SimpleEnergyVAD class

Simple energy-based Voice Activity Detection Based on iOS WhisperKit's EnergyVAD implementation but simplified for real-time audio processing

Constructors

SimpleEnergyVAD({int sampleRate = 16000, double frameLength = 0.1, double energyThreshold = 0.005}): Initialize the VAD with specified parameters

energyThreshold ↔ double: Energy threshold for voice activity detection (0.0 to 1.0)
getter/setter pair
frameLength → double: Frame length in seconds
no setter
frameLengthSamples → int: Length of each analysis frame in samples
final
hashCode → int: The hash code for this object.
no setterinherited
isReady → bool: no setter
isSpeechActive → bool: Current speech activity state
no setter
onAudioBuffer ↔ void Function(List<int>)?: Optional callback for processed audio buffers
getter/setter pair
onSpeechActivity ↔ void Function(SpeechActivityEvent)?: Speech activity callback
getter/setter pair
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
sampleRate → int: Sample rate of the audio (typically 16000 Hz)
final

cleanup() → Future<void>
initialize({String? modelPath}) → Future<void>
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyTTSDidFinish() → void: Notify VAD that TTS has finished
notifyTTSWillStart() → void: Notify VAD that TTS is about to start
pause() → void: Pause VAD processing
process(List<int> audioData) → Future<VADResult>
processAudioBuffer(List<int> buffer) → void: Process an audio buffer for voice activity detection
reset() → void: Reset the VAD state
