Hello,
Recently been looking into making a audio to FFT but I'd like to understand the math alot more before moving on. So say if I have a sine wave signal like the one attached, and I take the same amount of samples it did, twice the max frequency (nyquist) how do you figure the different main frequencies in the signal. Not particularly interested in the harmonics, if theres a full example you guys might know of or would like to help me out figuring the one below that would be great.
Thanks
