How to Cut Audio to Exact Seconds

Our audio trimmer provides multiple ways to set precise cut points:

  • Waveform drag handles — drag the start and end handles on the waveform for visual precision
  • Slider controls — use the start and end time sliders for 0.1-second precision
  • Keyboard shortcuts — nudge handles by 0.1s (arrow keys) or 1s (Shift + arrow keys)
  • Preview mode — hear exactly what will be exported before downloading

The time display shows hours:minutes:seconds.tenths format, so you can set cut points to the nearest 0.1 second.

Keyboard Shortcuts for Precise Cutting

For maximum precision, use keyboard shortcuts while previewing:
