Silence threshold (dBFS)Quieter than this counts as silence (-70–-15)Shortest pause to cut (s)Shorter pauses stay (0.1–5)Pause kept next to sound (s)Kept on each side (0.02–0.5)

Detection looks at loudness in 10 ms windows and treats a moment as silent only when every channel is below the threshold. Very quiet speech, breaths and soft music fades can sit below the threshold and be cut, so preview before applying.

Preview the cuts, then apply them to create a new WAV.

Decoding and loudness run in the built-in FFmpeg engine; pause analysis runs in a background worker. The original file is never changed.

Good to know

Memory limitsUp to 5 minutes, 50 MB and two channels per file, because the whole recording is decoded into browser memory (about 115 MB for 5 minutes of stereo).

Quiet speech and musicA fixed threshold cannot tell a soft voice or a fade from silence. Lower the threshold for quiet recordings and check the red regions.
