hi guys
I want to know how to do make the detect and alert system.
My goal:
input signal - condensor mic - noise reduction - amplification - adc - fft - final
I will turn on the sound like siren, if the frequency of sound is more than of scream.
That is my basic idea.
But, I don't have any experience in that field.
I know I have to AVR, mic, and so on..
However, I don't know how to do fft in AVR.
Please any help..
