Expand description

Filter parameters for the filters crate::fh_va::Svf, crate::fh_va::SallenKey and crate::fh_va::LadderFilter.

Fields

cutoff: f32

Cutoff frequency 5.0 Hz to 20 kHz.

res: f32

Resonance, values between 0.0-1.0, default: 0.5

drive: f32

Filter drive, values between 1.0 and 15.8490 (gain to dB)

mode: SvfMode

The SVF filter mode.

ladder_mode: LadderMode

The Ladder filter mode.

g: f32

Calculated by the FilterParams::set_frequency function.

sample_rate: f32

Use the FilterParams::set_sample_rate function to update this.

zeta: f32

Resistance based internal parameter, set by FilterParams::set_resonance.

k_ladder: f32

Resistance based internal parameter, set by FilterParams::set_resonance.
