Audio censor & bleep

Mute or bleep out parts of a recording

Play the clip, drag across the waveform to mark each moment you want gone, a name, an address, a number, then mute it or drop a bleep over it. Everything happens on your device, and the rest of the recording is left exactly as it was.

Runs entirely in your browser. Your file is never uploaded or stored.

How to use it

Press play and follow the waveform to find the moment you want to remove, then drag across that stretch to mark it. Add as many regions as you need; each one shows its start and end time and can be removed. Choose whether a marked region is silenced or covered with a bleep, then apply. Mute is cleaner for background detail; a bleep signals on purpose that something was taken out.

Cut cleanly, and check it back

Each region is faded in and out over a few milliseconds so the edit does not click. The preview player lets you listen to the result before you download it, so you can confirm the right words are gone and nothing important was clipped.

Download in any format

After you apply, download the censored result as lossless WAV or FLAC (nothing re-compressed) or as a smaller MP3, M4A or Opus. M4A and Opus are offered only when your browser can create them, so the list matches what your machine actually supports: keep the quality, or keep the size down.
