inherited
vad_config_default(Pointer<VADConfig> config_out) → void: Create default VAD configuration for Silero VAD @param config_out Pointer to VADConfig struct to fill with default values
vad_create() → Pointer<VADHandle>: Create a new VAD instance @return Pointer to new VAD handle, or NULL on failure
vad_destroy(Pointer<VADHandle> handle) → void: Destroy a VAD instance and free resources @param handle VAD handle to destroy
vad_float_to_pcm16(Pointer<Float> float_samples, Pointer<Int16> pcm16_samples, int sample_count) → void: Convert float32 audio samples to PCM16 @param float_samples Input float32 samples (-1.0 to 1.0) @param pcm16_samples Output PCM16 buffer (must be allocated) @param sample_count Number of samples
vad_force_end_speech(Pointer<VADHandle> handle) → void: Force end current speech segment if any @param handle VAD handle
vad_get_last_error(Pointer<VADHandle> handle) → Pointer<Char>: Get the last error message @param handle VAD handle @return Error message string (do not free)
vad_init(Pointer<VADHandle> handle, Pointer<VADConfig> config, Pointer<Char> model_path) → int: Initialize VAD with configuration and model @param handle VAD handle @param config Pointer to VAD configuration @param model_path Path to ONNX model file (can be NULL for bundled model) @return 0 on success, negative error code on failure
vad_invalidate_callback(Pointer<VADHandle> handle) → void: Invalidate the callback to prevent it from being invoked This MUST be called before closing the Dart NativeCallable to prevent crashes. Uses synchronous dispatch to ensure all pending callbacks complete first. @param handle VAD handle
vad_is_speaking(Pointer<VADHandle> handle) → int: Check if VAD is currently detecting speech @param handle VAD handle @return 1 if speech is being detected, 0 otherwise

vad_process_audio(Pointer<VADHandle> handle, Pointer<Float> samples, int sample_count) → int: Process audio samples directly (without microphone capture) Use this when you have your own audio source @param handle VAD handle @param samples Pointer to float32 audio samples (normalized -1.0 to 1.0) @param sample_count Number of samples @return 0 on success, negative error code on failure
vad_reset(Pointer<VADHandle> handle) → void: Reset VAD state (clear buffers and speech detection state) @param handle VAD handle
vad_set_callback(Pointer<VADHandle> handle, VADEventCallback callback, Pointer<Void> user_data) → void: Set the event callback for VAD events @param handle VAD handle @param callback Event callback function @param user_data User data passed to callback
vad_start(Pointer<VADHandle> handle) → int: Start audio capture and VAD processing @param handle VAD handle @return 0 on success, negative error code on failure
vad_stop(Pointer<VADHandle> handle) → void: Stop audio capture and VAD processing @param handle VAD handle
