رایگان Audio Trimmer

نحوه کار

Trimming audio normally means uploading to an ad-heavy site or installing Audacity. This trimmer draws an interactive waveform in your browser and cuts the clip locally with FFmpeg.

1. 1
   Your file is decoded into a waveform

   The Web Audio API decodes the audio in your browser and we draw its waveform on a canvas — so you can see exactly where to cut. The file is never uploaded.
2. 2
   You drag the handles to a selection

   Drag the start and end handles on the waveform (or use the fine sliders) and press play to preview just your selection before exporting.
3. 3
   FFmpeg cuts the clip

   Without fades, the selection is stream-copied (-c copy) for an instant, lossless cut. Add a fade in/out and it re-encodes to apply the smooth ramp.
4. 4
   The trimmed clip is offered for download

   The result is handed back as a downloadable blob and previewed with the built-in player.
