Was ist M4A?<\/h2>\n

\"m4a\"<\/p>\n

M4A ist die Dateierweiterung f\u00fcr Audiodateien, die mit Advanced Audio Coding (AAC) codiert sind, einer verlustbehafteten Komprimierung. M4A wird oft als Nachfolger von MP3 angesehen, das urspr\u00fcnglich nicht f\u00fcr Audio, sondern f\u00fcr Layer III in MPEG 1- oder 2-Videodateien konzipiert war M4A steht f\u00fcr MPEG 4 Audio.<\/p>\n

\"M4A\"<\/p>\n

M4A ist die Dateierweiterung f\u00fcr Audiodateien, die mit Advanced Audio Coding (AAC), einer Art verlustbehafteter Komprimierung, codiert sind. M4A wird oft als Nachfolger von MP3 angesehen und war urspr\u00fcnglich nicht f\u00fcr Audio konzipiert, sondern f\u00fcr Layer III in MPEG 1- oder 2-Videodateien.M4A steht f\u00fcr MPEG 4-Audio.<\/p>\n

M4A-Dateiformat<\/p>\n

Die Dateierweiterungen M4A und MP3 werden f\u00fcr reine Audiodateien verwendet. Nur-Audio-MPEG-4-Containerdateien haben normalerweise die Dateierweiterung M4A. M4A-Dateien sind nicht gesch\u00fctzt. Gesch\u00fctzte Dateien haben normalerweise die Dateierweiterung M4P.<\/p>\n

AAC- oder M4A-Dateien haben eine bessere Qualit\u00e4t und eine kleinere Dateigr\u00f6\u00dfe als MP3-Dateien. Aufgrund einiger Verbesserungen des Formats klingen M4A-Dateien besser als MP3-Dateien, wenn sie mit der gleichen Bitrate codiert werden, wie zum Beispiel:<\/p>\n

Wahrnehmungsbasierte Komprimierung: Au\u00dferhalb des Bereichs der menschlichen Wahrnehmung k\u00f6nnen Tondaten ohne wesentliche Beeintr\u00e4chtigung der Qualit\u00e4t verloren gehen.
\nEine kleinere Sample-Blockgr\u00f6\u00dfe von 120 oder 128 Samples wird anstelle von 192 f\u00fcr wechselnde (oder transiente) Signale verwendet, was bei Bedarf feinere Details erm\u00f6glicht.
\nDie Blockgr\u00f6\u00dfe in Standbildern, 1024 oder 960, erm\u00f6glicht weniger Daten, um Teile der Musik darzustellen, die nicht die gleiche Komplexit\u00e4t im Vergleich zum 576-Sample-Block von MP3 haben.<\/p>\n","protected":false},"excerpt":{"rendered":"
