Don't care too much about FFT. I've posted those files because it's useful to better understand how a certain waveform is in certain points of the circuit, and what's the harmonic content of that waveform. So you can see if a particular stage adds mainly odd order harmonics (that is not bad as many people think), even order harmonics, but also if it adds low order harmonics or high order harmonics.Marioverkill wrote:I kinda tought its content was related to harmonics.I couldn't decipher it because I had no idea about the Fourier Transform concept.I will study some more.
EG: I like a bit more 3rd harmonic in my vintage-tasty hi-gain lead channels, while in modern ultra-gain I prefer a bit less of it. Spice simulations are pretty good in low order harmonics' analysis.
