I can't seem to find a thread on this subject, but I suspect it's been discussed before.
A lot of audio archives for those not-so-busy feeds are mostly full of recorded silence. I doubt this has a huge impact on the size of the compressed audio files on the server, but it sure makes trying to weed out a short communication on such a feed challenging.
Has anyone on the server side of things looked into "voice activated" recordings, so the silence in between received transmissions is reduced to just X seconds?
I'm not a code jockey, but I'd be happy to help research a solution. I also have any necessary test equipment here to work with specific audio levels to help with testing, although I think both implementation and testing would be mostly done with software.
