Audio Visualizer

To incorporate interactive art with audio and visual outputs, I created interactive audio visualizer using Arduino and Processing 3. There are 6 capacitive touch sensors linked to the Arduino, and each one on the end of a yellow key. The keys are displayed in a half-circle format on the presentation table to engage the user and allow them to discover the piece through interaction. By activating a touch sensor on the end of a key, a visual developed on Processing 3 and linked to the specific capacitive touch sensor is displayed. The visuals respond to the amplitude of an open source audio track that plays on a loop in the background of the processing sketch. Each key coordinates to a unique visual output. Multiple keys can be activated at once to combine the visual outputs on the screen, allowing the user to develop a variety of visual responses to the linked audio track.

I chose to develop this project based off of a previous audio visualizer I developed, as I wanted to turn a basic Processing audio sketch into an interactive work. The bright keys, visuals, and energetic audio track were able to engage the users and provide a visual experience to compliment and re-define an audio track. In future iterations of this project, I hope to develop a large number of interactive keys and the ability to switch between audio tracks, as the visuals are projected across multiple walls surrounding the user.
