Aurora update

[Paul Maddox]

Michael,

Thank you, it's sort of one wave which is transposed, except for when you
reach higher notes. When you reach higher notes (>3Khz) the resolution of
the wave will drop to avoid frequency mirroring (what people know as
aliasing, which is in fact two different things).
