pub struct Resampler<'a> { /* private fields */ }

Implementations

impl<'a> Resampler<'a>

pub fn new( input_rate: usize, output_rate: usize, coeffs: &'a mut [f32], ) -> Result<Self, CodecError>

Create a new Resampler, writing polyphase filter coefficients into the caller-provided buffer.

coeffs.len() must be at least COEFFS_LEN (= 6144 floats, ~24 KB). The buffer is held by the resampler for its entire lifetime; it is written once here and read on every subsequent resample_into call.

pub fn input_rate(&self) -> usize

pub fn output_rate(&self) -> usize

pub fn resample_into( &mut self, input: &[Sample], out: &mut [Sample], ) -> Result<usize, CodecError>

Resample input into the caller-provided out buffer.

Returns the number of samples written. Returns CodecError::BufferTooSmall if out cannot hold the result; use Self::max_output_samples to size it.

pub fn max_output_samples(&self, n_input: usize) -> usize

Upper bound on the number of samples resample_into will produce for an input of n_input samples.

pub fn resample(&mut self, input: &[Sample]) -> PcmBuf

Convenience wrapper that allocates a Vec and calls resample_into.

pub fn reset(&mut self)
