Interesting how change in phase of second harmonic distortion was noticable.
Well to my ears anyway, unless there were some other unintentinal changes
too, or maybe it shows up peculiarities in the mp3 compresion.
In real life, directly from the gadget, it's totally inaudible to me.
The other thing I found interesting is that the "Gaussian noise",
which is actually a repeated (single-cycle pattern) of random values
superimposed over the main sinewave, doesn't sound a bit random.
