I'm trying to do a audio spectrum analizer using a 16C73 and the only
problem I have is how to measure the amplitude of the incoming signal.
I have to measure the amplitude at 32Hz, 64Hz, 125Hz, 250Hz, 500Hz,
1000Hz, 2000Hz, 4000Hz, 8000Hz and 16000Hz.
I don't want to do a separate bandpass filter for each frequency, I just
want to dos this by software.
Does any one have any ideas?
