The recording is scanned for silence at the threshold and gap length you set.
About this audio splitter
Drop a long recording in and the tool finds every section that's quieter than your threshold for at least the duration you set, then splits the file at those gaps. Each non-silent chunk becomes its own track.
Useful for cutting a 1-hour DJ mix into individual songs, slicing a sermon recording at the pauses, breaking an audiobook into chapters, or pulling out the spoken bits from a noisy tape.

Split by silence FAQ
What's a good silence threshold?
-30 dB works for clean recordings. Live recordings with crowd noise need -20 to -25 dB. If the tool over-splits, raise the threshold (less negative); if it misses gaps, lower it.
What's a good minimum gap?
1-2 seconds for music tracks separated by silence. 3-5 seconds for sermons / audiobook chapters. Lower than 0.5 s and you'll catch breath pauses.
Can I get a single ZIP of all parts?
Right now each part is a separate download. Let us know if you want a ZIP option added.
Are the splits exact at the silence?
The tool detects the start/end of each silent region and cuts at those boundaries. The cuts are sample-accurate.
