Designing Audio Effects Plugins in C++ 2nd Ed.
- Chapter 11 Audio Filter Designs: Wave Digital and Virtual Analog
Description:
- implements the four, ideal 2nd RLC filters for LPF, HPF, BPF and BSF
- not like other WDF implementations because these require zero source impedance and infinite load impedance
- see the book above for many more details including the frequency “de-warping” that I implement
Notes:
- uses the WDF Ladder Filter Library and a separate interface specifically designed for WDFs
