    echo-cancel: Add alternative echo-cancellation implementation · 526277c9
    Arun Raghavan authored
    This adds Andre Adrian's AEC implementation from his intercom project
    (http://andreadrian.de/intercom/) as an alternative to the speex echo
    cancellation routines. Since the implementation was in C++ and not in
    the form of a library, I have converted the code to C and made a local
    copy of the implementation.
    
    The implementation actually works on floating point data, so we can
    tweak it to work with both integer and floating point samples (currently
    we just use S16LE).
