I'm trying to simulate this circuit in multisim for a project in my circuits course. http://hackaweek.com/hacks/?p=283
I need help with the electret microphone part. My multisim does not have any microphones in it but we are can substitute any parts we want (like a variable resistor instead if it would prove the rest of the circuit works).
Anyone know a component that could substitute an electret microphone?
I see the electret microphone is its own little circuit, (http://en.wikipedia.org/wiki/Electret_microphone) anyone have an idea which parts would build one?
Have no idea because we have not covered transistors in class.

I was able to locate a document on the web which does a good job explaining how to create a spice model for an electret microphone. I was not able to find an already made model but this should give you some idea:
Hope this helps.
