About this tool
Audio Trimmer cuts a section out of a longer recording without needing desktop editing software. In a browser it decodes the audio with Web Audio, slices the samples between your start and end seconds, and encodes the clip as WAV for download. Outside a browser it shows the trim maths instead, so you can still check exactly how long the resulting clip will be.
Frequently asked questions
Can I trim from the middle of a file?
Yes. Any start and end pair works, as long as the end is later than the start and inside the file.
What format is the trimmed clip?
WAV, encoded in the browser from the decoded audio.
