RemoteMeeting uses the OPUS audio codec.
It is an audio codec that is highly used on the web and it became an Internet standard.
It offers a better overall performance than the existing audio codec and has a very high compression rate.
As the latency (delay time) is very short, it is suitable for use in real-time video conferences such as real-time calls.
The wide frequency band allows users to experience better sound quality compared to other voice codecs.
