Hi, When Google released the code for Android Gingerbread in December, they released source code for two new Apache 2.0 licensed audio encoders provided by VisualOn, for AAC and AMR-WB.
These encoders are now wrapped up in standalone encoder libraries, vo-aacenc and vo-amrwbenc, just as for opencore-amr (which included an AMR-NB encoder and decoder, and an AMR-WB decoder) before. These projects, while not sharing any code with opencore-amr, are quite similar in their heritage and style (being a standalone wrapping of codecs from another framework), and are hosted under the opencore-amr sourceforge project for now. The release files are available at https://sourceforge.net/projects/opencore-amr/files/, and the code is available in git at git://opencore-amr.git.sourceforge.net/gitroot/opencore-amr/vo-aacenc and git://opencore-amr.git.sourceforge.net/gitroot/opencore-amr/vo-amrwbenc respectively. The same code is also available on github, at https://github.com/mstorsjo/vo-aacenc and https://github.com/mstorsjo/vo-amrwbenc for easier collaboration. The vo-amrwbenc library provides a very minimal interface similar to what the old, unredistributable libamrwb used, so any code that used that library can easily be adapted to use vo-amrwbenc instead. The vo-aacenc library, on the other hand, directly exposes the VisualOn audio codec interface. Both libraries come with an optional example program showing how to use their interfaces. The code in these libraries are (just as for opencore-amr) relicensed versions of 3GPP reference code, but all of it has, to the best of my knowledge, been checked for legal correctness by Google. In addition to the original reference code, they also contain some optimizations for ARM, initially done by VisualOn, and further improved by Mans Rullgard.
