About Audio Cutter
Recordings almost always carry dead weight: the two minutes of waiting before a meeting, the wrong take at the end of a voice memo, the applause you want to cut from an otherwise good recording. Audio editors can do the job, but opening one just to remove the edges of a file is a lot of ceremony for a thirty-second result.
This cutter previews the file in your browser, lets you set a start and end point, and trims the selected range on our server with FFmpeg. You choose whether the result is a compact MP3 or an uncompressed WAV, and the whole file never needs to fit the workflow: only the selected section is encoded in the output. The upload and the clip are deleted automatically after the download.
What this tool does
Preview before you cut
A browser audio player plays the selected file, so you can find the right start and end by ear instead of typing timestamps blind.
Sliders or exact seconds
Drag the two time handles to trim the edges, and the readout shows the selected length; files your browser cannot preview fall back to number fields.
MP3 or WAV output
Choose MP3 for a small file that plays anywhere or WAV for uncompressed audio that editing software imports cleanly.
Bitrate control for MP3
Pick 128 kbps for speech, 192 kbps for general listening or 320 kbps when the cut will be edited further.
Up to 15-minute clips
Each cut can be up to fifteen minutes long, which covers lectures, interviews and most podcast segments.
Temporary storage only
The uploaded audio and the cut clip live in a temporary directory and are deleted automatically after your download.
