Struct Denoiser 

pub struct Denoiser { /* private fields */ }

RNNoise-based noise suppressor.

Wraps nnnoiseless::DenoiseState with frame buffering to handle arbitrary input chunk sizes. Automatically resamples to/from 48kHz when the input sample rate differs.

Implementations

impl Denoiser

pub fn new(sample_rate: u32) -> Self

Create a new denoiser.

Arguments

• sample_rate - Input sample rate in Hz. Common values: 16000, 48000.

If the sample rate is not 48kHz, the denoiser will automatically resample to 48kHz for processing and back to the original rate.

Panics

Panics if resamplers cannot be created (should not happen with valid rates).

pub fn sample_rate(&self) -> u32

Returns the sample rate this denoiser was configured for.

pub fn is_resampling(&self) -> bool

Returns true if resampling is being used.

pub fn process(&mut self, samples: &[i16]) -> Vec<i16>

Process audio samples through the noise suppressor.

Input samples are i16 values at the configured sample rate. Returns denoised samples at the same sample rate. Due to frame buffering (and resampling if applicable), output length may differ from input length.

pub fn process_aligned(&mut self, samples: &[i16]) -> Vec<i16>

Process a complete buffer of samples (must be multiple of FRAME_SIZE).

This is more efficient when you know your input is frame-aligned.

pub fn reset(&mut self)

Reset the denoiser state.

pub fn buffered_samples(&self) -> usize

Returns the number of samples currently buffered.
