liba52

AmigaOS4 notes:

I know that there is another a52 package on the depot, but that one
is more aimed towards codecs and it doesn't hold the libraries (.so/.a),
which i need for one of my ports.

ABOUT LIBA52

liba52 is a free library for decoding ATSC A/52 streams. It is
released under the terms of the GPL license. The A/52 standard is used
in a variety of applications, including digital television and DVD. It
is also known as AC-3.

The main goals in liba52 development are:

      *	Portability - Currently all of the code is written in C, and
	when we write platform-specific optimizations we will always
	keep a generic C routine to fall back on.

      *	Reuseability - we do not want liba52 to include any
	project-specific code, but it should still include enough
	features to be used by very diverse projects.

      *	Precision - We are trying to implement all of the A/52
	standard, and to have a very precise output by doing all the
	calculations in floating point. We have a test suite that
	detects any deviation in the output when compared to previous
	versions. We do not have access to official A/52 test vectors
	though, so we have to use our judgement to ensure that such
	deviations are only intruduced when we fix bugs !

      *	Speed - liba52 is really fast, on any modern PC it should take
	only a few percent of CPU time.
