Description:

liba52 is a free library for decoding ATSC A/52 streams.
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.
