conversation.
Strong audio when well-positioned; but size, cables, and level-monitoring mean constant awareness of the device throughout the interview.
Lav mic improves audio significantly; cable and phone still require positioning and management; battery risk on a full fieldwork day.
Worn on the body; mic stays close to the speaker regardless of movement; 20-hour battery outlasts any fieldwork day; AI transcription with speaker labels after the session.

Tips
A fieldwork recording setup needs to do four things well: stay out of the interviewer's way, outlast a full day of sessions, produce a transcript accurate enough for thematic analysis, and keep files organized across multiple interviews.
The easier way
Plaud NotePin S is a wearable AI note-taking device built for professionals who conduct research interviews and fieldwork. At 17.4 g, it clips to a lapel or lanyard and runs for up to 20 hours — enough for a full day of back-to-back interviews without recharging or managing the device.

NotePin S for wearable in-person fieldwork and 1:1 interviews; Note Pro for research setups that include phone interviews, remote sessions, or conference room panels.

Wearable AI recorder for 1:1 and 1:2 fieldwork interviews.

Best for research that includes phone interviews, remote sessions, or multi-speaker conference panels.
Select a quiet location, position the mic within 15–20 cm of the speaker, and monitor with headphones before starting. These three steps — environment, placement, and a pre-interview test — have more impact on the final recording quality than any equipment upgrade.
For 1:1 and small-group fieldwork, a dedicated recorder worn or positioned close to the speaker produces cleaner audio than a phone placed on a table. The device matters less than the distance from the mic to the speaker's mouth.
Yes. Placement is consistently identified as the primary factor in fieldwork audio quality. A recorder held or worn 15–20 cm from the speaker produces more usable audio than an expensive device left on a table across the room.
Run a backup recording alongside the primary device — battery failure and storage issues cause more lost interviews than poor audio quality. After each session, rename the file with date, participant, and location, and copy it to a second drive or cloud backup.
