Struct PolyphaseResampler 

pub struct PolyphaseResampler { /* private fields */ }

Streaming windowed-sinc polyphase resampler with fixed callback state.

Construction allocates the coefficient bank and the interleaved history ring. process_interleaved writes into caller storage and performs no allocation, locking, or I/O. The filter is causal: the first output is delayed until the right half of its impulse response is available, and callers may append zero input to drain a finite stream.

Implementations

impl PolyphaseResampler

pub fn new( input_rate_hz: u32, output_rate_hz: u32, channels: usize, policy: ResamplerPolicy, ) -> Result<Self, ResampleError>

Builds a fixed-state resampler and precomputes its Blackman-windowed low-pass coefficient bank.

pub fn input_rate_hz(&self) -> u32

Returns the configured input rate in hertz.

pub fn output_rate_hz(&self) -> u32

Returns the configured output rate in hertz.

pub fn channels(&self) -> usize

Returns the interleaved channel count.

pub fn latency_input_frames(&self) -> usize

Returns the fixed source-rate latency of the causal filter.

pub fn required_output_frames( &self, input_frames: usize, ) -> Result<usize, ResampleError>

Returns the output frames that the next input block will produce.

pub fn process_interleaved( &mut self, input: &[f32], output: &mut [f32], ) -> Result<ResampleReport, ResampleError>

Consumes interleaved source frames and writes every now-available resampled frame into output.

The call fails before consuming input when the buffers are misaligned, the input bound is exceeded, or output storage is too small.

pub fn reset(&mut self)

Clears time and sample history while retaining every allocation.
