Struct Interpolator 

pub struct Interpolator { /* private fields */ }

Band-limited interpolation for clips at non-unity speed, using the same kernel as Resampler at any real source position.

Faster than unity, the cutoff falls to the output Nyquist and the filter widens so content above it is removed rather than aliased; slower, the source Nyquist bounds it. Weights come from one libm table, interpolated linearly and summed in a fixed order, so output is bit-identical natively and in wasm.

Implementations

impl Interpolator

pub fn new(speed: f64) -> Self

The filter for speed source samples per output sample; invalid speeds use unity.

pub const fn half_taps(&self) -> i64

Source samples weighed on each side: a position whole + fraction reads whole - half + 1 ..= whole + half.

pub fn weights(&self, fraction: f64, weights: &mut Vec<f64>)

Writes the 2 * half normalized weights for a position fraction (in 0..1) past a source sample.

Trait Implementations

impl Clone for Interpolator

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Interpolator

impl Debug for Interpolator

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
