Den betydelige \u00e6ndring i versionsnummeret skyldes overgangen af koden fra copyleft-licensen LGPLv2 til den permissive licens zlib, som er kompatibel med GPL. Derudover, p\u00e5 trods af at bagudkompatibiliteten p\u00e5 API-niveau er bevaret, kan SDL_sound nu kun fungere p\u00e5 basis af SDL 2.0-versionen (underst\u00f8ttelsen af bygninger ovenp\u00e5 SDL 1.2 er oph\u00f8rt).    <\/p>\n<p>SDL_sound bruger ikke eksterne biblioteker til dekodning af lydformater \u2014 alle n\u00f8dvendige kildekoder til dekodning er inkluderet i hovedpakken. Det tilladte API giver adgang til lyddata fra b\u00e5de filer og lydstreams fra en eller flere eksterne kilder. Det er muligt at tilf\u00f8je egne h\u00e5ndterere til lydbehandling eller give adgang til de resulterende dekodede data. Der kan udf\u00f8res forskellige manipulationer med samplingfrekvenser, formater og lydkanaler, herunder on-the-fly konvertering.    <\/p>\n<p>De v\u00e6sentlige \u00e6ndringer i SDL_sound 2.0:  <\/p>\n<ul>\n<li class=\"l\"> \u00c6ndring af licens til zlib og overgang til brug af SDL 2.\n<li class=\"l\"> Fjernelse af eksterne afh\u00e6ngigheder fra koden og indbygning af alle dekodere i den prim\u00e6re samling. Nogle dekodere er erstattet med ensartede behandlere. For eksempel kr\u00e6ver arbejdet med OGG-formatet ikke l\u00e6ngere installation af biblioteket libogg, da dekoderen stb_vorbis nu er indbygget i SDL_sound's kildekoder.\n<li class=\"l\"> Overgang til anvendelse af bygge-systemet CMake. Forenkling af processen til at bruge SDL_sound-koden i egne projekter.\n<li class=\"l\"> Oph\u00f8r af underst\u00f8ttelsen af dekoderen til det for\u00e6ldede QuickTime-format, men i macOS og iOS kan den universelle CoreAudio-dekoder stadig bruges til at arbejde med QuickTime.\n<li class=\"l\"> Oph\u00f8r af underst\u00f8ttelsen af Speex-formatet, p\u00e5 grund af manglende implementering af dekoderen under den n\u00f8dvendige licens.\n<li class=\"l\"> Oph\u00f8r af underst\u00f8ttelsen af MikMod-dekoderen. For at arbejde med de samme formater kan modplug-dekoderen bruges.    <\/ul>\n<p>Kilde: <a content=\"nofollow\" rel=\"nofollow\"
