In his chapter, Frank introduces an absolute novelty to the didgeridoo scene! He has succeeded in developing software with which the sound spectra of complex didgeridoo interior forms can be simulated. He shows the way to his method and presents some selected results. Precisely and professionally, he describes the physical principles which are responsible for the typical sound of different didgeridoo interior forms. An absolute gem also for seasoned building pros!

Frank has developed probably the most advanced didgeridoo planning method out there - one can look forward to the discussions in the scene that will surely follow this publication.
