Visualizing Sound with Processing

Although Processing does not have the ability to process audio on it’s own there are a few libraries which can be used to add such features. I’ve been experimenting with the ESS library but you can find others from the processing libraries page. Gathering Data from live or recorded sound can be a powerful tool for artists and designers in creating interactive applications, audio visualizers, music videos, or anything else that could involve an interaction with sound. Getting the data is fairly straight forward and the script returns an array of data updated each frame. This demonstration with display the data very simply, however, the numbers could be applied to any attribute in any system to produce different effects.

Augmented Reality with Processing [Tutorial, Processing]

CAN Augmented Reality Tutorial from Amnon Owed on Vimeo.

All of the visuals in the above video were created using NyArtoolkit for Processing. NyARToolkit is an augmented reality toolkit built with 100% pure Java. It is derived from ARToolkit-2.72.1. Like Processing itself it’s open source and free! In this tutorial you will learn how to use it to place computer generated imagery correctly onto real world footage. To do this in real-time NyArtoolkit uses markers – black and white images – to determine the three-dimensional position and orientation in the real world. Most likely you will have seen something like this before, but now you will learn how to do it yourself using freely available software.

Five great Processing sites

via Make

OpenProcessing. OpenProcessing is a community-driven site where people can share their portfolios. You'll find a vast array of creative sketches that range from art to science. For example, GUIGUITROCHOID by Guigui simulates the gears in a Spirograph. In addition to enjoying the visual beauty, you can also view the source code from any sketch to see how it works.

Learning Processing. This site is home for ITP Professor Daniel Shiffman's book Learning Processing. Although this book doesn't cover Arduino, it covers almost everything you would want to do in Processing, and is a great book to tackle once you've learned the language. The section on video has many creative mirrors, like "Video Pixelation."

The Nature of Code. Another great site from Daniel Shiffman, this site covers "topics ranging from basic mathematics and physics concepts to more advanced simulations of complex systems. Subjects covered will include forces, trigonometry, fractals, cellular automata, self-organization, and genetic algorithms." In addition to all the great Processing code, you'll also learn the physics behind the code. For example, the material on vectors and path following will be helpful to anyone doing robotics.

Ben Fry's Project Page. This site has a number of projects by Ben Fry, Processing's co-creator. Although light on code, the examples show the full range of amazing data visualization possible with the Processing language. (Most of the code for the projects are in his Visualizing Data book). The site also has several interesting examples of visualizing genetic data, but my favorite are the ones of source code from Atari 2600 games.

processing.android. This site compiles videos from a number of workshops on running Processing on Android, the popular mobile phone operating system. In addition to the basic graphics, the site has videos on how to use libraries to read data from a phone's sensors.
