Editing a Recording

Split

Select an event on the timeline (or leave nothing selected to target the audio track), position the playhead where you want the cut, then click Split — or press Ctrl/Cmd + B. The event or audio clip is divided into two independent pieces at that point.

Remove Silences

Sparked Viz highlights detected gaps of silence in the audio waveform. Click Remove silence to cut every highlighted gap out of the recording at once, shortening its total length. The button is disabled once there's nothing left to remove.
