About Codecs
Audio codecs describe the format by which audio streams are compressed for transmission ov er networks.
Codecs can be categorized as either narrowband or wideband:
• Narrowband codecs work with low bandwidth such as a dialup internet connection. These codecs have a
sampling rate of 8 kHz.
• Wideband codecs work with hi gh bandw idths and result in bette r audio qu ality. However, they do not work
with PSTN. These codecs have a sampling rate of 16 kHz.
