I am working on a project at the moment and I want to analyse an audio signal and use it to modulate something I am making in jitter. I am a little out of my depth though... I basically want to be able to specify a frequency band to analyse (eg. bass frequencies 50hz to 150hz) and analyse its amplitude into a signal between -1. and 1. and then use that to modulate parameters of the visual patch I am making.
I think I need the fft~ object to analyse, and the capture object....but I don't understand how to turn that into a constant signal...
I had a look at the fft~ tutorial and got quite lost :/ any advice anyone can give is GREATLY appreciated!
