How to use Audio trimmer
The audio trimmer cuts a section out of a recording and saves it as an MP3 file. You set the start time in seconds and a duration from 0.1 to 3600 seconds. Any video stream is dropped, so the tool can also pull an audio clip from a video file, and it checks the file's length before cutting.
- Choose a source file. If the tool accepts multiple files, arrange them in the order you want.
- Set start time (seconds), duration (seconds).
- Run audio trimmer, review the output, then use the available copy or download controls.

Frequently asked questions
What format does the audio trimmer save in?
The trimmed clip is always encoded as MP3 and named trimmed.mp3, regardless of whether the source was WAV, MP3 or another format FFmpeg can read. Keep your original file if you need lossless audio.
Can I cut a clip from the audio of a video?
Yes. The trimmer ignores the video stream and encodes only the audio of the selected range to MP3. Enter the start time and duration in seconds just as you would for an audio file.
What happens if my start time is longer than the recording?
The tool reads the recording's duration first. If the start time is at or beyond the end, it stops and tells you the file length in seconds so you can enter a valid start.
