Create an exact length of pure digital silence — for padding out a track, testing an app's audio handling, or as a placeholder clip.
The Silence Generator creates a file of pure digital silence of any length from 10 milliseconds to an hour. Use it to pad recordings, fill gaps in video edits, create spacer tracks for CD burning, meet minimum-length upload rules or make placeholders.
Choose the sample rate and mono or stereo so the silence matches the rest of your project exactly.
Silence is a buffer of zero-valued samples: duration × sample rate samples per channel. A 16-bit stereo WAV uses 4 bytes per sample frame plus a 44-byte header. Note that constant-bitrate MP3 does not shrink silence — frames are fixed-size, so a minute of silence is still about 1 MB at 128 kbps — and MP3 encoders add a short delay and padding, so use WAV when the length must be exact.
Fill gaps with exact-length silence.
Make spacer tracks.
Satisfy minimum duration.
Add a pause between segments.

Yes — all samples are zero.
About 635 MB as 16-bit 44.1 kHz stereo WAV.
Common uses: padding the start/end of a track to an exact length, inserting a deliberate pause between tracks in a playlist, or testing how software handles empty audio.
