I would like to post my latest installation "Ichographs" which was done using C++ cinder lib and Pure Data. I used cinder lib to analyze the images, extract and calculate the audio frequencies (based on the colors of the image). These frequencies were sent to Pure Data via OSC. Every color is a sonic frequency. In Pure Data 600 cos oscillators were changing amplitude according to the corresponding color density. The audio part of the video is done 100% in Pure Data.
Note: This video has very low frequencies that are essential. Please use an audio system that can reproduce low-pitched audio frequencies. Built-in laptop speakers and basic desktop speakers are not recommended.

This forum was a great help during the creation of this project and the least I can do is to thank you all!
