Hi. I think it's wonderful that ChucK can do analysis now. I know what the FFT is but having very little experience with Fourrier transforms I'm quite in the dark on how to modify them. I'm trying to create a realtime pitch-shifter but I'm having trouble getting the phases of successive segments to match. Is there anyone here who knows more about FFT and could write a pitch-shifter example. The short examples that come with Chuck can get people started on how to use the Uana objects but more detailed examples like a phase-vocoder or a pitch-shifter would really help clear some heads on how to truly utilize the power of analysis in ChucK.
