In the violin tuning, a human just
listens to the beats. In principle,
a tone deaf person could do that.
So, the beats just need sensitivity to
volume, amplitude modulation,
not really frequency. So, the
frequency stuff is in the violin, not
the human.
- yzzxy 12y agoComputation is not defined by difficulty for a human. It is closer to being defined by the ability to follow a (possibly arbitrary) decision procedure. In this violin method, a human is required to follow a decision procedure, unlike in a prism or the "Harmonic Analyzer" above.
- graycat 12y agoFine, but the Fourier part is really in the violin and not in the human. Listening for beats is very old stuff in signals, and no doubt circuits and/or software are sometimes used to detect them; if so, then we can do the stuff with the beats without humans.
