Available on crate feature microphone and non-target_family=wasm only.

Implementations

impl MicrophoneBuilder

pub fn spool_dir(self, directory: impl Into<PathBuf>) -> Self

Where the bounded temporary WAV lives while recording. It holds everything the microphone hears, so use a directory only your user can read. Without one, loading creates a private per-user directory.

pub fn maximum_duration(self, maximum_duration: Duration) -> Self

The most a single recording may hold, up to about 37 hours. The spool grows with it, about 115 MB per hour, and each reader holds what it has not released, about 230 MB per hour.

pub fn open(self) -> Result<Microphone, CaptureError>

pub fn load(self) -> Result<PreparedMicrophone, CaptureError>

pub fn load_with<V>(self, vad: V) -> Result<PreparedMicrophone<V>, CaptureError>

where V: VoiceActivityDetector + Send + 'static,

Uses vad instead of the bundled Silero model, for both endpointing and the wake-word gate. A panic while it scores fails the recording in progress, or drops the held stream when idle; a panic in its reset ends the microphone.
