About Audio Trimmer
Audio Trimmer cuts a clip between start and end times so you keep only the segment you need.
Upload the file, set start and end in seconds, and download the result. The on-page player helps you hear duration before you cut.
Works entirely in the browser for supported formats - useful on machines where you cannot install an audio editor.
Example workflow
Select a recording and enter the start and end in seconds. To keep a clip from 10 to 25 seconds, set those two values and review the downloaded WAV.
Output checks and limits
Browser audio decoding depends on codec support and device memory. Trimming reduces duration; WAV can still be larger than a compressed source such as MP3.
