When to use Audio trimmer
Save a selected audio interval
Enter start and end times within the decoded recording. Output samples cover that interval in PCM WAV.
Remove an unwanted introduction
Set the start after the introduction and keep the desired ending. The tool does not detect silence or speech automatically.
Review the uncompressed output
WAV can be larger than an MP3 or OGG source. It preserves the decoded samples at 16-bit output precision.
