Often you only want a slice of a recording — a ringtone from a song, a single quote from an interview, a clean sample from a longer take. The Audio Trimmer lets you set a start and end time and exports exactly that segment as a WAV file, with no audio software to install and nothing uploaded to a server.
How to use the Audio Trimmer
- Upload your audio file.
- Enter the start and end times in seconds.
- Click Trim.
- Download the trimmed clip.
Precise cuts without a studio
Because the tool works on the raw audio samples, the cut is sample-accurate rather than a rough approximation — what you ask for is what you get. That precision is perfect for making a ringtone of just the chorus, pulling a usable sound effect out of a recording, isolating one speaker's answer from a meeting, or removing silence and dead air from the start and end of a take.
Tips for clean trims
- Note your times first by listening through and writing down the start and end seconds.
- Leave a tiny buffer so you do not clip the first or last syllable.
- Trim from a WAV master if you plan to make several cuts, to avoid repeated compression.
- Re-trim as needed — the original file is never altered.
All processing runs locally in the Web Audio engine, so your recording stays private and the trimmed clip is ready to download the moment you click the button.
