About this tool
Choose an audio file and set start and end times. Web Audio decodes the segment and exports it as 16-bit WAV PCM.
Common uses
- Cut a short segment from a recording or audio file.
- Create a broadly compatible WAV clip for later editing or analysis.
How to use it
- 1.Choose an audio file and wait for decoding.
- 2.Enter start and end seconds, with the end after the start.
- 3.Trim, preview the result, and download the WAV file.
Limits and notes
- The source file is limited to 80 MB, 30 minutes, and 32 channels; browser decoding determines which input formats work, and output is always WAV PCM.
Frequently asked questions
Can it export MP3 or M4A?
No. The result is always 16-bit WAV PCM; whether an input format can be decoded depends on the browser.
Is my audio uploaded?
No. The file is decoded and exported in the browser unless the page explicitly says otherwise.
