It is a free library for decoding ATSC A/52 streams, aka AC-3. The
|
|
A/52 standard is used in a variety of applications, e.g., digital
|
|
television and DVD. The main goals in liba52 development are:
|
|
|
|
Portability - most of the code is written in C, and when we use
|
|
platform-specific optimizations we always have 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.
