Struct BiquadFilter 

pub struct BiquadFilter { /* private fields */ }

A per-channel RBJ biquad filter Processor.

Implementations

impl BiquadFilter

pub fn new(kind: BiquadKind, frequency_hz: f32, q: f32) -> Self

Creates a biquad filter of the given kind, frequency, and Q (clamped to >= 0.05).

pub fn low_pass(frequency_hz: f32, q: f32) -> Self

Creates a low-pass biquad at the given frequency and Q.

pub fn high_pass(frequency_hz: f32, q: f32) -> Self

Creates a high-pass biquad at the given frequency and Q.

pub fn band_pass(frequency_hz: f32, q: f32) -> Self

Creates a band-pass biquad at the given frequency and Q.

pub fn notch(frequency_hz: f32, q: f32) -> Self

Creates a notch biquad at the given frequency and Q.
