Struct Resampler 

pub struct Resampler { /* private fields */ }

Offline polyphase sinc resampler.

Construct once and reuse for any number of buffers at the same rate pair. input_rate/output_rate may be f32, f64, or integer types via the Into<f64> bounds.

use br41ndmg::Resampler;

let resampler = Resampler::new(44_100.0_f32, 48_000.0_f32)?;
let output = resampler.resample(&[0.0_f32; 512])?;

Implementations

impl Resampler

pub fn new<I, O>(input_rate: I, output_rate: O) -> Result<Self, ResampleError>

where I: Into<f64>, O: Into<f64>,

Build a resampler with the default filter parameters.

pub fn with_filter_params<I, O>( input_rate: I, output_rate: O, filter_params: PolyphaseFilterParams, ) -> Result<Self, ResampleError>

where I: Into<f64>, O: Into<f64>,

Build a resampler with a custom PolyphaseFilterParams.

pub fn input_rate(&self) -> f64

pub fn output_rate(&self) -> f64

Target sample rate in Hz.

pub fn ratio(&self) -> f64

output_rate / input_rate.

pub fn filter_params(&self) -> PolyphaseFilterParams

Snapshot of the active filter parameters.

pub fn resample_interleaved( &self, input: &[f32], channels: usize, ) -> Result<Vec<f32>, ResampleError>

Resample a mono (channels == 1) interleaved buffer.

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

Resample a mono buffer. Equivalent to resample_interleaved(input, 1).
