Convert nist to voc

What is the difference between .nist and .voc?

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 VOC file format is an audio file format primarily used by Creative Technology's Sound Blaster sound cards for storing digital audio data. Developed by Creative Labs, the VOC format was widely used for storing sound samples and music files on PCs during the late 1980s and early 1990s. VOC files support mono and stereo sounds at various sampling rates and can contain multiple sound snippets and silence segments, making them versatile for a range of audio applications, including video games, sound effects, and voice.
