The new Flash Player 10.3 (yet to be released) has a native Acoustic Echo Suppression algorithm as a feature. I have recently implemented and tested it within a Flex Audio Video chat system , and It has shown impressive results, the shrieking sounds and the echoes produced by the microphone are goneeee!
In order to implement this though you will need to have the flashplayerglobal for the 10.3 player and update your Flex HERO SDK to 4.5. You will also need to add to the ‘Additional compiler arguments’ input: -swf-version=12. You must have the 10.3 beta player installed - obviously.
For your convenience I am adding up the links to the resources I mentioned above.
Enjoy a great voice experience and Echo Less Chat :)
Will keep you posted with more interesting features!
