Trim silence

Cut the silent head and tail from an audio file — threshold and padding in your control.

Decoding and trimming happen in this browser. Nothing is uploaded.

How to use

  1. Choose an audio file.
  2. Set silence threshold and padding.
  3. Download the trimmed WAV.

What it supports

RMS block scan across all channels, threshold −100–0 dB, pad 0–5,000 ms; audio up to 200 MB that decodes within a 256 MB PCM budget (~12 min stereo at 44.1 kHz). Output is uncompressed WAV. Only the outer edges are cut — pauses inside the file stay.
