That's the point I was making. By (x,y)->x I mean that you'd just use the
x (cosine table) for example. The easiest projection is to throw away axes
:)
If you're making shapes as repeated paths in 2-D, then taking a projection
(along an axis x y or any rotation of x,y) will generate a signal t
In the case of the circle I could just use one of the tables, since one has
the cosine and the other the sine, and output that as an oscillator, but if
I want to combine functions to create shapes, e.g. one function for the x
axis and another for y, how can I combine these two dimensions in one?
I
You don't want fft~/ rifft~ for that. It's a mapping between large
structures on blocks and single-samples (and vice-versa).
To get a single sinusoid from a path-defined circle, you just project onto
a single dimension. For example, (x,y)->x or (x,y)->y or (x,y)->
(sqrt(3)/2*x+1/2*y). In the
Yeah, well I'm trying to create shapes in Gem (say a circle) and create the
sound they make. So, to make a circle, I'm making a ramp from 0 to 1,
multiply it by 2pi and send it to [cos] and [sin] and store these values in
two tables, which I then read for every instance of a [circle] (using
[repeat
What you seem to be doing is creating a spectrum which has magnitude 1
everywhere, and the phase is varying at a constant rate vs frequency. That
means it has a constant group delay.
So... my guess is that you'd get an impulse in each block, whose timing
depends on the rate of the phasor. When y
Say I have a full sine and a full cosine cycle stored in two tables. I'm
trying the following to get a sinusoid from [rifft~] but it doesn't work.
