AVZones (AudioVisual Zones) is an iPad app for audiovisual performance, composed of an audio sequencer/looper with a visualizer. By default, 3 audiovisual columns or “zones” allow for the manipulation of 3 audio loops. Each zone had 3 XY pads for audio manipulation: pitch shift, delay and filter. There are 9 sounds available per zone. The application is scalable: the number of zones, XY pads and sounds can be modified in the code. AVZones is open source and work in progress, built with openFrameworks and Maximilian, and part of the Enabling AVUIs research project. Photo by Alessandro Altavilla.
