Hi all,
I am reading Curtis Roads book "The Computer Music Tutorial" trying to understand fft. I get a little lost at times but I think I basically get it. Now how does this information match with the fft~ or rfft~ object in PD I wonder? The help for fft~ says (for that rfft~ at least) the left and right outputs can be considered as the coefficents of cosine and sine respectively. Does this mean that if frequency and phase of a sinusoid can br represented as A*sin(2*PI*f*t)+B*cos(2*PI*f*t), then the left output of fft~ is B and the right output is A? If so, how do I get frequency and phase? (My calculus book is back in Boulder) If I am going to convolve the two signals - multiply in the frequency domain - what happens to phase?
I know that I could open the convo-bros patch and copy/paste, but I would really rather understand the process and write my own patch from scratch.
Thank you for the help! -thewade PS: also, for bug reporting purposes: sometimes if I have a patch running and I open/edit/save an abstraction within that patch i can no longer close that bastraction as PD claims that there is no .X874598743 object (or some number). And feature requests: i would like to be able to decare default font size and level of dialogs in the .pdrc. For example whe I close a window I always get a dialog "are you sure you want to close this window". I would rather close the window and kick myself later for not saving, then get that dialog all the time. PD-devel from CVS
