Listen, I've wanted a theremin for... well, always. Old Leon is a hero o' mine.
Now I won't rest until I have one.
OMGZ. THIS IS. A WORK. OF TRUE. AWESOME.
"Heres how it works:
The sound from the theremin is split into its frequency and amplitude components in real time, which are then mapped to values in a linear scale representing the X and Y axis. Pitch becomes horizontal control, and Volume becomes vertical control.
The X and Y scales are then cut up into different zones. In this case, Left; Right and dead zones for the horizontal, and a single trigger and dead zone for the vertical.
The trigger zones are then mapped onto a virtual joystick hooked into an emulator.
The end result is a fairly usable input control for playing games like mario. The bars give the much needed visual feedback as to how "in tune" you are, so you have a better feel of where the trigger points are."
Woah. That just blew my mind.
