Cut a piece out of an audio file

Drag the two ends, keep the middle. Nothing is re-encoded, so the piece you get is identical to the original.

What this tool does

Almost every recording has a beginning nobody needs: two minutes of people arriving, the microphone being adjusted, the «can you hear me?». And usually an end just as useless. Cutting that off isn't editing — it's the thing you do before doing anything else with the file, and it shouldn't require installing an audio editor.

This one doesn't re-encode: it copies the piece you marked, byte for byte, into a new file of the same format. That means two things. It's instant, even on a two-hour recording, because there's nothing to compute. And it's lossless — the cut piece sounds exactly like it did inside the original, which is not true of a trimmer that decodes and re-encodes on the way through.

What we handle that others don't

  • It copies instead of re-encoding: the cut is instant and loses nothing at all.
  • The output keeps the original format — an MP3 comes out an MP3, a WAV a WAV — so nothing downstream has to be told anything new.
  • A player right there, so you can find the exact moment instead of guessing at numbers.
  • Nothing is uploaded. A two-hour recording is cut without a single megabyte crossing the network.

How it works

  1. 1

    Drop the audio

    It loads into the player below so you can listen and find the spot.

  2. 2

    Mark the piece

    Drag the two ends of the bar. The length you've selected is shown in the middle.

  3. 3

    Download the cut

    Same format, same quality, just shorter. It takes a second.

In detail

Copying instead of re-encoding, and why it matters

Almost every trimmer out there does three things: decode the whole file, keep the piece you marked, and compress it again. The result sounds slightly worse than the original — a second compression always leaves a mark — and it takes as long as the computer needs to chew through the entire recording.

This one decodes nothing. It finds where your piece begins, copies the data as-is until where it ends, and writes it into a new file in the same format. That's why it's instant even on a two-hour recording, and why the cut sounds exactly as it did inside the original: it's the same bytes.

Trimming before transcribing pays for itself

Transcription is billed by the minute, and the first ten of a meeting are usually people arriving, a microphone being adjusted and two rounds of «can you hear me?». That's ten minutes you pay for and then have to scroll past.

Cutting them before you upload is the cheapest thing you can do to a recording, and it improves what comes back: the model doesn't have to decide what to make of five minutes of room noise, and the summary doesn't have to ignore it. A ten-second trim here saves minutes of quota there.
