AOMedia Video 1 (AV1) - is an open, royalty-free high efficiency video coding format designed for video transmissions over the Internet. AV1 is more efficient than H.264, H.265, HEVC, VP8, VP9. In a comparison of AV1 against H.264 (x264) and VP9 (libvpx), AV1 showed about 45–50% bitrate savings over H.264 and about 40% over VP9 when using a constant quality encoding mode.

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.
