Struct Oversampler

pub struct Oversampler { /* private fields */ }

Expand description

One-channel configurable 1x/2x/4x/8x streaming f32 oversampling. Three fixed half-band stages and stack scratch require no preparation heap. Changing factor requires a new instance/reset; no live crossfade, dry-path alignment or constant integer latency is supplied. Closure DSP must be prepared at host sample rate times factor and obey callback obligations.

Implementations§

impl Oversampler

pub fn new(factor: OversamplingFactor) -> Self

pub fn factor(&self) -> OversamplingFactor

pub fn reset(&mut self)

pub fn process_sample( &mut self, input: f32, process: impl FnMut(f32) -> f32, ) -> f32

Upsample in time order, invoke DSP once per high-rate sample, then decimate in time order. The closure is called exactly factor times.
