How to use it
- Open the recording. The waveform shows quiet sections as a thin line, which is usually the part to trim.
- Type the In and Out times, or drag the yellow handles. Times accept 1:23.456, 83.456, 250ms or a sample count like 44100f.
- Press Trim (T) to keep the selection.
- Or use Silence → Trim start and end to find the first and last sound automatically using a threshold you choose.
- Export WAV to keep full quality.
Typed times and frames
Every boundary can be typed. The In and Out boxes accept minutes:seconds.milliseconds, plain seconds, milliseconds, or a raw sample frame count. The length box updates as you type, and the exact sample number of each edge is shown below it, which is useful when you must match another tool exactly.
Automatic start/end trimming
The Silence panel measures the recording in 10 ms windows and treats anything below the threshold (default −45 dBFS) as silence. Trim start and end removes only leading and trailing silence, keeping a short pad (default 80 ms) so words do not start abruptly. If your recording has hiss, raise the threshold a few dB until the detected regions look right on the waveform before applying.
Questions
What is the difference between trimming and cutting?
Trimming keeps a range and discards both ends. Cutting (Delete) removes a range from the middle and closes the gap. Both are in the toolbar and both can be undone.
Will trimming a WAV change its quality?
Not when you export WAV at the same bit depth and sample rate: the samples are copied unchanged. The 16-bit export of a 24-bit source is rounded to 16 bits.
Can I trim several files with the same settings?
Yes. Open them all, then use the Batch panel to apply the same start, end and fades to every file and download a ZIP.
