sph : SPeech HEader Resources

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.

aac : Advanced Audio Coding

AAC is an audio file format that works similar to MP3 but compresses more than MP3. It significantly reduces the audio file size without losing the quality. To reduce the file size it uses the MPEG-4 standard to cut off the low frequency sounds that cannot be heard in a human’s ear.
