Silence Remover
Drop a file. We find the actual audio and trim the dead air at the start and end automatically. Adjust the threshold if your recording is noisier than usual.

MP3, WAV, M4A, FLAC, OGG, AAC. Drop several for batch.
How it works
We scan the file from the start, looking for the first sample loud enough to cross the threshold you picked. Then we scan from the end backwards, looking for the last loud sample. Everything between is kept, plus a small padding so the audio doesn't start mid-syllable.
Picking the threshold
A quiet home studio recording has a noise floor around -55 to -65 dBFS. A phone recording in a normal room is closer to -45 dB. If the tool cuts too much, raise the threshold (less negative). If it leaves obvious silence in, lower it (more negative).
What it doesn't do
This trims leading and trailing silence. We don't yet remove silence between phrases (that's a different operation — destructive editing, harder to get right without artifacts). For now, use this to get a clean entry and exit, then layer with our cutter if you need surgical edits.
