Note
The network bandwidth necessary to send the encoded audio is typically 5~10% higher than the bit rate due to pack-
etization overhead. For example, a two-way G.722 audio call at 64 Kbps consumes about 135 Kbps of network bandwidth.
The Opus codec supports various audio bandwidths, defined as follows:
Abbreviation
Audio Bandwidth
Sample Rate (Effective)
NB (narrowband)
4 kHz
8 kHz
MB (medium-band)
6 kHz
12 kHz
WB (wideband)
8 kHz
16 kHz
SWB (super-wideband)
12 kHz
24 kHz
FB (fullband)
20 kHz
48 kHz
The following table lists the audio codecs supported by each phone model:
