mkv : Matroska file
MKV (Matroska video File) is a video container format that supports more than one audio and subtitle tracks at the same file. It is based on Extensible Binary Meta Language. It supports several video and audio compression formats. The difference between MKV file types with most other video extensions is that it is a container, not a codec.
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.
