GUIDE

How to trim an audio clip accurately

Audio trimming removes silence, extracts an interview section, or makes a notification sound. This tool uses seconds and re-encodes the clip, avoiding unplayable cuts across incompatible containers.

MP3 is convenient for sharing, while WAV suits editing. Re-encoding can introduce tiny sample differences at cut points; use a desktop audio workstation for mastering.
