| SoundShell :: weekly :: week#8 |
| Progress-wise, things have gone very well. i know exactly how i want to manipulate the sounds digitally, how to play them back, and how to manipulate them. i changed my PD patch around, and i'm now using stacked bandpass filters and altering the Q level (how much the frequencies outside of the bandpass range are dampened). A high Q level creates very pure, sine-wave-ish tones, like quiet waves echoing in a conch shell. A low Q level creates ominous, echoing noise, which is dampened when the Q level is changed back to high. Manipulating the Q level live creates an interesting balance of sound. Also, because in nature the crystals that form each layer of shell are different sizes, I've added an uncontrollable AI to the patch that shifts individual start and end points of the 8 samples randomly so that they are not always the same size. And, since layer of shell is created at a random offset from the previous layer, this shifting of sample sizes and then live-sampling of the shifts melds the sounds together. Triggering shifts in the start and endpoints also creates a doppler effect, that was initially unintended, but I think I'll use it as a sound source and I will also play live. So, my two physical interactions with the shell would be to trigger doppler shifts using the infra-red sensors on the layers, and to switch between 3 specific Q levels using a footswitch. I've also got a sample (recorded live) at http://stage.itp.nyu.edu/~er557/NIME/soundshell001.mp3 |
