Drop a file

Drop a file here or choose one.

Sample workflow: drop an audio file (MP3, WAV, M4A…), set start and end, then export WAV.

Keep the middle of a voicemail or drop the silence at the ends. Output is WAV. If you promised someone an MP3, transcode elsewhere.

A voice memo that is 40 seconds of rustling plus 8 seconds of the actual address — that is this page. The engine decodes in Web Audio, slices the buffer, and writes WAV. It is not Audacity and not an MP3 encoder.

Pulling a soundtrack out of a lecture video is extract audio (MediaRecorder → often WebM). Changing the picture’s in/out points is video trimmer. Brand-new audio from the mic is voice recorder.

Email and voicemail jobs

A 40-second rustle plus eight seconds of an address is the usual cut. Output is WAV, so a clip can get heavier than a tiny AAC original. Gmail’s personal send cap is 25 MB for the whole message; MIME still adds overhead. If you promised an MP3, transcode after the slice.

How to use it

  1. Drop a file this browser can decode (what the OS codec supports).
  2. Set start and end. The slice will not start a cloud job.
  3. Download the WAV. Typical limit about 32 MB.

Honest limits

No MP3/AAC encode. No multi-track. Protected or exotic codecs may fail in the tab. This is a local utility, not a podcast studio.

FAQ

Will I get an MP3 back?

No. The cutter writes WAV (PCM). Many sites advertise MP3; this one does not.

Can I cut a video’s soundtrack here?

Extract the audio first on the extract-audio page (that export is typically WebM), then cut, or trim the video instead.

Why is the file bigger after a cut?

A compressed source decoded to WAV is uncompressed PCM. Short clips can still weigh more than a tiny AAC original.

Is the audio uploaded?

No. Decode and encode stay in this tab. About 32 MB typical ceiling.

Can I add fade or noise reduction?

No. Range slice only.
