[Live-devel] streaming WAV files...

[Matthew Romaine]

Hi Ross,

Okay, here's the file I'm trying to stream which plays fine with a 
regular audio player but comes across the network as noise:

http://www.audiolicious.com/misc/test.wav

Also, I mixed up big / little endian -- Macs are big endian of course.  
at first I thought the fread in WAVAudioFileSource might be a culprit, 
but seems it reads in byte by byte so that should be okay....right?

only picked up your code earlier this week so am still trying to figure 
out the pipeline, but it'd be nice to be able to send even just a wav 
file....mp3 works fine though...

just a note, i'm adapting the testOnDemand -- I snipped everything out 
except the one that streams wav files; I know this only sends as 
unicast, and that is what I prefer to do for right now.

thnx,
matt
