Abstract

The constantly increasing demand for a better quality in sound and video for multimedia content and virtual reality compels the implementation of more and more sophisticated 3D audio models in authoring and playback tools. A very careful and systematic analysis of the best available development libraries in this area was carried out, considering different Application Programming Interfaces, their features, extensibility, and portability among each other. The results show that it is often difficult to find a tradeoff between flexibility, efficiency, quality and speed. In this paper we propose a low level, modular DSP library, which can be used to implement advanced 3D audio models; it is based on reconfigurable primitive methods required by most 3D algorithms and it provides fast development and good flexibility.
