What does "silence threshold" under Silence Detection do?

[Phuntso]

To get my silence detector to relaunch the playback if internet drops in my case, I randomly whacked it to some four digit negative number and It worked. But what does it actually do?

It's trying to work out things based on the actual audio data values being received instead of using something that's doing smarter analysis of the audio data (something I need to get around to doing but the simpler mode was decent enough when I made the plug-in which was then merged into the wacup core). Depending on what else might be going on, a zero check might be enough or it needs to be changed with the extreme top/low values being more there if something weird is going on but if it's working for your setup then I'd just stick with it tbqh.
