TrackPublishOptions audioBitrate Setting

[rsmithclearspeed]

Describe the bug

The documentation here indicates that it is possible to set the audioBitrate parameter directly via the TrackPublishOptions input type. However, the published type does not appear to have this field.

Is it currently possible to directly configure the bitrate via the Javascript SDK?

Reproduction

Attempting to set the bitrate as shown in the example from the documentation (see below code snippet) returns the following Typescript error: Object literal may only specify known properties, and 'audioBitrate' does not exist in type 'TrackPublishOptions'.

const localParticipant = useLocalParticipant();

const audioTrack = await createLocalAudioTrack({
  channelCount: 2,
  echoCancellation: false,
  noiseSuppression: false,
});
const audioPublication = await localParticipant.publishTrack(audioTrack, {
  audioBitrate: 510000,
  dtx: false,
  red: false,
});

@rsmithclearspeed In the example you linked, the property is audioPreset, not audioBitrate - here are the options the SDK provides:

client-sdk-js/src/room/track/options.ts

Lines 448 to 467 in 3bea46a

	export namespace AudioPresets {
	export const telephone: AudioPreset = {
	maxBitrate: 12_000,
	};
	export const speech: AudioPreset = {
	maxBitrate: 24_000,
	};
	export const music: AudioPreset = {
	maxBitrate: 48_000,
	};
	export const musicStereo: AudioPreset = {
	maxBitrate: 64_000,
	};
	export const musicHighQuality: AudioPreset = {
	maxBitrate: 96_000,
	};
	export const musicHighQualityStereo: AudioPreset = {
	maxBitrate: 128_000,
	};
	}

Would one of those presets work for your use case?

If not, you might be able to set the bitrate manually with something like the below:

const localParticipant = useLocalParticipant();

const audioTrack = await createLocalAudioTrack({
  channelCount: 2,
  echoCancellation: false,
  noiseSuppression: false,
});
const audioPublication = await localParticipant.publishTrack(audioTrack, {
  // Use a preset:
  // audioPreset: AudioPresets.musicHighQualityStereo,

  // Or (maybe) set it manually:
  audioPreset: {
    maxBitrate: 510_000,
  },

  dtx: false,
  red: false,
});
