OfflineAudioContext
The OfflineAudioContext interface inherits from BaseAudioContext.
In contrast with a standard AudioContext, it doesn't render audio to the device hardware.
Instead, it processes the audio as quickly as possible and outputs the result to an AudioBuffer.
Constructor
OfflineAudioContext(options: OfflineAudioContextOptions)
interface OfflineAudioContextOptions {
numberOfChannels: number;
length: number; // The length of the rendered AudioBuffer, in sample-frames
sampleRate: number;
}
