What is ULAW?
ULAW file is known as a Audio (CCITT G.711). Standard format used in US telephony that contains raw CCITT G.711 u-law (pronounced "myoo-law") audio data; saved in an uncompressed format that can be played back by various audio programs.

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.
