| 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 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. |
