Die Entwickler des Multimedia-Pakets FFMpeg haben die Erstellung einer eigenen Implementierung des Decoders f\u00fcr das xHE-AAC-Audioformat (Extended High-Efficiency AAC), das im ISO\/IEC-Standard 23003-3 definiert ist, bekanntgegeben. Der xHE-AAC-Decoder wurde bereits in die Hauptcodebasis von FFMpeg aufgenommen und wird Teil des n\u00e4chsten Releases sein. Diese Implementierung kann f\u00fcr die meisten Stereo-xHE-AAC-Streams verwendet werden. Streams mit SBR, USAC und MPEG-H-Surround-Sound sowie Sprachcodierung werden derzeit noch nicht unterst\u00fctzt. Die Unterst\u00fctzung f\u00fcr USAC und SBR wird in naher Zukunft versprochen. <\/p>\n

xHE-AAC wird im Streaming von Netflix verwendet und ist Teil der Technologien des digitalen Rundfunks Digital Radio Mondiale. Der Codec zeichnet sich durch eine breite Bitratenspanne (von 12 bis 300 kbit\/s) und eine hohe Komprimierungsrate aus, bietet Wiedergabem\u00f6glichkeiten mit konstanter Lautst\u00e4rke, gew\u00e4hrleistet hohe Klarheit bei allen Lautst\u00e4rkepegeln, zus\u00e4tzliche Profile f\u00fcr das Management des dynamischen Bereichs beim H\u00f6ren in lauten Umgebungen und f\u00fcgt Metadaten hinzu, die es erm\u00f6glichen, Verlusten auf der Empfangsseite entgegenzuwirken.
