How to use

  1. Upload an audio file (click or drag & drop) and wait for the waveform.
  2. Drag on the waveform to select a range, or set exact start/end times with the time inputs.
  3. Click "Preview selection" to listen; double-click the waveform to add a cut point, double-click a cut point to remove it, drag it to fine-tune.
  4. Cut points automatically build the segment list — rename, fine-tune, preview, delete and download each segment.
  5. "Export all as ZIP" downloads every segment in one archive; each segment can also be downloaded as WAV individually.
