What is 3GP2?
3GPP and 3GPP2 are the new worldwide standards for the creation, delivery and playback of multimedia over 3rd generation, high-speed wireless networks. Defined by the 3rd Generation Partnership Project and 3rd Generation Partnership Project 2 respectively, these standards seek to provide uniform delivery of rich multimedia over newly evolved, broadband mobile networks (3rd generation networks) to the latest multimedia-enabled wireless devices. 3GPP and 3GPP2 are based on the MPEG-4 standard which was derived from Apple's QuickTime. QuickTime 6.5 includes support for key components of the 3GPP and 3GPP2 specifications.

The 3GP and 3G2 file formats are both structurally based on the ISO base media file format defined in ISO/IEC 14496-12 - MPEG-4 Part 12, but older versions of the 3GP file format did not use some of its features. 3GP and 3G2 are a container formats similar to MPEG-4 Part 14 (MP4), which is also based on MPEG-4 Part 12. The 3GP and 3G2 file format were designed to decrease storage and bandwidth requirements in order to accommodate mobile phones.

What is AWB?
Adaptive Multi-Rate Wideband (AMR-WB) is a patented speech coding standard developed based on Adaptive Multi-Rate encoding, using similar methodology as Algebraic Code Excited Linear Prediction (ACELP). AMR-WB provides excellent speech quality due to a wider speech bandwidth of 50-7000 Hz compared to narrowband speech coders which in general are optimized for POTS wireline quality of 300-3400 Hz.

AMR-WB is codified as G.722.2, an ITU-T standard speech codec, formally known as Wideband coding of speech at around 16 kbit/s using Adaptive Multi-Rate Wideband (AMR-WB). G.722.2 AMR-WB is the same codec as the 3GPP AMR-WB. The corresponding 3GPP specifications are TS 26.190 for the speech codec and TS 26.194 for the Voice Activity Detector.

A common file extension for AMR-WB file format is .awb. There also exists another storage format for AMR-WB that is suitable for applications with more advanced demands on the storage format, like random access or synchronization with video. This format is the 3GPP-specified 3GP container format based on ISO base media file format. 3GP also allows use of AMR-WB bit streams for stereo sound.

The AMR-WB bitrates are 6.60, 8.85, 12.65, 14.25, 15.85, 18.25, 19.85, 23.05 and 23.85 kbps. Compared to narrowband speech codecs (like AMR) optimized for traditional telephone voice quality of 300-3400 Hz, the AMR-WB codec's wider bandwidth of 50-7000 Hz provides excellent speech quality.
