Audio Trimmer

Trim audio

Drag start and end on the waveform, preview the slice, then export only what you need (or everything except the selection).

Runs in your browser. Your audio stays on this device — nothing is uploaded to BrowserSpaces for processing.

Keep or cut

Export the selection, or remove it.

Exact times

Type start/end in seconds.

Preview

Play the region before export.

Fades

Optional short fades at the edges.

Use the tool

Drag on the waveform to set the selection, or type exact times below.

How it works

Slice PCM, then encode

Selection bounds map to sample indices. Keep copies that slice; Cut concatenates the outside regions.

Three steps

  1. 1

    Open audio

    Drop a file to draw the waveform.

  2. 2

    Select

    Set start/end or drag the range.

  3. 3

    Export

    Download the trimmed clip.
