Description: A VOB file is a movie data file from a DVD disc, typically stored in the VIDEO_TS folder at the root of the DVD. It contains a majority of the data stored on the disc which includes video, audio, subtitles, DVD menus and other navigation contents. VOB files are usually formatted as MPEG-2 system streams and can be opened by various video playback programs.; 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.
