![]() ![]() ![]() Ī commercial implementation of both LC AAC and HE AAC, Nero AAC is produced by Nero AG as part of their Nero Digital line of products. The licensed encoder included with Winamp is optimized for encoding music on desktop-class processors, while the Android version includes low-delay encoding for real-time communication on embedded systems/mobile phones.Īccording to the July 2011 96kbps listening tests by IgorC, Winamp's Fraunhofer encoder is better than Nero AAC and tied with the Apple encoder (then part of QuickTime). The FDK AAC encoder included in Android.The licensed AAC encoder that is included in Winamp.Fraunhofer AAC Encoders See Fraunhofer.įraunhofer IIS develops two related AAC encoders: Libav also recommends using FDK AAC if it is available. These encoders are LGPL-licensed open-source and can be built for any platform that the FFmpeg or Libav frameworks can be built.īoth FFmpeg and Libav can use the Fraunhofer FDK AAC library via libfdk-aac, and while the FFmpeg native encoder has become stable and good enough for common use, FDK is still considered the highest quality encoder available for use with FFmpeg. Libav has not merged this work and continues to use the older version of the AAC encoder. A significant amount of work was done for the 3.0 release of FFmpeg (February 2016) to make its version usable and competitive with the rest of the AAC encoders. The native AAC encoder created in FFmpeg, and forked with Libav, was considered experimental and poor. įFmpeg/Libav native AAC encoder See Libavcodec AAC.
