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. homepage http://liba52.sourceforge.net/ platforms darwin master_sites \ http://liba52.sourceforge.net/files/ checksums md5 caa9f5bc44232dc8aeea773fea56be80 distname ${name}dec-${version}
