[Sumover-tech] RAT on OS X

[Devin Jones]

Hello, I'm Devin Jones, the student working on this project.  I have  
no experience working with audio nor such complex code.  Any  
suggestions would be appreciated.  Thus far I successfully tried  
building the code on OSX 10.4.  I've also been looking at  
auddev_macosx.c and documentation on CoreAudio's Audio Hardware  
Abstraction Layer API and CoreAudioTypes.h.  Knowing what to study  
certainly helps, so, once again, any suggestions would be appreciated.
