## Detailed Description

This section explains how to configure audio and video codecs.

The client is able to encode audio in Speex and OPUS format whereas video can be encoded in WebM format. OPUS is recommended for audio encoding, both for voice and music.

Choosing the right codec settings in an end-user application is very important and proper settings depend entirely on the user scenario. Always ensure that the codec settings do not require too much bandwidth and thereby resulting in packetloss causing inaudible conversations and poor video quality. Detecting packetloss can be done using BearWare.UserStatistics and BearWare.ClientStatistics.

Every channel must configure which audio codec to use in order for users to be able to talk to each other. The audiocodec member of BearWare.Channel specifies which audio codec (BearWare.AudioCodec) should be used. A channel does not restrict the video codec (BearWare.VideoCodec) users are using.
