But this is not about sine waves. In my understanding,
the patented method is a way of getting beat
frequencies which are constant along a large range of
main frequencies. I.e. if you have your two
oscillators playing C3, and the beat frequency is 3
Hz, then if you play C4, the beat frequency will be 6
Hz using 'prior art'. Using Apple's method, this beat
frequency will *always" be 3 Hz.
True. But there are still decades of prior art on this one. People
have been doing this with modular synths for a long time, and many
non-modular synths allow you to use fixed-beat type modulation
instead of fixed-ratio.
Unless this patent application was filed a long time ago, or has lots
of other claims in it besides this apparently simple concept, it
sounds hinky to me.
