Description:  Come design your own flavor of audio effect at Stanford University╩╝s Stompbox Design workshop. We will teach you a new platform for implementing audio effects in hardware that not only enables you to re-create sound effects from the past but also promotes the creation of new sound effects. Our resources for new media design are also at your fingertips if you would like to re-design the concept of a guitar stompbox: for example, put a Wiimote on your guitar and use it to change the sound of the effect, or use some LEDs to simulate the glow of vacuum tubes or fire, or even incorporate a micro-sized Pico projector into your project! The expanded world of digital audio effects is at your fingertips because the workshop incorporates:
  • Most basic theory of signal processing
  • Overview of Digital Audio Effects and operation of stompboxes
  • Laboratory exercise teaching you how to program your stompbox kit from computer by means of basic building blocks in PureData, Faust, or C++
  • Design of human-computer interfaces for projects
  • Overview of open-source hardware and software platforms
  • Invited guest lecture by Jonathan S. Abel
  • Further discussion of open-source hardware and software platforms including Satellite CCRMA, Raspberry Pi, Arduino and Pure Data
Finally, we will round out the workshop with a roundtable presentation of your projects followed by an optional evening jam session for fun.

This workshop is intended for:
Musicians interested in exploring new possibilities in digital audio effects in a hands-on and technical way; Makers, engineers, computer scientists, or product designers interested in exploring artistic outlets for their talents and collaborating with musicians; and/or anyone looking to gain valuable skills in basic audio signal processing and human-computer interfaces, with a focus on invention.
Participants are encouraged (but by no means required) to bring their own laptop computers (with Ethernet support) and/or musical instruments. Each participant should bring a pair of headphones, preferably although not necessarily with 1/4" (5.08mm) audio connector.

*NOTE: Participants have the option of purchasing a $169
lab kit at the end of the workshop. The kit contains Satellite CCRMA featuring Arduino and the Raspberry Pi as well as knobs, buttons, footswitches, some other sensors, and an acrylic enclosure. Interested participants can customize the template for the enclosure and laser-cut their own enclosure using a mail-order service.
