AudioWorkletGlobalScope class abstract

The AudioWorkletGlobalScope of the Web Audio API represents a global execution context for user-supplied code, which defines custom AudioWorkletProcessor-derived classes.

Each BaseAudioContext has a single AudioWorklet available under the BaseAudioContext.audioWorklet property, which runs its code in a single AudioWorkletGlobalScope.

As the global execution context is shared across the current BaseAudioContext, it's possible to define any other variables and perform any actions allowed in worklets — apart from defining AudioWorkletProcessor derived classes.

Properties

currentFrame → TauTime
The read-only currentFrame property of the AudioWorkletGlobalScope returns an integer that represents the ever-increasing current sample-frame of the audio block being processed. It is incremented by 128 (the size of a render quantum) after the processing of each audio block.
no setter
currentTime → TauTime
The read-only currentTime property of the AudioWorkletGlobalScope returns a double that represents the ever-increasing context time of the audio block being processed. It is equal to the BaseAudioContext.currentTime property of the BaseAudioContext the worklet belongs to.
no setter
hashCode → TauTime
The hash code for this object.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
sampleRate → TauSampleRate
The read-only sampleRate property of the AudioWorkletGlobalScope returns a float that represents the sample rate of the associated BaseAudioContext the worklet belongs to.
no setter

registerProcessor(String name, AudioWorkletProcessorConstructor processorCtor) → void
The registerProcessor method of the AudioWorkletGlobalScope registers a class constructor derived from AudioWorkletProcessor under a specified name.
