Free Online AV1 to NIST Converter

AV1 is a new open codec developed by Alliance for Open Media consisting of companies that produces electronics and develops web browsers. The codec is aimed to send high-quality videos via the internet quickly and without losing the quality even when bandwidth is low. AV1 is more efficacious then today's most popular video formats because it uses future compression technology.

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.
