The first of its kind, the EAWmosaic™ mobile app offers a comprehensive portable solution to optimize live audio setup of RADIUS speakers. The app streamlines the setup process by using intuitive 3D room design and sound prediction techniques accessible from anywhere in your venue. The easy-to-use controls allow for sound adjustments before and during the event. As one of the first 3D venue prediction pieces of software available on a mobile app, our main challenge was to design a simple tool that transforms complex modeling data into an intuitive, mobile user experience. Our objectives were clear: (a) Simplify and reduce the number of controls that maximize flexibility and power (b) Provide a self-explanatory flow—from square one to completion—with the flexibility for adjustments (c) Create a modern and informative design with no distractions Not only is EAWmosaic™ the best way to optimize the live audio setup of RADIUS speakers, it’s intuitive and simple to learn. A simple PDF can be exported from the app with all the setup information to help guide production crews in the physical setup process. The easy-to-use controls within the app allow for constant oversight, so users can make adjustments before and during the events. Additionally, EAWmosaic™ can be paired and used simultaneously with a Mackie Axis mixer and master fader app.
