Hello, I ported g729a codec on iPhone, and you can use with jailbroke iphone. http://code.google.com/p/siphon/downloads/list http://code.google.com/p/siphon/wiki/InstallationGuideForJailbreak I have begun to release my work on: http://code.google.com/p/siphon/source/browse/#svn/trunk/g729a I think this optimization can be used on another platform and cpu. I used some assembler instructions, but it's possible to replace instructions for another cpu. Regards Samuel
