Hi
so I have a working FFT. I tested it but inputting sin waves into it.
will not i am inputting sound waves from a Mic and it is not looking to do...
example:
I am using to youtube vid
it outputs B7 (Musical note) b′′′′ Four-lined 3951.066 Frequency
and I run my program this is what I am getting 3951.066
I am getting more action around 41951, 42112, 20062, and 24035
then
3951.066
so is there anything I am add to my FFT that would help ?
oh I am sampling at 44100 Hz
and my N = 88200
I also tried this one

and I got a higher magnitude from 424.5 and 435.5
then
from 528
do you think there too much noise coming from the computer speakers ?
