This is a new library, separate from the existing fdk-aac (but built from the same upstream repo), for encoding xHE-AAC. This library has the same traits as fdk-aac; it's being distributed from Fraunhofer to Android Open Source Project, and further repackaged and distributed through opencore-amr [1] (and in a personal repo on github at [2]). It is distributed under the same license as fdk-aac. This is an initial, barebones wrapper around the library - not all features of the library are hooked up currently. In particular, do note that the wrapper currently only handles loudness in the live operating mode (single pass), where encoding is done with a single loudness level set before encoding. This may affect the dynamics of the input. The preferred and intended mode of use for the fdk-xhe-aac encoder is for it to be used in two pass mode, which handles the loudness properly. The two pass operation mode is not set up in the encoder wrapper yet, but may be added later. [1] https://sourceforge.net/projects/opencore-amr/ [2] https://github.com/mstorsjo/fdk-aac
