Hm, happy diwali greetings from India chuckers! So. Lets say I'm shaping a curve, which is the frequency graph of a sound wave, using pygame, or some kind of GUI. So what I possibly have are two things: 1. a string of coordinates that forms the curve. 2. a parametric equation that represents the curve. What is the easiest way in ChucK, by which I can play/generate this sound in case 1) and 2). See? It's getting less stupid everyday :) (eh, Kassen?) regards, dj fadereu ------- -.- 1/f ))) --. ------- ... http://www.algomantra.com
Oh, and i am sending this data to Chuck using OSC, I already got that
working...

Happy Diwali greetings to you to! I had to look it up but celebrating the victory of good over evil by lighting lamps sounded like a very good idea and I just lit a small candle, it's a vanilla scented one, I hope that's appropriate as those are the only ones I have around :¬) Fireworks are illegal here except with new year (Roman callendar) but who needs those when one has ChucK for the explosions?

The easiest by far will be the IFFT Uana http://chuck.cs.princeton.edu/doc/program/uana_full.html#IFFT This takes a array of complex numbers, maps those to frequencies between 0 and the Nyquist and synthesises the result. Basically It's exactly what you are describing you want to do in ready-made form. This does leave questions with regard to the phase of the generated sines. The official examples don't go into this but there is nothing that prevents you from manually filling a "blob" with numbers you like and synthesising that. I have one example of this at hand, I made it a while back to play Kijjaz's "doing lots with little" game. --------------------------------------- IFFT i=>dac;complex c[512];int A; while(1){#(++A%.33,A%1.65)=>c[A%512]; i.transform(c);1024::samp=>now;} ---------------------------------------------------- Warning; not necessarily a pleasant sound for most, watch your speakers, watch your pets. I suggest you do roughly that, except replace my silly formula with a OSC signal.

It never was stupid, don't put yourself down like that. If there were no questions we might was well give up. Questions are good. Yours, Kas.
