Make the cut deliberate.

03 / Listen and compare

The same region, two ways.

Stopped

Use a comfortable device volume. Playback stops when the tab is hidden, settings change or a file is downloaded. Software playback status does not confirm speaker audibility.

04 / Keep the result

A new file, not an overwritten source.

16-bit PCM WAV at the decoded sample rate. Browser decoding may resample the input. No MP3 export, editable project backup or original metadata preservation. Keep the original file separately.

Know what was saved.

First sample is inclusive; the end is exclusive. Source start rounds up and end rounds down to sample boundaries. Fades round to sample counts. Clipped values are counted before they are clamped to the PCM range.
