You sit at a kitchen table with a small digital recorder, a pair of lapel microphones, and two grandparents ready to share stories. The recorder sits on the table, the mics clip to their shirts, and the room is quiet enough that the only sound is their voices. In this setting, the quality of the audio depends on the tools you bring, the room you choose, and how you prepare before the conversation begins. The steps below keep the setup simple, avoid unnecessary gadgets, and ensure the recording remains clear and usable for years to come.
Essential interview equipment
A basic setup consists of a portable recorder with a built‑in preamp, two cardioid lavalier microphones, and a set of windshields. The recorder should support 24‑bit/48 kHz PCM recording, which offers sufficient fidelity for voice without creating massive files. A small set of spare batteries and a cable for connecting the mics are also useful. Optional items such as a mixer, shotgun microphone, or external audio interface can wait until you encounter specific problems like multiple speakers in a large space. By limiting the gear to these core pieces, you avoid over‑investment while still capturing clear, balanced audio.
Choosing a room and controlling acoustics
Select a room with soft furnishings—cushioned chairs, curtains, or carpet—to absorb reflections and reduce echo. Turn off appliances that generate hum, such as refrigerators or air‑conditioners, and close windows to keep traffic noise out. The single factor that ruins most amateur recordings is a hard, empty space that creates a long reverberation tail; adding a blanket or a portable acoustic panel behind the speakers can mitigate this. Test the room by speaking at normal volume and listening for any ringing or distant sounds; if they are audible, adjust the environment before setting up the microphones.
Mic placement and speaker positioning
Clip each lavalier microphone about 6–8 cm from the speaker’s chest, just below the collar, and point the capsule toward the mouth. Keep the cable away from clothing to avoid rubbing noise. Position the speakers so they face each other slightly angled, rather than directly opposite, which helps each mic capture its intended voice while minimizing cross‑talk. Maintain a distance of roughly 1 m between the two speakers; this distance balances natural conversation flow with a clear separation of audio tracks when the recorder provides dual channels. If the recorder records a single stereo track, place the speakers symmetrically around the device to preserve a balanced left‑right image.
Pre‑interview level check
Before the interview starts, perform a quick level test. Ask each speaker to speak a sentence at their normal volume while you watch the recorder’s meter. Adjust the input gain so the peaks stay within the -12 dB to -6 dB range, leaving headroom for occasional louder moments. Write down the gain settings or take a photo of the display for reference. Once the levels are set, lock the gain if the recorder allows it, and avoid changing settings during the conversation. This prevents sudden volume shifts that would require post‑recording gain correction.
File formats and naming conventions
Record in an uncompressed PCM format such as WAV or AIFF; these files preserve the full quality of the original audio and are widely supported by editing software. Avoid lossy formats like MP3 for archival purposes because they discard data that may be needed later. After stopping the recorder, rename the file immediately using a consistent pattern: YYYY‑MM‑DD_Subject1_Subject2.wav. Including the date and participants makes it easy to locate the file later without opening it. Keep the naming convention simple and avoid spaces or special characters that could cause issues on different operating systems.
Backup strategy for family recordings
Apply the 3‑2‑1 backup rule: keep three copies of each recording, store them on two different media types, and keep one copy off‑site. For example, keep the original WAV file on the recorder’s SD card, copy it to an external hard drive, and upload a duplicate to a cloud storage service. Do not rely on a single copy; hardware failures and accidental deletions are common. Verify each backup by opening the file after transfer. Periodically check that the off‑site copy remains accessible and that the storage media are still functional.
Handling video recordings
If you also capture video, treat the audio track as the primary asset. Editing the video is optional; the essential steps are to label the file with the same naming convention used for audio and to back it up using the 3‑2‑1 rule. Store the video in a widely supported container such as MP4 with H.264 video and AAC audio, which balances quality and file size. Even if you never edit the footage, having a correctly labeled and backed‑up copy ensures the visual context remains available for future reference.
Worth remembering: Focus on a minimal, high‑quality audio chain, control the room’s acoustics, set levels before you speak, and follow a disciplined naming and backup routine. These steps keep family recordings clear and safe without unnecessary expense.
Common questions
What equipment is actually necessary?
A portable recorder that records 24‑bit/48 kHz PCM, two cardioid lavalier microphones, windshields, and spare batteries are sufficient. Optional gear such as mixers or shotgun mics can be added later if specific problems arise.
What settings should I use?
Record in an uncompressed WAV or AIFF format at 24‑bit/48 kHz, set input gain so peaks stay between -12 dB and -6 dB, and lock the gain before starting. Use a consistent file‑naming pattern that includes the date and participants.
How do I back up the recording safely?
Follow the 3‑2‑1 rule: keep three copies, store them on two different media types, and keep one copy off‑site. Verify each copy after transfer and periodically check that the off‑site storage remains accessible.
