First harmonic f1 = 2*f0
Second harmonic f2 = 3*f0
Third harmonic f3 = 4*f0
Seventh harmonic f7 = 7*f0
B) Time reversed
Are A and B of different timbres?
Sound A: Square wave, fundamental 500Hz, 9 harmonics.
Sound B: Square wave, fundamental 500Hz, 9 harmonics,
every second harmonic phase shifted by 90 degrees.
