- 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 saved in the AC-3 (Dolby Digital) audio format; can include up to six channels of audio (DD 5.1 surround sound with subwoofer output); uses lossy compression and often used as the format for DVDs, cinema theaters, and game consoles.
