Common mistakes
- Entering an end time that's less than or equal to the start time.The 'Cut audio' button stays disabled if the end isn't greater than the start; adjust both values so the range has a positive duration.
- Not knowing the exact second where the desired fragment starts.Play the audio in the player at the top and watch the elapsed time, or try approximate values and adjust after listening to the result.
- Entering a start time greater than the audio's total duration.The tool validates that the range makes sense for the loaded file's duration and shows an error if the start is out of range.
