Struct FirFilter 

pub struct FirFilter {
    pub coefficients: Vec<f32>,
    /* private fields */
}

Finite Impulse Response filter.

Fields

coefficients: Vec<f32>

Filter coefficients (impulse response).

Implementations

impl FirFilter

pub fn new(coefficients: Vec<f32>) -> Self

pub fn process(&mut self, buffer: &mut [f32])

In-place block processing.

pub fn reset(&mut self)

Reset the delay line.

pub fn num_taps(&self) -> usize

Number of taps.

pub fn group_delay(&self) -> f32

Group delay in samples (for a linear-phase FIR: (N-1)/2).
