[App_rpt-users] Streaming questions

Mine does not sound metallic, but it does sound "fuzzy". 

But consider this: 

The basic audio in Asterisk is 16 bits x 8000 samples/sec = ~128 kb/sec

the mp3 stream is at 16 kb/sec

That's a lot of compression

If various filters and level adjustments don't help, maybe you could try
streaming at a higher rate.  If you are using a streaming provider service,
he may charge more of course ...
