Trim audio (mp3 / wav / m4a / ogg) right in your browser. Drag the start / end markers on the waveform, optionally add fade in / out, then export a standard 16-bit PCM WAV via OfflineAudioContext.

Upload an audio file (mp3 / wav / m4a / ogg) — it is decoded with AudioContext.decodeAudioData into raw samples, then drawn as a waveform. Drag anywhere on the waveform to set the start / end of the selection (or type exact seconds). Tick “Fade in / out” and pick a duration to apply a linear ramp at both edges. Preview plays just the selected range. Export renders the trimmed segment with OfflineAudioContext (applying the fades) and downloads a standard 16-bit PCM WAV file — WAV is the only widely-supported format encodable purely in the browser. Nothing is uploaded; all processing is local.
