Good resource for understand Audio stuffs

I mentioned in this post about using 'ima4' compression to reduce CAF file size. But to be honest, I am still not very clear about how all these audio stuffs work.

This might be an old one - I found this "Audio 101 for iPhone Developers: File and Data Formats" articles (3 parts) by Ray Wenderlich really helpful and clearly explained lots of stuff. Well, still don't 100% understand everything Ray said yet, but would definitely save this page for future reference.
