Struct Denoiser 

pub struct Denoiser { /* private fields */ }

Streaming noise suppressor. Stereo uses two independent RNNoise states, one per channel (no crosstalk between channels).

See the crate-level documentation for details on latency and carry-over.

Implementations

impl Denoiser

pub fn new(channels: u16) -> Result<Denoiser, DenoiseError>

Create with a channel count (1 = mono, 2 = interleaved stereo).

pub fn process(&mut self, interleaved: &mut [f32]) -> Result<(), DenoiseError>

Apply noise suppression in place to any-length interleaved samples (normalized ±1.0, 48 kHz). Length must be a multiple of the channel count (an empty slice is a no-op).

Internally splits input into frames of FRAME_SIZE samples per channel and carries any remainder to the next call. Output is delayed by FRAME_SIZE samples per channel, with silence (0.0) at the start of the stream. Chunk boundaries do not change the output sequence. Output samples are clamped to ±1.0.

pub fn flush(&mut self) -> Vec<f32>

Zero-pad the carried remainder to one frame and process it, then return the final delayed FRAME_SIZE samples per channel as interleaved output and close the stream.

Total output is now total input + FRAME_SIZE samples per channel (initial silence padding). After this call, the denoiser returns to the same initial state as Denoiser::reset and can process a new stream.

pub fn reset(&mut self)

Reset the RNN state, carry-over buffers, and delay line.

After reset, the state matches a newly created denoiser, so the same input produces the same output.

pub fn channels(&self) -> u16

Channel count specified at construction.
