# $Id$ PortSystem 1.0 name alac_decoder version 0.1.0 categories audio maintainers nomaintainer description basic decoder for Apple Lossless Audio Codec files long_description \ This is a basic decoder for Apple Lossless Audio Codec files \ (ALAC). ALAC is a proprietary lossless audio compression scheme. \ Apple never released any documents on the format. What I provide \ here is a C implementation of a decoder, written from reverse \ engineering the file format. It turns out that most of the \ algorithms in the codec are fairly well known. ALAC uses an \ adaptive FIR prediction algorithm and stores the error values \ using a modified rice or golumb algorithm. homepage http://craz.net/programs/itunes/alac.html platforms darwin master_sites http://craz.net/programs/itunes/files/ checksums md5 f554fc11ee41a30bc5baf15a0fd07256 worksrcdir ${name} use_configure no build.target destroot { xinstall -m 555 ${worksrcpath}/alac ${destroot}${prefix}/bin xinstall -d ${destroot}${prefix}/share/doc/${name} xinstall -m 444 ${worksrcpath}/README \ ${destroot}${prefix}/share/doc/${name} } livecheck.check regex livecheck.regex "
