What is CASoundLab2?

CASoundLab2 is a Cocoa sample that demonstrates low-level access to Core Audio at the Harware Abstraction Layer (HAL).  CASoundLab2 implements a very simple tone generator capable of sine, square, and sawtooth waveforms of varying amplitudes and phases.

Note:  There are more efficient ways to implement multiple waveforms using the AudioUnit framework.  Watch for a new version of this sample coming soon.  Also, this sample makes poor use of the Cocoa multiple-document architecture.  You can open multiple windows but they all use the same waveform parameters.  Not too exciting.
