Struct sample::interpolate::Sinc

pub struct Sinc<S> { /* fields omitted */ }

Interpolator for sinc interpolation.

Generally accepted as one of the better sample rate converters, although it uses significantly more computation.

Methods

impl<S> Sinc<S>

fn new(frames: Fixed<S>) -> Self where
    S: SliceMut,
    S::Element: Frame, 

Create a new Sinc interpolator with the given ring buffer.

The given ring buffer should have a length twice that of the desired sinc interpolation depth.

The initial contents of the ring_buffer will act as padding for the interpolated signal.

panic!s if the given ring buffer's length is not a multiple of 2.

Trait Implementations

impl<S> Interpolator for Sinc<S> where
    S: SliceMut,
    S::Element: Frame,
    <S::Element as Frame>::Sample: Duplex<f64>, 

type Frame = S::Element

fn interpolate(&self, x: f64) -> Self::Frame

Sinc interpolation

fn next_source_frame(&mut self, source_frame: Self::Frame)

Called whenever the Interpolator value steps passed 1.0.
