# warmAudioPlayer

URL: https://www.caprid.com/docs/reference/typescript/caprid/moq-media/functions/warmaudioplayer/

```ts
function warmAudioPlayer(context, options?): Promise<void>;
```

Defined in: [audio-player.ts:359](https://github.com/caprids/relay-sdks/blob/main/ts/packages/moq-media/src/audio-player.ts#L359)

Start loading what [createAudioPlayer](https://www.caprid.com/docs/reference/typescript/caprid/moq-media/functions/createaudioplayer/) waits for, both at once: the jitter buffer's worklet module on `context`
and, with loss concealment, the libopus WebAssembly module. A player created on the context later finds them loaded
or loading, and loads neither again. Call it as soon as the context exists, for example while the connection or the
catalog is on its way, so a join does not wait for them after the catalog. Resolves once both are ready; rejects
only when the worklet module fails (without libopus a player decodes with WebCodecs, as `createAudioPlayer` does).
Optional: a player created without it loads both itself, as before.
