  Yes, now I remember a similar discussion with Abe-san^^; The level
values after the FFT is only meaningful in a very controlled
environment.  A clear input from a music instrument with very clear
harmonics and you can see it (according to Abe-san).  But I'd agree
that it is more or less very specific to a certain application.

  The raw level value, that is like the sound recorder's level meter
(which you also had an Etoys that takes advantage of), should be a
tile and it would be more useful.

  Or in a normal case, it is not even necessary.
