AAC- en MP3-audiokwaliteit<\/h2>\n

\"Advanced<\/p>\n

Het AAC-formaat is ontworpen om MP3 op de volgende manieren te verbeteren:<\/p>\n

\"Advanced<\/p>\n

Meer samplefrequenties (8 kHz tot 96 kHz) dan MP3 (16 kHz tot 48 kHz)
\nMaximaal 48 kanalen (MP3 ondersteunt maximaal twee kanalen in MPEG-1-modus en maximaal 5.1 kanalen in MPEG-2-modus)
\nWillekeurige bitsnelheid en variabele framelengte. Constante bitsnelheid genormaliseerd met bitbank.
\nEffici\u00ebntere en eenvoudigere filterbanken (AAC gebruikt pure MDCT in plaats van hybride MP3-codering)
\nEffici\u00ebntere codering voor stilstaande signalen (AAC gebruikt een blokgrootte van 1024 of 960 samples, wat effici\u00ebnter is dan het 576-sampleblok van MP3)
\nHogere coderingsnauwkeurigheid voor transi\u00ebnte signalen (AAC gebruikt een 128- of 120-sample-blokgrootte, waardoor een nauwkeurigere codering mogelijk is dan het 192-sample-blok van MP3)
\nSpectrale lekkage kan worden verwijderd met behulp van een van Kaiser-Bessel afgeleide vensterfunctie, maar dit gaat ten koste van de uitbreiding van de hoofdlob
\nBetere audioverwerking boven 16 kHz
\nFlexibelere gezamenlijke stereo (verschillende methoden kunnen worden gebruikt in verschillende frequentiebereiken)
\nExtra modules (tools) toegevoegd om de compressie-effici\u00ebntie te verbeteren: TNS, achterwaartse voorspelling, PNS, enz. Deze modules kunnen worden gecombineerd om verschillende coderingsprofielen te vormen.<\/p>\n

Over het algemeen geeft het AAC-formaat ontwikkelaars meer flexibiliteit bij het ontwerpen van codecs dan MP3 en kan het veel van de ontwerpkeuzes corrigeren die zijn gemaakt in de oorspronkelijke MPEG-1-audiospecificatie. Deze grotere flexibiliteit resulteert over het algemeen in meer gelijktijdige coderingsstrategie\u00ebn en dus effici\u00ebntere compressie.<\/p>\n

De MP3-specificatie, hoewel verouderd, is ondanks de vele gebreken verrassend robuust gebleken. AAC en HE-AAC presteren beter dan MP3 bij lage bitsnelheden (meestal minder dan 128 kb\/s). Dit is vooral het geval bij extreem lage bitsnelheden, waar uitstekende stereocodering, pure MDCT en meer ideale conversievensters ervoor zorgen dat MP3 niet kan concurreren. Naarmate de bitsnelheid toeneemt, wordt de effici\u00ebntie van het audioformaat echter minder belangrijk in verhouding tot de effici\u00ebntie die door de encoder wordt bereikt, en de inherente voordelen van AAC ten opzichte van MP3 domineren niet langer.<\/p>\n","protected":false},"excerpt":{"rendered":"
