Description PRABIN KUMAR DATTA 2011-05-03 23:43:12 UTC 
Spec URL: http://prabindatta.fedorapeople.org/SPECS/vo-amrwbenc.spec 
SRPM URL: http://prabindatta.fedorapeople.org/SRPMS/vo-amrwbenc-0.1.0-1.fc14.src.rpm
Description: 
This library contains an encoder implementation of the Adaptive 
Multi Rate Wideband (AMR-WB) audio codec. The library is based 
on a codec implementation by VisualOn as part of the Stagefright 
framework from the Google Android project.

Comment 2 Mohamed El Morabity 2011-05-03 23:59:25 UTC 
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 2011-05-04 01:48:48 UTC 
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.
