Aec

gemini_adk_fluent_rs::voice::dsp::aec

Struct Aec 

Source 
pub struct Aec { /* private fields */ }
Expand description

Partitioned-block frequency-domain NLMS acoustic echo canceller. See the module docs for the algorithm and its stated limits.

Implementations§

Source§

impl Aec

Source

pub fn new(config: AecConfig, sample_rate: u32) -> (Self, AecFarEnd)

Build the canceller and its paired far-end feed handle. sample_rate must match the AudioBus this stage will be run on.

Source

pub fn erle_db(&self) -> f32

Echo Return Loss Enhancement, in dB: 10·log10(EWMA(mic power) / EWMA(error power)), measured only over blocks where the far-end was active. 0.0 before any far-end activity has ever been observed — there is nothing yet to report a ratio over.

Trait Implementations§

fn process(&mut self, bus: &mut AudioBus<'_>)

fn latency_samples(&self) -> usize
