Hey no worries! In the realm of audio descriptors centroid and brightness go far in terms of mapping on to something perceptual. I use them all the time for doing basic corpus navigation and concat synthesis. This indeed was an experiment because I wanted something that respected more perceptual features of the sound. I am in the process of writing my results up into a thesis actually.
