Struct NonRtResampler

pub struct NonRtResampler<T: Sample> { /* private fields */ }

An easy to use resampler for use in non-realtime applications.

Implementations

impl<T: Sample> NonRtResampler<T>

pub fn new( in_sample_rate: u32, out_sample_rate: u32, num_channels: usize, quality: ResampleQuality, ) -> Self

Create a new non-realtime resampler.

• in_sample_rate - The sample rate of the input stream.
• out_sample_rate - The sample rate of the output stream.
• num_channels - The number of channels.
• interleaved - If you are planning to use NonRtResampler::process_interleaved, set this to true. Otherwise you can set this to false to save a bit of memory.
• quality - The quality of the resampling algorithm.

Panics

Panics if:

• in_sample_rate == 0
• out_sample_rate == 0
• num_channels == 0,

pub fn from_custom(resampler: impl Into<ResamplerType<T>>) -> Self

Create a new non-realtime resampler using the given rubato resampler.

Panics

Panics if max_out_frames == 0.

pub fn num_channels(&self) -> NonZeroUsize

Get the number of channels this resampler is configured for.

pub fn reset(&mut self)

Reset the resampler state and clear all internal buffers.

pub fn process_interleaved( &mut self, input: &[T], on_processed: impl FnMut(&[T]), is_last_packet: bool, )

Resample the given input data.

• input - The input data in interleaved format.
• on_processed - Called whenever there is new resampled data. This data is in interleaved format.
• is_last_packet - Whether or not this is the last (or only) packet of data that will be resampled. This ensures that any leftover samples in the internal resampler are flushed to the output.

Note, this method is NOT realtime-safe.

pub fn process<Vin: AsRef<[T]>>( &mut self, input: &[Vin], on_processed: impl FnMut(&[Vec<T>], usize), is_last_packet: bool, )

Resample the given input data.

• input - The input data.
• on_processed - Called whenever there is new resampled data. The first argument is the buffers containing the new data, and the second argument is the length of the new data in frames (NOTE, the second argument may be less than the length of the Vecs in the first argument).
• is_last_packet - Whether or not this is the last (or only) packet of data that will be resampled. This ensures that any leftover samples in the internal resampler are flushed to the output.

Note, this method is NOT realtime-safe.

pub fn resampler_type(&self) -> &ResamplerType<T>

pub fn resampler_type_mut(&mut self) -> &mut ResamplerType<T>

Trait Implementations

impl<T: Sample> Into<ResamplerType<T>> for NonRtResampler<T>

fn into(self) -> ResamplerType<T>

Converts this type into the (usually inferred) input type.
