The EncodedAudioChunk() constructor creates a new EncodedAudioChunk object representing a chunk of encoded audio.
new EncodedAudioChunk(options)
options
An object containing the following members:
type
Indicates if the chunk is a key chunk that does not rely on other frames for encoding. One of:
"key"
The data is a key chunk.
"delta"
The data is not a key chunk.
timestamp
An integer representing the timestamp of the audio in microseconds.
duration
An integer representing the length of the audio in microseconds.
data
An ArrayBuffer, a TypedArray, or a DataView containing the audio data.
transfer
An array of ArrayBuffers that EncodedAudioChunk will detach and take ownership of. If the array contains the ArrayBuffer backing data, EncodedAudioChunk will use that buffer directly instead of copying from it.
In the following example a new EncodedAudioChunk is created.
const init = {
type: "key",
data: audioBuffer,
timestamp: 23000000,
duration: 2000000,
transfer: [audioBuffer],
};
chunk = new EncodedAudioChunk(init);
