Abstract

The usage of advanced audio processing algorithms in products has always
been limited by the available processing power. For powerful concepts
like the wave field synthesis (WFS) the achieved performance is limited
by the execution speed. In the past it was possible to increase the
performance of digital signal processors by increasing the clock rate.
The next generation will be highly parallel heterogeneous
multi-processor systems.
This paper presents a new parallel processor architecture and the first
steps towards an adequate optimization of WFS. A software development
environment which assists in creating scalable programs for highly
parallel hardware will be further explained. An enhanced WFS convolution
structure is presented which use position dependent filtering and
improve the interpolation necessary for moving sound sources.
