Methods

addEffect(VoiceEffect effect, {double intensity = 0.5}) → Future<void>
Add effect to processing chain
override
addListener(SintStateUpdate listener) → Disposer
Register a closure to be called when the object notifies its listeners.
inherited
addListenerId(Object? key, SintStateUpdate listener) → Disposer
inherited
applyBroadcastPreset() → Future<void>
Apply broadcast preset (podcast/radio style)
override
applyCreatorVoicePreset() → Future<void>
Apply creator voice preset (optimized for room narration)
override
applyMinimalPreset() → Future<void>
Apply minimal preset (light processing)
override
applySettings(VoiceEffectSettings newSettings) → Future<void>
Apply settings configuration
override
clearEffects() → Future<void>
Clear all effects from chain
override
clearNoiseProfile() → Future<void>
Clear learned noise profile
override
configureCompressor({double threshold = -20.0, double ratio = 4.0, double attackMs = 10.0, double releaseMs = 100.0}) → Future<void>
Configure compressor settings
override
configureDynamics(DynamicsSettings dynamicsSettings) → Future<void>
Configure dynamics settings
override
configureNoiseReduction(NoiseReductionSettings noiseSettings) → Future<void>
Configure noise reduction settings
override
configureVoiceEnhancement(VoiceEnhancementSettings enhanceSettings) → Future<void>
Configure voice enhancement settings
override
containsListener(SintStateUpdate listener) → bool
inherited
debounce<T>(RxInterface<T> rx, void callback(T), {Duration duration = const Duration(milliseconds: 400)}) → void
Calls callback after rx stops changing for duration. Useful for search-as-you-type, form validation, etc.
inherited
dispose() → void
inherited
disposeProcessor() → Future<void>
Dispose resources
ever<T>(RxInterface<T> rx, void callback(T)) → void
Calls callback every time rx changes. Auto-cancels on controller disposal.
inherited
initialize() → Future<bool>
Initialize the voice processor
override
interval<T>(RxInterface<T> rx, void callback(T), {Duration duration = const Duration(seconds: 1)}) → void
Calls callback at most once per duration, ignoring intermediate changes. Useful for rate-limiting UI updates.
inherited
learnNoiseProfile(List<int> audioData) → Future<void>
Learn noise profile from audio segment
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
once<T>(RxInterface<T> rx, void callback(T)) → void
Calls callback only the first time rx changes, then cancels.
inherited
onClose() → void
Called before onDelete method. onClose might be used to dispose resources used by the controller. Like closing events, or streams before the controller is destroyed. Or dispose objects that can potentially create some memory leaks, like TextEditingControllers, AnimationControllers. Might be useful as well to persist some data on disk.
inherited
onDelete() → void
inherited
onInit() → void
Called immediately after the widget is allocated in memory. You might use this to initialize something for the controller.
override
onReady() → void
Called 1 frame after onInit(). It is the perfect place to enter navigation events, like snackbar, dialogs, or a new route, or async request.
inherited
onStart() → void
Called at the exact moment the widget is allocated in memory. It uses an internal "callable" type, to avoid any @overrides in subclasses. This method should be internal and is required to define the lifetime cycle of the subclass.
inherited
processAudioData(List<int> inputData) → Future<List<int>?>
Process audio data in memory
override
processFile(File inputFile, {String? outputPath}) → Future<String?>
Process an audio file and return processed file path
override
processStream(Stream<List<int>> inputStream) → Stream<List<int>>
Process audio stream (for real-time)
override
refresh() → void
inherited
refreshGroup(Object id) → void
inherited
removeEffect(VoiceEffect effect) → Future<void>
Remove effect from processing chain
override
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that the object notifies.
inherited
removeListenerId(Object id, VoidCallback listener) → void
inherited
reorderEffects(List<VoiceEffect> order) → Future<void>
Reorder effects in chain
override
reportAdd(VoidCallback disposer) → void
inherited
reportRead() → void
inherited
reset() → Future<void>
Reset all processing to defaults
override
resetPeakLevel() → void
Reset peak level
override
setClarity(double value) → Future<void>
Set voice clarity (0.0 to 1.0)
override
setCompressor(bool enabled) → Future<void>
Enable/disable compressor
override
setDeBreath(bool enabled, {double sensitivity = 0.5}) → Future<void>
Enable/disable de-breath
override
setDeEsser(bool enabled, {double threshold = 0.5}) → Future<void>
Enable/disable de-esser
override
setEnabled(bool enabled) → Future<void>
Enable/disable all processing
override
setLimiter(bool enabled, {double threshold = -1.0}) → Future<void>
Enable/disable limiter
override
setNoiseReduction(bool enabled, {double strength = 0.5}) → Future<void>
Enable/disable noise reduction
override
setPresence(double value) → Future<void>
Set voice presence/brightness (0.0 to 1.0)
override
setVoiceEnhancement(bool enabled) → Future<void>
Enable/disable voice enhancement
override
setWarmth(double value) → Future<void>
Set voice warmth (0.0 to 1.0)
override
toString() → String
A string representation of this object.
inherited
update([List<Object>? ids, bool condition = true]) → void
Notifies listeners to update the UI.
inherited
updateLevels(List<int> audioData) → void
Update level meters (call during recording/playback)

Operators
