So! We can only post about science eh? I happen to be working on an application to emulate a pipe organ in real time. I found some theory of limited use at wikipedia concerning tube resonance but it's not really that informative.

Can anyone make any suggestions?

Unfortunately I know more about electronic and antenna resonance than audio resonance, especialy pipe organ. I can't be of any help. You might have better success in a more appropriate thread. This one certainly about science but mainly SETI, RADIO ASTRONOMY, LIFE IN UNIVERSE, ETC.

Good luck in your quest for pipe organ resonance theory.

Ascii!

Let the ~ be a wavelet.
let ` be half a wavelet.

One end of a tube is fixed, so you will have the waves having different orders.
`
~`
~~`
~~~`

etc.

I assume you are talking about Sound Synthesis with Physical Models.
Check Tao :

Also here is a collection of related links:

Hope it helps.

I suggest you search the web for "pulsejet"... In essence in the tube of a pulsejet are occuring the same kind of standing waves (arithmetically virtually the same). http://www.aardvark.co.nz/pjet/argusv1.shtml has lots of info about waves running through pipes, al be it then to be used as a pulsed rocketmotor...
This may be bewildering to you, but in some of his online construction manuals I remember a very good explanation of the standing wave phenomenon. In essence from mathematical point of view there is not much difference...

Some of the guys outthere on the web really do have weird hobby's...

By the way a very complete book on sound synthesis can be downloaded from : ftp://byrd.math.uga.edu/pub/html/math-music.html

Greetings from Belgium ;-))
