Here's the latest from my ongoing quest to discover and implement new sound synthesis techniques. The video explains and demonstrates the generation of sound waveforms from the motion of the vertices of rotating 3D-modelled objects. I've called the app 'Rotatosound' (originally thought of 'Rotosound' but that's already the name of a guitar string manufacturer) which implements this 'POVROS' (POlygon Vertex ROtation) sound synthesis method.

Wow - POVROS is certainly different ! 8-)

Have been experimenting with beating sine waves. The results have been promising enough to create a sound engine from (which I'm doing for my next synth).

Here's an example

This phenomenon is a paradox, because the generated frequency spectrum in each case is static - there are no external modifiers like ADSRs or LFOs operating to change which sine waves appear in the spectrum over time (and/or their relative amplitudes).

It is just a certain number of sine waves, all of equal amplitude, generated with a certain spacing and that's it. YET instead of a constant tone, one hears a complex evolving soundscape due to the sine waves beating against each other.

Another example of a synthesis technique about which there is very little in the literature, so had to do something about that :D

Ooh - I LURVE these evolving sounds 8-)

Well done that clever man! :clap:
