Isn't AMR-WB patented? http://www.ecplaza.net/news/0/27878/voiceage_announces_the.html This may be a FE-LEGAL issue.
Comment 3 PRABIN KUMAR DATTA 2011-05-03 21:48:48 EDT
Like you I was also little bit confused at the beginning. After Googling a little bit, I found that AMR-BW/G.722.2 is patent under VoiceAge. vo-amrbw is created by VisualOn. Also, it is clearly written that "The library is based on a codec implementation by VisualOn, part of the Stagefright framework from the Google Android project." Thou, if you (or anyone else) are sure about patent thing kindly inform me.

Upstream Comment on FE-Legal issue: vo-aacenc is one library implementing an AAC encoder, libfaac is another. The patents don't cover any particular implementation - they're essential to implementing the standard and thus cover all implementations. So there can not be any implementations of AAC (nor AMR-WB) that isn't covered by patents. Copyrightwise, however, they are proper opensource, contrary to some earlier AAC and AMR-WB libraries, which were either totally unredistributable (libamr) or that have dubious origin and thus aren't considered properly redistributable either.
