Is there evidence that the pipe harmonic response can be neglected so the audio signature can be extracted solely from the acoustic cavity modes?
I’m tempted to run an harmonic analysis of the fluid-structure system to figure this out…
- jacquesm 3y agoIf you're prepared to model the church as well (or at least the ranks chamber) then you can probably make that work. The interesting part about a church organ is that the harmonics mix pretty much only in the air, not on a soundboard. that gives some interesting challenges in that you need to know more or less exactly how the pipes themselves are arranged in space and church organ designers used this extensively in placing pipes that sound good harmonically in close proximity.

Untractable with today’s hardware… Modelling detailed individual sound sources and mixing their contributions at a particular point in space would be doable though. My point was more oriented toward the effect of the pipe on the sound, e.g. the big square wooden ones probably bring something different than the metallic circular pipes.
