Soundproof

PRIVATE AUDIO CLEANUP FOR MAC

Clean confidential interviews. Skip the cloud.

Soundproof removes fan, AC, hum and hiss from audio and video entirely on your Mac. Your recording is not uploaded, and the original file stays untouched.

BUILT FOR SENSITIVE WORK

When “just upload it” is not an acceptable workflow.

Soundproof is designed for teams that need a clearer working copy without adding an audio-processing vendor to the path of the recording.

01 · RESEARCH

Customer and research interviews

Clean NDA-covered product interviews, field recordings and recorded calls before review or transcription.

02 · PEOPLE

HR and internal conversations

Improve steady-noise problems in working copies of employee interviews and internal investigations.

03 · EDITORIAL

Journalism and documentary work

Keep source interviews on the reporter's Mac while preparing clearer audio or video for editorial review.

ONE CONTROLLED WORKFLOW

From noisy source to review-ready copy.

No transcription tab, cloud library or new collaboration system to adopt.

01

Drop in files or a folder

Accepts common audio formats plus MP4, MOV and M4V. Batch a set of interviews in one queue.

02

Listen before exporting

A/B preview the cleanup and hold to hear the original. Adjust strength when a lighter touch is better.

03

Export a separate copy

Soundproof denoises, gates, compresses and levels loudness, then saves a new cleaned file without overwriting the source.

MEASURED, NOT MAGICAL

Strong on steady noise. Honest about the rest.

Independent workflows need predictable claims. Soundproof publishes its objective SI-SDR tests—including the weak case—so teams can decide whether a recording is a good fit before they buy.

Best for: ventilation, laptop fans, mains hum, hiss and constant room tone. Results vary: background voices, crowds, interruptions and strong room echo.

Noise typeGain at hard 5 dB SNR
Mains hum+10.0 to +13.3 dB
Hiss+10.9 to +12.3 dB
Fan / room noise+8.6 to +10.2 dB
Background voices−0.2 to +3.4 dB

TRUST, IN PLAIN ENGLISH

Know exactly where the recording goes.

Local processing is one part of a responsible workflow. We document the app's file handling, network behavior and support boundaries for reviewers and procurement teams.

No audio-processing cloud

The bundled model runs on the Mac. Soundproof does not receive, store, inspect or train on recordings processed in the app.

Separate purchase traffic

Payment and entitlement providers process purchase information. The recording is not included in activation or restoration checks.

Support is opt-in

Support receives a recording only if someone deliberately attaches it to an email. Sensitive recordings should not be sent for support.

BEFORE YOU CHOOSE IT

Important boundaries.

Soundproof reduces noise in a new working copy. It is not a compliance certification or a forensic evidence tool.

What Soundproof can establish

  • Recording cleanup is performed locally
  • The source file is not overwritten
  • No recording is sent during purchase activation
  • The app can be tested with Wi-Fi off

What depends on your organization

  • Mac login, disk encryption and access controls
  • Retention, consent and deletion policy
  • Whether a cleaned copy is appropriate for the use case
  • Regulatory or evidentiary requirements

QUESTIONS

Business FAQ.

Does Soundproof claim to be HIPAA or GDPR compliant?

No. Compliance applies to an organization's full technical and administrative workflow, not to a noise-removal feature in isolation. Soundproof documents its local-processing design so your organization can evaluate it.

Can we verify that cleaning works offline?

Yes. The model is bundled with the app and recording cleanup works with Wi-Fi turned off. A purchase or restoration may need a separate online entitlement check.

Does Soundproof change the original recording?

No. It exports a separately named cleaned copy. For evidentiary or regulated material, retain the original and follow your organization's rules for derivative files.

Can several people use one purchase?

An individual license is for one person. Teams can request a multi-seat quote and invoice from the team licensing page.

Does it remove other people speaking in the background?

Sometimes, but not reliably. Soundproof is strongest on steady noise such as fan, AC, hum and hiss. Background speech and room echo may remain.
