RE: [Harp-L]Comb test - spectral analysis

[JersiMuse <jersimuse@xxxxxxxxx>]

I've tried this on my harps few months ago.
The results are very interesting, but very much related to the way you
produce the sound on each harmonica you want to test.
You're right Sam, the only varying factor is the way you play each note, but
it is the most difficult to be fully controlled.
One would need to create a material, with a machine which would deliver the
exact same amount of air for each note, with the exact same distance to the
mic, etc.

Spectral analysis can be a good way to get a personal idea on your
harmonicas, but one would need to work seriously on an experience protocol
to make it valuable for a larger test & conclusion.

perhaps this all could be answered very factually by using sonic spectral
analysis. There are tons of cheap/free programs that all work just as well
in showing you the relative levels of harmonics present in a sound. All you
need to do is compare those. The only varying factor is how you play the
harmonica then, but individual bias or 'opinion' has nothing whatsoever to
do with it anymore.
