EVERY HOMEWORK IS AN OPPORTUNITY FOR GENIUS (says zach)
HOMEWORK 9
Image drives Sound.
Create 4 different audio visual apps which use graphical synthesis as a basis for creating sound. For example, we looked at using raster data to synthesize sound. Think about the relationships between the techniques we've talked about (how graphical and audio synthesis techniques relate), and particularly, how image can drive sound. Make relationships that are tight and meaningful.
I created 2 thus far - this first one is my best attempt at image drives sound... and I probably will use this idea to expand upon for the final.. some sort of bug synthesizer or something - we'll see.
I saw this synthesizer from GATOPODER blog and loved it.. it needed to be shared here!
HOMEWORK 8
In this homework, I want you to have the same basic rules:
a) start with a white square, 200px x 200px, centered on the screen
b) start with a blackbackground
c) draw nothing else on screen
then, based on sonic input, manipulate the square (or the scene). what happens to the square is up to you, does it rotate? does it change in color? grow? bounce? explode? life off the screen? think specifically about sonic qualities, like pitch, and frequency information, and think about performing your white square.
make 3 different examples using the variety of techniques of analysis we talked about, pitch detection, fft, autocorrelation, and volume detection.
BIG THANKS TO GLENDON FOR HIS PATIENT TUTORING!!!
***TURN YOUR VOLUME DOWN - RECORDED TOO LOUDLY***
my very simple square manipulation --- that starts with just pitched being mapped...
this one is pitch being mapped and then color added to the volume...
HOMEWORK 7
Each person in the class will compose 20 seconds of sound (either through some sound software or sampled, recorded sound). they will pass that sound to a neighbor, who will make a drawing / notation of it, in order to communicate the information of the sound. Finally, that second person will pass the drawing on to the next person in the chain, who will make a new 20 second piece of sound...
my equinox sounds here
response drawing from jen cotton
lee's response sounds of jen's drawing
my drawing in response to joe's song
I can't find file of joe's song.. will post it later.
HOMEWORK 6
a) using the volume level (get this by looking for a peak in the buffer) from audio input, make a form of interaction. Think about making something subtle, where the volume is controlling some aspect of the scene. Also, see about using left and right volumes, and also, about the rates of change in volume, etc.
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.
c) record these sounds and include a snapshot of the FFT results ... use the FFT example, and find sounds which have :
a very high frequency (whistling with my mouth)
a very specific frequency (specific meaning constant *not pure* in this context - running water from a fancy facuet)
energy in all frequencies (slurping tea out of my teacup)
very low frequencies (deep humming)
d) use the FFT as input to make a visualizer for audio. think about a meaningful and interesting view of a 'specific' piece of music or sound (not just a visualizer for anything). Can you build something that tells a specific story about the audio, or that reveals some unique qualities ?
This one can be much EXPANDED upon! I enjoyed changing the colors and shapes of your visualizer and adding my own song.. the yodelling trills bounce nicely below... looks more organic. I WILL play with this one more!

HOMEWORK 5
a) make a visual equivalent of granular synthesis (which can be occuring over time, or not). See for example, the work of fred tomaselli (who makes gorgeous paintings out of small pictures that add to a larger whole). think about what kind of textures or visual ideas you can convey with many small pieces.
A few of my photos .. I love the textures in nature and placing many found objects together.
b) hook up the granular synthesis to a different form of interaction, for example, a sequencer or some sort of gestural input. See what parameters make the most sense. Also, experiment with mixing the synthesis techniques we've done before and the granular to make richer tones. Make the most interesting controller / player for the synthesis technique.
This one I also need HELP and ASSISTANCE. I couldn't make it fly yet with my solo skills.. openCV, etc.
I was reading about the performance artist Laurie Anderson .. and she made a granular synthesis instrument.. sounds quite cool! I would have never known what that meant.. prior to this course!
The talking stick is a 6 foot long baton like MIDI controller. It was used in the Moby Dick tour in 1999/2000. She described it in program notes as follows:
The Talking Stick is a new instrument that I designed in collaboration with a team from Interval Research and Bob Bielecki. It is a wireless instrument that can access and replicate any sound. It works on the principle of granular synthesis. This is the technique of breaking sound into tiny segments, called grains, and then playing them back in different ways. The computer rearranges the sound fragments into continuous strings or random clusters that are played back in overlapping sequences to create new textures. The grains are very short, a few hundredths of a second. Granular synthesis can sound smooth or choppy depending on the size of the grain and the rate at which they are played. The grains are like film frames. If you slow them down enough, you begin to hear them separately.
c) Make three of the following tones with the synthesis:
a thick cloud sound - click here to play the cloud sound
a tea pot boiling - click here to play the teapot whistle
**best one** bubbling brook - click here to play the bubbling brook
HOMEWORK 4
a) create an example of waveshaping synthesis. Shape a sin wave via a LUT or function based input. Try altering the shaper over time and thinking about how resolution can effect the output.
I NEED TUTORING ON THIS ONE!!! ..couldn't figure it out myself + I could not get other students code to run and fiddle with... pasted in the src but it kept running errors.
b) create a non - left to right sequencer using any of the synthesis techniques we've talked about or the looping sound player in OF that we discussed in class. Try to make the sequencer both fun to perform and watch.
NON-LINEAR SEQUENCER BEING WORKED ON... posted soon.
HOMEWORK 3
a) using additive synthesis, create the most harmonious, beautiful sound that you can. think about using multiple sin osicllators, with various levels of volume. Be very, very, very careful not to clip your sounds (ie, scale the volumes so that they add up to less then 1.0). Use many oscillators.
code
b) using additive synthesis, create the most evil, terrible, cacophonous and dissonant sound. Again, take care about volume levels.
code
coming....
d) working in groups of two or three, create a sequencer that allow you to compose music by controlling some parameters of synthesis over time. then, create some music with this tool.
code
this is an amazing video of sounds made visible!
HOMEWORK 2
Make a sound story using sounds that you record.
Guidelines:
a) Use no language. think about how sound can be used to give feeling and specificity.
b) 30 secounds or less
c) Try to avoid using any filtering or effects. Editing is possible (cutting, rearranging samples) but try to keep as close to the original recording.
*redo in progress .. the other one was too silly + embarrassing.
HOMEWORK 1
Your job is to create a sound which is less then 5 seconds for each of these images. The sounds can come from anywhere, things you record, things you synthesize, etc.
