Designing Audio Effects Plugins in C++ 2nd Ed.
- Chapter 13 Modulators: LFOs and Envelope Detectors
Description:
- implements a 2nd order resonant modulated LPF using the MMA LPF2 algorithm
- uses signal detection in dB and measures distances above threshold in dB
Notes:
- try changing the filter type to a BPF or a Reson filter for more of a wah-wah sound
- add a HPF in the side-chain to prevent aggressive bass frequencies from triggering the filter accidentally – especially important for guitar effects
