Well I think Audioguru has provided a 'ready to use' mic circuit...so I'll just get all all the reistor and capacitor values and breadboard it as drawn by Audioguru!
Just a little question tho, it about the RC filter for the mic! What is the cutoff frequency? I know how to calculate it but a bit confused with the power supply filter you added...
Coz I want to cut off the 60Hz surrounding noise and have a clean speech signal...
Pardon my ignorance and Thanks again!!
