You may notice similarities to dude837’s Boids sonificiation patch. https://reactivemusic.net/?p=18388 The swarm was replaced by drunken dots.
Audio data for Visualization and Introduction to Open GL
Generally, visualizations will track amplitude, pitch – or any characteristic of audio that is changing over time.

Next week we will look at some of your work in progress for the midterm assignment (that will be due by March 31. Please be ready to demonstrate something or you will have to listen to me again.
Drawing Lissajous curves with Jitter
By Peter Elsea
“Jules Antoine Lissajous (1822-1880) developed a technique for projecting light figures in the 1850s. He placed mirrors on tuning forks and bounced a light beam off them onto a screen. This became a standard technique for studying vibration and enabled major discoveries by Helmholtz and others.”
These two patches are adapted from Elsea’s lecture notes at http://peterelsea.com/Maxtuts_jitter/Lissajous_Art.pdf. The first patch generates curves with two sine waves assigned to X and Y. The second patch adds AM (amplitude modulation). There is an optional feedback module to make visual trails.

Connections

Look at UI’s you have build
rube goldberg machines: Ok go
Using Max to connect external hardware:
Here is a screenshot of the OSC experiment we did in class
Here is a screenshot of the reverse Midi keyboard patch
Reverse engineer Plink. Build a prototype that allows two or more people to jam.
Design a project that will be due at the mid-term. Send me an email next week describing the project.
Write a patch to connect external hardware to Max (input or output)
There will be no class next week, February 10th.

Case study: Adapting and transforming an interactive video performance.

Video and programming by Naoto Fushimi
Here is a case study of how you might approach an interactive video project. For example, if you had an opportunity to design a realtime visualization tool for a band.
Knowing that cool video things can be designed with Max/MSP/Jitter, I opened up Google web search and typed in: jitter max
Here are the results:
The second entry looked interesting: [Share Patch] Simple Audio Reactive Set [Max/MSP Jitter]. (It is the cool video at the top of this post). There is a link to the Max patch in the video description – but the link is broken. So I entered the title of the video into Google: Share Patch Simple Audio Reactive Set
Here are the results:
The second entry is a link to the Cycling 74 forum. https://cycling74.com/forums/topic/looking-for-share-patch-simple-audio-reactive-set-maxmsp-jitter/ Here I was able to find a link to a modified version of Naoto Fushimi’s Max patch – in a post by Giorgio. http://1cyjknyddcx62agyb002-c74projects.s3.amazonaws.com/files/2014/12/NAOTO.maxpat
It appears that audio input is supposed to trigger the interactive graphics. But immediately on starting the audio, it begins to feedback, and there is apparently no way to stop it. I notice there is an ezadc~ object as well as an IO abstraction – but can’t quite see how they are hooked up due to the maze of segmented overlapping patch cords.
By selecting everything (<cmd> a) you can restore normal patch cords by selecting Arrange | remove all segments. After doing this, it appears that the ezadc~ is redundant, so I deleted it. Now the patch looks like this:
Much easier to understand. In the IO abstraction I loaded an audio file and then was able to get graphic output by toggling on the metro at the top of the patch and using the 3 toggles in the center of the patch.
