Struct Resampler 

pub struct Resampler { /* private fields */ }

A band-limited converter from one sample rate to another.

Implementations

impl Resampler

pub fn new(source_rate: u32, target_rate: u32) -> Result<Self, ResampleError>

A converter from source_rate to target_rate.

Builds the whole coefficient table here, so call it off the real-time thread.

Errors

Either rate is zero or above MAX_RESAMPLE_RATE, or the source rate is more than MAX_DOWNSAMPLE_FACTOR times the target rate.

pub const fn source_rate(&self) -> u32

Source samples per second.

pub const fn target_rate(&self) -> u32

Output samples per second.

pub const fn is_identity(&self) -> bool

Whether the two rates are equal: output sample n is source sample n.

pub fn half_taps(&self) -> i64

Source samples on each side of an output sample that it weighs.

pub fn target_at_or_after(&self, source: i64) -> i64

The first output sample at or after source sample source.

pub fn target_known_before(&self, source_end: i64) -> i64

The first output sample that weighs a source sample at or after source_end: every output before it is known once the source is known up to source_end.

pub fn source_span(&self, target: Range<i64>) -> Range<i64>

The source samples outputs target weigh.

pub fn resample( &self, input: &[f32], input_start: i64, target_start: i64, output: &mut [f32], )

Writes outputs target_start .. into output from input, whose first sample is source sample input_start. The source is silent outside input.
