GSM AMR WB by IntegrIT

Audio and Voice Solutions

Product Description

GSM AMR WB is Adaptive Multi Rate Wide Band vocoder conforming the ITU-T G.722.2 recommendation. Codec provides excellent speech quality in a clean environment at low bitrates. Higher bitrates are useful in noisy conditions and in the presence of music. It can be used in a wide range of applications such as multimedia devices, visual telephony, wireless telephony, and videoconferencing products. The main features are:

• Nine coding rates in range of 6.60 to 23.85 kbps
• Sampling rate 16 kHz
• ITU G.722.2 compliance and interoperability requirements
• Kernel mode compatible

GSM AMR-WB is delivered with fully automated IntegrIT Testing Environment (ITE) for target platform based on reference ITU-T vectors set along with extended IntegrIT proprietary vectors and methods.  IntegrIT GSM AMR-WB espesially optimized for Marvell Kirkwood (ARMv5), Marvell Armada (ARMv7), Apple A5 processors.
