• The modern pipe organ can have as many as 10 000 pipes, each of which is a simple sound generator. In order to digitally synthesize a pipe organ, each pipe requires its own digital waveguide model due to its individual geometry and state. To complicate the matter, pipe geometry can vary greatly across different pipe organ ranks, pipes can be reed-driven or air-jet-driven, and it is possible for a single key to sound many ranks at once. As a result, developing an acoustic model of even a small pipe organ is intensive both in the modeling and in the computational demands for real-time synthesis. For modeling the pipes, we propose a scalable lossy digital waveguide framework whose parameters can be changed based on a pipe's geometric model. We utilize the Faust functional programming language to produce high-performance digital signal processing code.
