Defaults Configuration

await DyteClient.init({
defaults: {

While initializing DyteClient you can pass configuration overrides, the available options are

type DefaultOptions {
video?: boolean;
audio?: boolean;
screenShare?: {
displaySurface?: 'window' | 'monitor' | 'browser';
mediaConfiguration?: {
video?: VideoQualityConstraints,
audio?: AudioQualityConstraints,
isNonPreferredDevice?: (device: MediaDeviceInfo) => boolean;
* If true, will automatically switch audio input and output device
* to a new device connected mid call. (In case of disconnection switch
* will happen automatically in both cases)
autoSwitchAudioDevice?: boolean;
recording?: RecordingConfig;


This optional propery is true by default and defines whether audioTrack would be acquired and enabled on SDK initialization


This optional propery is true by default and defines whether videoTrack would be acquired and enabled on SDK initialization


Specifies the preferred screenshare surface, user will still be shown all possible options but the one configured here will be preselected


Defines media quality configuration

For audio -

echoCancellation?: boolean, // default true
noiseSupression?: boolean, // default true
autoGainControl?: boolean, // default true
enableStereo?: boolean, // default false
enableHighBitrate?: boolean // default false

For applications where audio quality needs to be high and as loseless as possible

echoCancellation: false,
noiseSupression: false,
autoGainControl: false,
enableStereo: true,
enableHighBitrate: true,

For video -

width: { ideal: number },
height: { ideal: number },
frameRate?: { ideal: number },


Our SDK will acquire media devices preferring virtual devices to not be selected by default (OBS, iPhone continuity) You can override this logic by using your own function to decide the preference

defaults: {
isNonPreferredDevice: (device: MediaDeviceInfo) => {
if(device.label.startsWith("Virtual")) {
return false


By default, when a new audio device is plugged in our SDK switches to that device. You can configure that behaviour


fileNamePrefix?: string;
videoConfig?: {
height?: number;
width?: number;
codec?: string;

Refer to recording codec guide for info the codec parameter
