guitar soundboard resonances?

Hi
I remember someone recently posting a handy link to a chart of vowel formant frequencies; I wonder is there such a quick solution for setting up a similar system in Max for acoustic nylon guitar soundboard resonances; just a quick plug-n-play list of frequencies for [reson~].

And on that subject, how can I convert freq (in reson) to ms (in allpass), so the resonant frequencies coincide?

freq. --> [!/ 4400] seems to work?

Thanks

here's a start anyway:

Max Patch
Copy patch and select New From Clipboard in Max.

hmmm

how should I use my new powers of invisibility?

for good?

or for EVIL, mwah ha ha

LMGTFM :p

I found some general articles (Scott Wilkinson) and some scientific papers (Rossing/Eban), which specify the following:

cavity modes @ 124, 417, 571, 785, 1043 Hz
normal modes @ 101, 184 and 210 Hz, and also
@ 304, 420, 550-660

What I'm failing to find is any reference to modelling these resonances; i.e. at which Q and gain ratios these resonances exist. I could use my highly scientific and methodologically sound method of "messing with parameters until it sounds right", but that could take a while. Any clues?

A spam-bot? Seriously?

You gotta be f**king kidding me
