Hi Sakharam, I see 2 potential issues with what you are doing. 1. ./opus_demo -e voip 48000 2 16 music_orig.wav testcase30.opus in above command, "16" for bits/sec seems too low. I'm no audio expert, but just cant convince myself you can get any reasonable audio data with 16 bits/sec. FYI, I was able to encode and decode with 16 bits/sec, but when I played the decode fil...

Are there many cards in this category? I'dve thought that all cards would support 44100, it being the standard that it is. Your comments however suggest experience of this problem.

Hello, If anyone is running an Icecast server that serves at least 3 separate streams each with it's own bitrate can I get a look at your config? Thanks. Dave.
