Struct idsp::hbf::HbfInt

pub struct HbfInt<'a, T, const M: usize, const N: usize> { /* private fields */ }

Half band interpolator (interpolation rate 2)

The effective number of DSP taps is 4*M - 1.

M: number of taps N: state size: N = 2*M - 1 + input.len()

Implementations

impl<'a, T: Copy + Zero + Add + Mul<Output = T> + Sum, const M: usize, const N: usize> HbfInt<'a, T, M, N>

pub fn new(taps: &'a [T; M]) -> Self

Non-zero (odd) taps from oldest to one-before-center. Normalized such that center tap is 1.

pub fn buf_mut(&mut self) -> &mut [T]

Obtain a mutable reference to the input items buffer space
