What is SHN?
Shorten (SHN) is a file format optimized for compressing audio data. It is a form of data compression of files and is used to losslessly compress CD-quality audio files (44.1 kHz 16-bit stereo PCM). Shorten is no longer developed and more mature lossless audio codecs such as FLAC, MPEG-4 ALS, Monkey's Audio (APE), TTA, and WavPack (WV) have become more popular. However, Shorten remains a common format due to the large number of legally-traded concert recordings in circulation that are encoded as Shorten files. Being lossless, these files can be transcoded with the newer and more effective codecs without any loss. Shorten files use the .SHN file extension.

Since few players or media writers attempt to decompress Shorten files, a standalone decompression program is usually required to convert to a different file format that those applications can handle. It is important to note that since Shorten is a lossless format, it can be perfectly converted to any other lossless format (and back, if desired) without a decrease in audio quality.

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.
