CustomAudioTrackConfig enum

Defines audio quality presets for microphone audio tracks.

• These presets control audio bitrate, channel configuration, and overall sound quality.

Encoder Config Reference

Encoder Config	Bitrate	Auto Gain	Echo Cancellation	Noise Suppression
speech_low_quality	16 kbps	TRUE	TRUE	TRUE
speech_standard	24 kbps	TRUE	TRUE	TRUE
music_standard	32 kbps	FALSE	FALSE	FALSE
standard_stereo	64 kbps	FALSE	FALSE	FALSE
high_quality	128 kbps	FALSE	TRUE	FALSE
high_quality_stereo	192 kbps	FALSE	FALSE	FALSE

Note: If you face issues related to echo, you can use noiseConfig with echoCancellation: true. Echo cancellation attempts to prevent echo effects on a two-way audio connection by reducing or eliminating crosstalk between the user's output device and their input device — for example, filtering out sound produced by the speakers from being captured by the microphone input track.

Example

final audioTrack = await VideoSDK.createMicrophoneAudioTrack(
  encoderConfig: CustomAudioTrackConfig.high_quality,
);
