Hi,
I am interested in writing some code to analyse sound in realtime through the
line in input on my soundcard. I would like to be able to extract certain
frequencies from the incoming sound and use these values to create visual
effects that respond to the music as it is playing. Does anyone have any ideas
about how to achieve this? Any help would be appreciated such as how to receive
data from the line in and specific algorithms. I have heard that the fast
fourier transform may have something to do with what I am trying to achieve -
can anyone confirm this?
Cheers,
