AAC-audiocodec (geavanceerde audiocodering)<\/strong><\/p>\n

\"AAC<\/p>\n

AAC is een lossy audiocompressiemethode ontwikkeld door MPEG Group (Moving Picture Experts Group). Het werd gespecificeerd als een verdere ontwikkeling van MPEG-2 in de MPEG-2-standaard. Tijdens de ontwikkeling werd rekening gehouden met bekende zwakheden en problemen in het MP3-coderingsproces en deze werden sterk verbeterd.<\/p>\n

\"AAC<\/p>\n

Nou, de geluidskwaliteit is uitstekend. Het heeft echter een prijs en zeer weinig exploitanten van videoforums en vlogs zullen in licentiekosten investeren. Dit is waar open source-oplossingen zoals FAAC (Free Advanced Audio Codec) interessant worden. De AAC audio codec heeft het grote voordeel dat deze een (redelijk) goede stereokwaliteit kan leveren bij bitsnelheden van rond de 64 kb.<\/p>\n

Wat betreft de H.264-videocodec, zijn er verschillende profielen gedefinieerd voor de AAC-audiocodec. In dit geval echter van de International Organization for Standardization, of kortweg ISO. Ze maken het vooral voor hardwarefabrikanten gemakkelijker om deze compressiemethode te gebruiken. Hier zullen we kort de meest voorkomende profielen introduceren.<\/p>\n

Laag complexiteitsprofiel (AAC-LC)<\/p>\n

Primair ontworpen voor gemiddelde tot hoge bitsnelheden. Dit profiel is compatibel met de meeste AAC-compatibele hardware-eindapparaten. Vanwege de voordelen op het gebied van codering en decoderingseffici\u00ebntie en een betere geluidskwaliteit bij hogere bitsnelheden, is dit profiel het meest voorkomende profiel bij alle hardwarefabrikanten en leveranciers van muziekwinkels.<\/p>\n

Hoofdprofiel (Main AAC)<\/p>\n

Dit profiel is ontworpen voor lage tot gemiddelde bitsnelheden. Vanwege de veel betere coderings- en decoderingsprestaties in vergelijking met AAC-LC, is dit profiel relatief ineffici\u00ebnt. De geluidskwaliteit bij gemiddelde bitsnelheden is beter dan die van het AAC-LC-profiel, maar rechtvaardigt deze ineffici\u00ebntie op geen enkele manier.<\/p>\n

Hoog rendementprofiel (HE-AAC)<\/p>\n

Dit profiel is ook ontworpen voor lage tot gemiddelde bitsnelheden. Dankzij de technische implementatie van spectrale bandreplicatie, of kortweg SBR, biedt het echter een aanzienlijk betere kwaliteit bij zeer lage tot gemiddelde bitsnelheden dan met de andere twee profielen. Het hoge effici\u00ebntieprofiel van de AAC-audiocodec wordt voornamelijk gebruikt bij streaming. Bij hogere bitsnelheden is de geluidskwaliteit van het AAC-LC-profiel echter beter.<\/p>\n","protected":false},"excerpt":{"rendered":"
