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.
Audio file encoded in Dialogic's ADPCM (VOX) format, a format used for saving human speech audio; saves digitized voice data sampled at a low rate; enables the audio data size to be small while still maintaining clarity; used by computer telephony systems.
