I'm not much of a developer, but this doesn't seem like it would be that
difficult. Maybe it's harder than I think, hence no tool that I can find.
Probably noone needed this precice functionality yet. I would look for
options to assemble this from lower level components:
1] A tool that can read from an http stream and write it into a pipe
(maybe mplayer/mencoder)
2] A tool to convert the stream from the compressed format into a very
low samplerate simple to parse format that reads from that pipe and
writes to another.. (mencoder)
3] A small bash script or python or whatever floats your boat program
that takes the low samplerate, simple to parse output and detects
silences in it. If the silence is "true" silence, something as simple as
searching for a long enough string of 0-bytes is enough..
