About Trim Audio
Use this tool to cut a section out of a longer recording: the intro of a song, one answer from an interview, or a single clip from a meeting. You enter a start and an end time and get just that part back as an MP3.
When it helps
- Clipping the chorus of a song to share or use as a notification sound
- Pulling a single quote out of an interview or podcast recording
- Removing dead air before a voice memo really starts
- Extracting the audio for one scene from an MP4 or WebM file
Tips
- Times can be written as 00:01:05 (hours:minutes:seconds) or as plain seconds like 65. Decimals such as 12.5 work for finer cuts.
- Leave the end field empty to keep everything from the start time to the end of the file.
- Play the original in a media player first and note the exact times; it saves trial and error.
- The output is re-encoded to MP3 at the bitrate slider value, so use 192 kbps or higher if the clip is music.
