Codec
opus
The network bandwidth necessary to send the encoded audio is typically 5~10% higher than the
Note
bit rate due to packetization overhead. For example, a two-way G.722 audio call at 64 Kbps
consumes about 135 Kbps of network bandwidth.
The corresponding attributes of the codec are listed as follows:
