Soundproof

FOR UX & QUALITATIVE RESEARCH

Clean research interviews without uploading them.

Remove steady fan, HVAC, hum and hiss from Zoom recordings, voice memos, field audio and interview video. Soundproof processes the recording locally and exports a separate working copy.

WHERE IT HELPS

Rescue the interviews that are valuable but tiring to hear.

Soundproof is strongest when a participant's voice is understandable but steady environmental noise makes review harder.

REMOTE

Laptop fan and HVAC

Reduce constant room and computer noise captured during remote customer interviews.

FIELD

Recorder hum and hiss

Clean steady electronic noise in in-person interviews and portable recorder files.

REVIEW

Uneven playback loudness

Normalize spoken-word loudness so a batch of interviews is easier to review and present.

A WORKING COPY, NOT A NEW SYSTEM

Keep the research repository you already use.

Soundproof is a file utility, not a research repository, transcript editor or collaboration platform. It cleans the selected recording and returns a new file for your existing workflow.

Important: if the next step is transcription or repository upload, use a provider approved by your organization. Local cleanup does not make a later cloud step local.

FIT CHECK

Use it when the noise matches the tool.

Good candidates

  • Participant is already understandable
  • Fan, AC, hum, hiss or constant room tone
  • Long recordings that need batch cleanup
  • Video that should remain video after cleanup

Expect variable results

  • Several people talking over the participant
  • Café chatter or crowds
  • Strong room echo and reverberation
  • Clipped, distorted or missing speech

RESEARCH FAQ

Questions before you try it.

Does Soundproof transcribe interviews?

No. Soundproof focuses on local noise cleanup and loudness. It returns a cleaned audio or video file that you can review or send to an approved transcription workflow.

Can it clean a folder of interviews?

Yes. Add multiple recordings to the batch queue and process them together.

Does it overwrite the research recording?

No. Soundproof exports a separately named cleaned copy. Keep the original according to your research and retention policy.

Can it clean Zoom or Meet video?

Yes, after you export or download the recording. Soundproof accepts common Mac video formats and can replace the audio track while preserving the picture.

Is the cleaned file automatically compliant with our consent or privacy policy?

No. Soundproof keeps its cleanup step local, but your team remains responsible for consent, access, retention, sharing and every later step in the research workflow.
