    hi
    i need help with my project
    my project must do the following

    Automatic processing for realtime audio(human voice) with microcontroller (must eliminate noise ,feedback and echo,distribute sound equally over speakers )


    {not intersting to store the signal so the memory is not important }
    my instructor said that i dont need DSP because we dont need that whole processing and that microcontrololler will be enough for the project .

    so what microcontroller do what i want

    details:
    there will be several microphones at different position

    only the microphone that detect the strongest signal will enabled
    and not to take signal from the others

    the sound must processed automatically with microcontroller (not DSP )
    to eliminate echo from speakers and suppressed noise.

    notes
    microphones & speakers are wire and wireless

    can u help me with my project ...i want to understand it more .
    any recommended microcontrollers ,topics, software,hardware
    that would be great

    if u know some projects similiar to this to get benifit from plz help

    As you've been told before. You want a microcontroller with a DSP.
    It's one of those things that if you have to ask you're probably in way over your head.
    Since it's a school project your instructor should have something in mind.
