I've uploaded the ReadSource/MonoReader merge, as well as some fixes in the 
AudioReader classes.
A ReadSource no longer has a Peak object, I've moved that to AudioClip, which 
solves the recursion problem a bit nicer, though it's a bit crashing now and 
then on program exit :-( (might be related, maybe not)

Old projects don't work now, but the performance increase for reading stereo 
audio files is certainly worth it!
Specially for the compressed file types, reading a stereo flac has about ~ 
0.67 % cpu load now here, vs ~ 1.1 % before

A converter is planned to convert old project files to make them work again!

Yeah, it works quite well now actually! I've loaded files with different 
samplerates, changed the audiodevice samplerate to different rates, it all 
plays back like it should, wonderfull!
Thanks a lot!
Of course it takes some cpu to do samplerate conversion on the fly, I've done 
a little profiling, and 98% of the cpu was spend in src, no opportunity for 
optimizations there I'm afraid, the simplest one is using a lower quality 
resampling :)

I've been playing flac files for hours now, and it's certainly more stable 
then with libsndfile! No random crashes or pops and crackles...
Finally!

I owe you at least 3 beers :D
