Doppler is very unlikely to be audible. I ran the math for a garden variety 12" guitar driver with the playing the low E at full throttle and playing a high E (12th fret, high E) string at the same time. This basically results in the phase modulation of the high note so the pitch of the high note is modulated at the rate of the low note. The overall ...

One obvious distortion that the overloaded amplifier produces is the saturation: it must already output all voltage is it capable of for a low frequency component and then cannot give any other more for the higher frequency component that should be added to that it is now on the output. Hence the high frequency component is significantly altered (or even ...

In and of itself, the presence of multiple frequencies does not produce any distortion or frequency modulation. The idea of the high frequency waves "riding on" (or being "pushed by") the low frequency waves can be misleading in this context. Intermodulation effects require some non-linearity in the system, i.e. a distortion model. Most the most basic ...
