Struct Upsampler 

pub struct Upsampler { /* private fields */ }

Causal, zero-padded interpolation. State size depends only on the filter.

Implementations

impl Upsampler

pub fn new(factor: u32, base_rate_hz: u32) -> Result<Self, Error>

Accepts factors 4, 8, or 16 and any base rate supported by the crate. Invalid factors return Error::InvalidConfig; invalid rates return Error::InvalidInput.

pub fn process( &mut self, input: &[f32], output: &mut Vec<f32>, ) -> Result<(), Error>

Appends exactly input.len() * factor samples, retaining the causal delay. An invalid block leaves both state and output unchanged. After flush, reset first.

pub fn flush(&mut self, output: &mut Vec<f32>)

Appends 2 * delay() tail samples once; an empty stream has no tail. Samples outside the supplied stream are zero, including before its start.

pub fn delay(&self) -> usize

Exact group delay in oversampled output samples.

pub fn reset(&mut self)

Clears history and permits processing a new stream after flush.
