Convert nist to wav

What is the difference between .nist and .wav?

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.; A WAV file is an audio file that uses a standard digital audio file format utilized for storing waveform data. It allows audio recordings to be saved with different sampling rates and bitrates and is often saved in a 44.1 KHz, 16-bit, stereo format, which is the standard format used for CD audio.
