[Icecast] AACPlus Shoutcast v1.90

OK, I've organized this.

It's not possible to average 32kb/s stereo with Vorbis using VBR. 
Quality -2 stereo proeduces roughly 32 to 38kb/s which is too high for 
many modems.

I would have to use ABR, but last I tried that, it utilized too much CPU 
for my 950Mhz PC, and oddcast doesn't appear to support that option 

I've tried AACPlus 32kb/s mono and there is very little difference from 
stereo as far as sound quality goes.

Anyway, I've set up a mono AAC+ stream at 32kb/s for.  It's strange that 
Winamp reports it as stereo but the selection in the the shoutcast DSP 
is mono.

Vorbis q -2   http://soulfm.stationplaylist.com/listen.m3u
AAC+ 32kb/s http://stream.gottabelieve.org:9000/soulfm.aac.m3u

I think the treble is much more natural with AAC.

Happy comparisons.

You should do stereo and then do an aacplus stream at 32kbps along side, 
can compare the two objectively.

I should have provided a link to my low bitrate vorbis stream.  It's a
mostly easy listening world music format:
