This CL performs a major refactoring and simplification of the AudioBuffer code that. -Removes 7 of the 9 internal buffers of the AudioBuffer. -Avoids the implicit copying required to keep the internal buffers in sync. -Removes all code relating to handling of fixed-point sample data in the AudioBuffer. -Changes the naming of the class methods to reflect that only floating point is handled. -Corrects some bugs in the code. -Extends the handling of internal downmixing to be more generic.
