FAQ

Why can't I trim audio in Audacity?

If you came across that Audacity’s Trim Audio option greyed out, it’s usually because you didn’t or failed to select any portion. Make sure you selected audio by clicking and dragging on the blue waveform but not the timeline.

If you can play and select the audio but cannot trim, the reason might be you are in PAUSE mode. Please get the audio in STOP mode to trim audio then.
