In the context of LiveKit, cleanup code is essential for releasing resources properly. For example, if you're using the JavaScript SDK's

createAudioAnalyser

function, it provides a cleanup function that should be called when you're done with the audio analysis:

const { analyser, calculateVolume, cleanup } = createAudioAnalyser(track);
// Later when you're done with the audio analyzer:
await cleanup();

Similarly, in the Swift SDK, the

E2EEManager

class has a

cleanUp()

method, though specific usage details may vary. As a general best practice, cleanup functions should be called when the associated resources are no longer needed, such as during component unmounting or when the application is shutting down.
