What is the difference between .divx and .nist?

Description: A DivX-Encoded Movie File, designated with the .divx file extension, is a digital video format that offers a high-quality, highly compressed viewing experience. Developed by DivX, LLC, this format is designed to compress lengthy video segments into smaller sizes without significantly sacrificing visual quality. This enables users to store and distribute high-definition videos more efficiently over limited bandwidth or storage capacities. The DivX codec, which is required to play these files, supports advanced multimedia features such as multiple video streams.; 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.
