The 3 AEC configurations are: + +* aec-disable is the default disabled state of the AEC block - the initial state + of your FCDEV3B/Caramel2/etc board if you do nothing. + +* pirelli-handheld is the AEC configuration extracted from Pirelli's firmware, + used in the handheld mode. + +* pirelli-handfree is the AEC configuration extracted from Pirelli's firmware, + used in the hands-free loudspeaker mode. + +Applying pirelli-handfree AEC config to an FCDEV3B setup with the "official" +FreeCalypso HQ loudspeaker and microphone produces noticeable improvement in +voice call quality, as perceived by the person on the far end of the call: the +delayed acoustic echo goes away, and the tester reported that my voice sounded +better too.
