Automatic didgeridoo design.

Spasticteapot · 9th February 2006, 05:44 AM

First, I can imagine that you're all thinking the same thing: Wha?

After watching someone play a bit of PVC pipe as a didgeridoo, I was wondering what might be involved in obtaining similar effects, either via "analog" solutions (like a pump, valve, and rubber flappy bits) or digitally (via a speaker or the like).
I'd like to try making a didgeridoo set with at least two octaves, and hopefully some sort of controls that one can manage with a maximum of two hands.

It could certainly be synthesised fairly accurately.
Start with a waveform generator (I'd guess vageuly triangular), followed by a variable comb filter and reverb, and see how it sounds.
As for making a 'mechanical instrument', it sounds fun - have a go! I think simulation of the buccal cavity ('mouth / throat') will be the hardest part.

'Absynth' - a synth by Native Instruments synthesizes a pretty realistic didgeridoo sound.. using almost exactly the above method

id like to see what you came up with though!
