FFT Demo
Graphs the harmonic spectrum of various SynthSounds. Uses com.punosmusic.fft.FFTSynthSoundPanel (written in JMSL and JSyn)
Note the difference between band-limited and non-band-limited oscillators.
FM Pair: increase mod index and watch sidebands emerge
Ring Modulation: watch sidebands (no center)
Amp mod (ring mod where one signal is unipolar): see center freq + sidebands
Amp mod (ring mod where both signals are unipolar): see 2 center freqs + sidebands, see big DC
