EncodedAudioChunk: type property

Available in workers

The type read-only property of the EncodedAudioChunk interface returns a value indicating whether the audio chunk is a key chunk, which does not relying on other frames for decoding.

Value

A string, one of:

• "key"
  • : The data is a key chunk.
• "delta"
  • : The data is not a key chunk.

Examples

In the following example the type is printed to the console.

const init = {
  type: "key",
  data: audioBuffer,
  timestamp: 23000000,
  duration: 2000000,
};
const chunk = new EncodedAudioChunk(init);

console.log(chunk.type); // "key"
