Hey guys,
I'm trying to build a circuit where I can put in an analog signal (my voice) and have it output the same signal with a much lower pitch (speech synthesizer). Is there any way I could do this with primarily a 555 timer?
I'm able to pulse width modulate the analog signal, but I don't really know where I can go from there. I was thinking about bringing in the analog signal via ADCs and then changing the frequency of all of the bits via a few 555 timers and finally DACing the signal into a speaker, but all I get is junk (sampling frequency issue?).
Any ideas?
