That is just very unlikely, all tones you press on your keyboard
must start with that exact delay that they reach their maxima at the
same time. So the higher tone must start later than the lower one
because it reaches its max quicker when both start from zero. But
yes, if you look at the waveform of some classical music you see a
lot of headroom for the few peaks. Just not a factor 10. Different
story for current popular music. Or music to be listened to while
driving.<br>
