NestedDelayAPF Class Reference

The NestedDelayAPF object implements a pair of nested Delaying APF structures. These are labled the outer and inner APFs. The outer APF's LPF and LFO may be optionally enabled. You might want to extend this object to enable and use the inner LPF and LFO as well. More...

Detailed Description

The NestedDelayAPF object implements a pair of nested Delaying APF structures. These are labled the outer and inner APFs. The outer APF's LPF and LFO may be optionally enabled. You might want to extend this object to enable and use the inner LPF and LFO as well.

Audio I/O:

• Processes mono input to mono output.

Control I/F:

• Use BiquadParameters structure to get/set object params.
