CpalRecorder

opencode_voice::audio::capture

Struct CpalRecorder 

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

Records microphone audio via cpal, always producing 16kHz mono i16 output.

Implementations§

Source§

impl CpalRecorder

Source

pub fn new(device: Option<&str>) -> Result<Self>

Creates a new recorder for the given device (or default if None).

Source

pub fn start(&mut self) -> Result<UnboundedReceiver<f32>>

Starts recording. Returns a receiver for RMS energy updates (0.0–1.0).

Source

pub fn stop(&mut self) -> Result<Vec<i16>>

Stops recording and returns all captured samples (16kHz mono i16).

Source

pub fn duration(&self) -> f64

Returns the elapsed recording duration in seconds.
