How to use Audio Trimmer

Pro Tips

Use the waveform zoom to get a closer view of quiet sections and dialogue boundaries for ultra-precise cuts.
Apply fade effects even to short clips-a 200ms fade can eliminate harsh clicks and pops from abrupt cuts.
Preview your entire edit before exporting to catch timing issues; playback speed can help verify fade smoothness.
For consistent results across multiple files, use batch processing mode to apply the same trim and fade settings automatically.
