Trim Audio at a Precise Time: How to Fill Start/End
Explains the start/end time formats (seconds / mm:ss / hh:mm:ss) for trimming audio and common caveats.
Time can be plain seconds (e.g. 30), mm:ss (e.g. 1:30 for 1 min 30 s), or hh:mm:ss (e.g. 0:01:30).
Start must be less than end, and both must fall within the audio duration, or the trim will fail.
After uploading, the tool reads the duration and defaults the end time to the end of the audio — you only need to change the start.
