Class

AudioBufferSource

This source can be used to add audio data from an AudioBuffer to the output track. This is useful when working with the Web Audio API.

Extends: AudioSource

Constructor

constructor(
	encodingConfig: AudioEncodingConfig,
): AudioBufferSource;

Creates a new AudioBufferSource whose AudioBuffer instances are encoded according to the specified AudioEncodingConfig.

Methods

add()

add(
	audioBuffer: AudioBuffer,
): Promise<void>;

Converts an AudioBuffer to audio samples, encodes them and adds them to the output. The first AudioBuffer will be played at timestamp 0, and any subsequent AudioBuffer will have a timestamp equal to the total duration of all previous AudioBuffers.

Returns: A Promise that resolves once the output is ready to receive more samples. You should await this Promise to respect writer and encoder backpressure.
