    Hi members,

    At school i've received an assigment in which me and my classmates are to design a simple circuit for display. Of couse the more complicated and working projects will receive higher scores.
    Seeing i have just finished a sound engineering study, my idea is to make a live sound effect generator.

    How it should work is that sound needs to be amplified and/or recorded by using a small microphone.
    This microphone will be switched on via a push switch with LED indicating the status.

    The amplified signal needs to be given an effect (IC?) after which it's to be listened to live via a small speaker.
    The small PCB which I also have to produce using Eagle needs to be around 110 to 90 mm and is connected to two magnetic strips which will supply 5 volts DC.

    Being a novice could someone give me some pointers on how to start designing and maybe some ideas on components and excisting schematics to use?

    Thanks in advance

    There are a number of toys out there that do this - record a voice and play it back with an effect applied, or apply a range of effects to a megaphone output in real time. Is that what you want to make? Some reverse engineering may be a starting point.

    Yes, that's exactly it! I have been searching online though and can't really find any simple ic's that can add an effect.
    Is there maybe a specific name for these components which I can search for?
