Hi,
I'm trying to create a simple circuit that controls LEDs through a microphone, NOT through an audio jack. This is similar to those LED rave shirts that respond to sound but I'd like to do it on a smaller scale and without a microcontroller if possible.
I'd like to create something similar to this:

but instead of using an audio jack I'd like to use the electret microphone amplifier here: http://www.adafruit.com/products/1063#Downloads.
Basically have sound coming from the microphone, driving the transistor to control the LEDs powered by a battery. Will this work? Or will I need a microcontroller. Any help is appreciated all the projects I've found use an audio jack and/or require a microcontroller
