Struct CaptureHandle 

pub struct CaptureHandle { /* private fields */ }

Handle for receiving AEC-processed audio samples. Capture stops automatically when dropped (channel disconnect stops backend).

Implementations

impl CaptureHandle

pub fn new(config: AecConfig) -> Result<Self, AecError>

Create and start a new AEC capture stream. Audio samples are received via the async recv() or blocking recv_blocking() methods.

pub async fn recv(&self) -> Option<Result<Vec<f32>, AecError>>

Receive audio samples asynchronously. Returns None when the capture stream is closed.

pub fn recv_blocking(&self) -> Option<Result<Vec<f32>, AecError>>

Receive audio samples, blocking the current thread. Returns None when the capture stream is closed.

pub fn try_recv(&self) -> Option<Result<Vec<f32>, AecError>>

Try to receive audio samples without blocking. Returns None if no samples are available or stream is closed.

pub fn native_sample_rate(&self) -> u32

Get the actual sample rate being used by the backend. May differ from requested rate if resampling is active.

pub fn play_audio( &self, samples: Vec<f32>, sample_rate: u32, ) -> Result<(), AecError>

Play audio through the same engine used for capture. This enables AEC to cancel the played audio from the recording. Audio is played at the specified sample rate.

pub fn start_playback_stream( &self, sample_rate: u32, ) -> Result<PlaybackStreamHandle, AecError>

Start a streaming playback session. Returns a handle for sending audio chunks incrementally. The stream ends when the handle is dropped.
