Struct Resampler 

pub struct Resampler { /* private fields */ }

Audio resampler that accepts interleaved f32 samples.

Internally buffers partial chunks and drives rubato’s fixed-input-size resampler, producing interleaved f32 output.

Implementations

impl Resampler

pub fn new( from_rate: u32, to_rate: u32, channels: usize, quality: Quality, ) -> Result<Self>

Create a new resampler.

• from_rate / to_rate — input / output sample rates in Hz.
• channels — number of interleaved channels (must be >= 1).
• quality — algorithm selection (see Quality).

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

Feed interleaved f32 samples and receive resampled interleaved output.

Input length must be a multiple of channels. Output length will also be a multiple of channels.

The resampler buffers internally, so output may be shorter or longer than a naive ratio calculation — call flush at the end to drain remaining samples.

pub fn flush(&mut self) -> Result<Vec<f32>>

Flush remaining buffered samples by zero-padding to a full chunk.

Call this once after the last process() call to retrieve the tail of the resampled signal.

pub fn output_frames_estimate(&self, input_frames: usize) -> usize

Estimate the number of output frames for a given number of input frames.

pub fn from_rate(&self) -> u32

Get the input sample rate.

pub fn to_rate(&self) -> u32

Get the output sample rate.

pub fn channels(&self) -> usize

Get the number of channels.

pub fn reset(&mut self)

Reset the resampler state and clear all internal buffers.
