Support Information


The Adaptive Digital Technologies G.722.2 Audio Coder is a real-time implementation of the ITU G.722.2 audio coder also referred to as the Adaptive Multi-Rate Wideband (AMR-WB) codec. Wideband speech coding is a substantial feature in high-fidelity telephony and in telecommunications processes such as audio teleconferencing and program broadcasting.

Software Details
Codec Type Voice / Speech
Name or Standard/Profile G.722.2
Audio/Voice Sample Rate 16kHz
Supported Tools/Features G.722.2/AMR-WB provides improved speech quality due to a wider speech bandwidth of 50-7000 Hz compared to narrowband speech coders which in general are optimized for traditional POTS line quality of 300-3400 Hz. G.722.2/AMR Wide Band codec is based on the Code Excited Linear Prediction (CELP) coding model, the higher bandwidth allows the end user network to experience truer voice signals.
