工作原理
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.
- 1Your file is decoded into a waveformThe 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.
- 2You drag the handles to a selectionDrag the start and end handles on the waveform (or use the fine sliders) and press play to preview just your selection before exporting.
- 3FFmpeg cuts the clipWithout 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.
- 4The trimmed clip is offered for downloadThe result is handed back as a downloadable blob and previewed with the built-in player.
Perfect for making a ringtone or clipping a podcast moment without uploading your audio to a third-party site. No queue, no watermark, no file-size limit.
