Implementations

impl BiquadCoefs

pub fn new(b0: f32, b1: f32, b2: f32, a1: f32, a2: f32) -> Self

pub fn butter_lowpass(sample_rate: f32, cutoff: f32) -> BiquadCoefs

Returns settings for a Butterworth lowpass filter. Cutoff is the -3 dB point of the filter in Hz.

pub fn calc_cascaded_butter_q(order: usize, casc_idx: usize) -> f32

Returns the Q for cascading a butterworth filter:

pub fn lowpass(sample_rate: f32, q: f32, cutoff: f32) -> BiquadCoefs

Returns settings for a lowpass filter with a specific q

pub fn resonator(sample_rate: f32, center: f32, bandwidth: f32) -> BiquadCoefs

Returns settings for a constant-gain bandpass resonator. The center frequency is given in Hz. Bandwidth is the difference in Hz between -3 dB points of the filter response. The overall gain of the filter is independent of bandwidth.
