AUDIO_PROCESSING_CHANNELS

Number of channels for audio preprocessing.

In scenarios such as concerts where enhanced realism is required, local users may need to capture and send stereo signals to remote users. For example, on a concert stage, the lead singer, guitarist, and drummer stand in different positions. The on-site equipment captures stereo sound from all three and sends the stereo signal to remote users, allowing them to hear vocals, guitar, and drums from different directions as if they were on stage. With this class, you can set dual-channel processing to achieve stereo. It is recommended to configure it as follows:
  1. Preprocessing: Call SetAdvancedAudioOptions and set audioProcessingChannels in AdvancedAudioOptions to AUDIO_PROCESSING_STEREO (2).
  2. Postprocessing: Call SetAudioProfile [2/2] and set profile to AUDIO_PROFILE_MUSIC_STANDARD_STEREO (3) or AUDIO_PROFILE_MUSIC_HIGH_QUALITY_STEREO (5).
Note:
  • Stereo settings only take effect under media volume.
To understand the difference between media volume and call volume.
