Convert nist to sxw

What is the difference between .nist and .sxw?

Description: 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.; The SXW file format is associated with StarOffice Writer, a word processing application that was part of the StarOffice suite developed by Sun Microsystems. The SXW file type was primarily used to save text documents that could include formatted text, images, tables, and other document elements. StarOffice served as a precursor to the more widely known OpenOffice.org suite, which later evolved into Apache OpenOffice and LibreOffice, among others.
