SPHERE (SPeech HEader Resources) is a file format defined by NIST (National Institute of Standards and Technology) and is used with speech audio. SoX can read these files when they contain μ-law and PCM data. It will ignore any header information that says the data is compressed using shorten compression and will treat the data as either μ-law or PCM. This will allow SoX and the command line shorten program to be run together using pipes to encompasses the data and then pass the result to SoX for processing.

MP2 is a lossy audio compression format developed by MPEG (Moving Picture Experts Group). It is widely used for audio broadcasting, while MP3 is more common for desktop and online programs. The format is supported only by some audio players, so you may need to convert it to a more popular one like MP3.
