Record Audio Reactive

Hi, I have made an audio reactive patch, but now I would like to record and save it in JPG or Avi files (anything could be ok).

I try the “writer” nodes but it saves the images to slow I think… and camstudio have some lag.

Do you know a way to have the most responsive reactivity with the best quality as lasal do it for Goniometrie and his other project ?

Thank you.

you should use tonfilm’s FFT recorder
