Techopedia Explains Cellular Wideband Audio

Cellular wideband audio is considered to be a move toward higher definition audio. It extends the audio frequency of telephone line transmissions to a range of 50 Hz to 7 KHz and beyond. It aims to provide clearer sound quality, easy classification of closely related sounds and an overall better experience for both the talker and listener. The 3GPP has launched advanced multirate wideband (AWB) codec for implementing cellular wideband audio.
