The General (2nd-Order) block gives access to a wide variety of 2nd-order (biquad)filter algorithms along with equalization. Blend factor and slew rate modifications are common for all the stages.
The available filter types are:
- Unordered List ItemOrdered List ItemParametric
- Shelving
- General High-Pass
- General Low-Pass
- General Band-Pass
- General Band-Stop
- Butterworth Low-Pass / High-Pass
- Bessel Low-Pass / High-Pass
- Tone Control
- IIR Coefficient (direct coefficient entry)
- 1st-Order Low-Pass / High-Pass
- All-pass
- Peaking
- Notch
- Chebyshev Low-Pass / High-Pass
