Speed and Accuracy

Introduction

Slick user interfaces, insightful data representation and design automation are no use without the solid foundation of an accurate radiation model. Similarly iterative design with a slow model is painful and an optimum solution less likely to be found, either manually or automatically.

Our new software is both quicker and more accurate than anything currently available. The next few pages will describe some of the reasons why.

The 'Directional Point Source' (DPS)
The name despite being an oxymoron has acquired notoriety and is the method employed in every popular sound-field predictor. The operation is quite simple

  1. Obtain a balloon of complex pressure data for your element
  2. Orient these balloons in space to the shape of your array
  3. Define some receiver points
  4. Determine the contribution of each element to each receiver point
  5. Sum all the contributions at each receiver point

Some flavours use higher or lower data resolutions or various methods of compressing the data and different types of interpolation but in reality they all make very similar assumptions about the system of loudspeaker they attempt to model.
