Detailed Description

The DFOscillator object implements generates a very pure sinusoidal oscillator by placing poles direclty on the unit circle. Accuracy is excellent even at low frequencies.

Audio I/O:

• Output only object: pitched audio sinusoidal generator.

Control I/F:

• Use OscillatorParameters structure to get/set object params.
