[Consortium] Re: Linuxaudio.org consortium launch

[Dominic Mazzoni]

Looks like a neat project.  Keep in mind that Audacity is just wrapping
Olli Parviainan's excellent SoundTouch library.  For some more detailed
comparisons, you may want to download SoundTouch and try it out 
directly;
there is a newer version than the one used in the last Audacity release
and it's possible it sounds even better.  It should compile easily on 
any
Linux or Mac OS X platform.
