Description: The High Efficiency Video Coding (HEVC) file, commonly known by its file extension .hevc, represents a video compression format designed to substantially improve coding efficiency compared to its predecessor, H.264/AVC. Aimed at enabling higher resolution video content such as 4K and 8K, HEVC is adept at maintaining high-quality video at roughly half the bitrate, significantly reducing file sizes without compromising on visual fidelity. This efficiency makes HEVC particularly valuable in streaming media applications.; 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.
