SilenceSkippingAudioProcessor - Improve support for skipping large periods of silence

### Searched documentation and issues

I dug through the documentation, but I did not find anything beyond the JavaDoc referencing `SilenceSkippingAudioProcessor`.

### Question

What is the intent of `SilenceSkippingAudioProcessor`? Is it to skip small portions of silence, or is it intended to be used for long periods of silence (in the minutes range)? I was hoping to use it for skipping long periods of silence, but it doesn't seem to handle such situations gracefully or correctly, if this is not it's intended usage, then my apologies, but it would be nice if it's intended usage was documented!
