Abstract : Audio processing applications are among the most computeintensive and often rely on additional DSP resources for realtime performance. However, programmable audio DSPs are in general only available to product developers. Professional audio boards with multiple DSPs usually support specific effects and products while consumer "game-audio" hardware still only implements fixed-function pipelines which evolve at a rather slow pace. The widespread availability and increasing processing power of GPUs could offer an alternative solution. GPU features, like multiply-accumulate instructions or multiple execution units, are similar to those of most DSPs [3]. Besides, 3D audio rendering applications require a significant number of geometric calculations, which are a perfect fit for the GPU. Our feasibility study investigates the use of GPUs for efficient audio processing.
