The goal of DecMPA is to provide simple and efficient MPEG audio decoding routines, nothing more and nothing less. It does not contain any playback functionality - basically you just shove MPEG audio data in and get decoded PCM audio data out. Everything that is not directly connected with MPEG decoding is beyond the scope of this library. This also has the nice side-effect of making DecMPA highly portable because it hardly uses any operating system services at all.
