CLICK ON EACH WEEK NAME TO EXPAND POST!!!

a) Dialation Click for Image!
b) Erosion Click for Image!

a) Square Swarm - A maximum of 16 time-recorded gestures can be drawn. Each gesture plays back as a drawn square and a square wave oscillator. The gestures really come to life with the audio, like the "jump" sound in the beginning of the video or the swarm at the end!

b) Gravity Drum - Bouncing balls on a drum skin, with a little gravity to phase rhythms...inspired by Pascual Sisto's video "28 Years in the Implicate Order "

c) Perlin Waveshaper - Using a row of pixels from a sample of Perlin noise to shape a square wave dynamically!

a) Parrot Machine - Toggle recording a phrase with the spacebar, animates a little character!

b) Color Recorder - Toggle recording a phrase with the spacebar, plays back a colorful one dimensional waveform (THE VIDEO ON THIS KIND OF CHOKES, ARGHH)

c) FFT Square - Square comes to life when the average magnitude of 9 bands of FFT are above .9/1 ...

a) Visual Notation of Jen's sound

b) Song for Lee based on Jen's picture.

a) using the volume level (get this by looking for a peak in the buffer) from audio input, make a form of interaction.
b) make a “volume” controlled switch (see for example, claudio’s automatic recording system). Use it to make some interesting work where sound is used as input, but noise is not.
* (FOR A & B!)Created an application that is like a little pinwheel, and only triggers spinning if the average magnitude of all the bands is high enough (a blowing sound accomplishes this!).


c) use the FFT example, and find sounds which have : (I had trouble capturing video and audio at the same time on this one ;_;)
– a very high frequency * GLOCKENSPIEL
– a very specific frequency * SCRATCHING A METAL THINGS TOGETHER
– energy in all frequencies * CAR KEYS
– very low energy in all frequencies * SCISSORS CUTTING
d) use the FFT as input to make a visualizer for audio.

a) Visual equivalent of granular synthesis (which can be occuring over time, or not) CLICK TO SEE.
b) Hook up the granular synthesis to a different form of interaction.
*Used the Nintendo Wii controller and the mouse where Mouse X controls the average frequency value, and the pitch and roll of the Wiimote control the average frequency spread and the average grain length spread, respectively. (DarwiinRemoteOSC is needed to try this example and is included in the zip file).

c) Make three specified sounds with granular synthesis.

a) create an example of waveshaping synthesis, using a lookup table.
b) create a non - left to right sequencer using any synthesis techniques.


*This is a sequencer that uses Conway's game of life to calculate the frequency. A random lookup table is generated for the wave every time the spacebar is pressed.

a) Using additive synthesis, create the most harmonious, beautiful sound that you can.
*Harmonious beat frequencies...thinking of Steve Reich and Alvin Lucier


b) Using additive synthesis, create the most evil, terrible, cacophonous and dissonant sound.
* Sounds way more brutal with a subwoofer...evil subharmonics!


c) Try to see what the limit of your computer is by adding as many sin oscillators as you can together.
*The code is in the zip file, press any key and it dynamically adds an oscillator to a vector of oscillators and recalculates the volume for all of them (to avoid clipping). I can get about 100 oscillators going before it craps out. I couldn't capture the audio or video at the same time because it was making my computer crash ;_;

d) using any synthesis technique, attempt to recreate these tones: Dial tone, Ringing, and Cappuccino Machine


e) Create a sequencer that allow you to compose music by controlling some parameters of synthesis over time.


*This sequencer is a simple step sequencer that uses custom square wave and noise oscillator classes. The overall sound is inspired by Kraftwerk's "Radioactivity"

Make a sound story following these guidelines:
> Use no language.
> 30 seconds or less
> Avoid using any filtering or effects.
