High Fidelity and Stereo Audio

For scenarios like live music, karaoke, podcasts, or professional streaming, you may want to deliver audio that sounds natural and unprocessed. Our SDK provides APIs that let you tune the audio pipeline for higher fidelity. External high-quality microphones are also supported.

HiFi Mode

The fastest way to enable high-quality audio is by turning on HiFi mode. This is an all-in-one switch that does three things under the hood:

1. Enables stereo capture – your app will record and transmit two channels instead of mono.
2. Studio quality bitrate – switches to a high-quality music bitrate.
3. Disables audio processing – echo cancellation, noise suppression, and automatic gain control are turned off.

Allow HiFi audio on the call type

HiFi audio is allowed by default on the livestream call type.

You can enable it on other call types by toggling the Allow HiFi audio setting in the call type settings. This setting is available in the Stream Dashboard, under Video & Audio > Call Types > [call type] > Settings > Allow HiFi audio

Microphone Hi-Fi mode

import { SfuModels } from "@stream-io/video-client";

await call.microphone.setAudioBitrateProfile(
  SfuModels.AudioBitrateProfile.MUSIC_HIGH_QUALITY,
);
