What Is Audio Trimmer?
The Audio Trimmer decodes an audio file into raw samples, keeps only the section you selected and re-encodes that section as a 16-bit WAV. Start and end points are exact numbers you can type, or set from the current playback position while you listen, so cutting a voice memo down to the useful ten seconds does not need a desktop editor. Because the cut happens on decoded samples rather than on compressed bytes, the edit point stays clean instead of landing on a partial frame.
Who Uses the Audio Trimmer?
Reviewers shorten a voice memo before sending it, producers prep a ringtone or an intro sting, and presenters trim the dead air off both ends of a recording.
How to Use the Audio Trimmer
- Choose or drop the audio file and let the duration, sample rate and channel count appear.
- Play it back while you set the start and end points, or type the timestamps directly.
- Press Trim and download the resulting WAV, checking the kept length in the stats.
