What is mpegaudio

mpegaudio is a simple mpeg encoder/decoder that does LayerI&II audio encoding/decoding. It is provided mainly for developers, and people who do not have an mpeg encoder. For a better quality implementation, you really should look at the IRIS dmedia tools. Silicon Graphics' Audio Library contains compression schemes for mpeg audio as well as aiff, wav, afic, and sun u-law. The mpeg audio encoder can be purchased directly from Silicon Graphics. Call your sales office for more information.

This distribution comes with two programs, musicin, and musicout, which converts from and to mpeg audio, respectively. to use, please see the README files provided in /usr/freeware/info/mpegaudio/.
