Real-time Spatial Mixing Using Binaural Processing

In this work, a professional audio mastering / mixing software platform is presented which employs state- of-the-art binaural technology algorithms for efficient and accurate sound source positioning. The proposed mixing platform supports high-quality audio (typically 96kHz/24bit) for an arbitrary number of sound sources, while room acoustic analysis and simulation models are also incorporated. All binaural calculations and audio signal processing/mixing are performed in real-time, due to the employment of an optimized binaural 3D Audio Engine developed by the authors. Moreover, all user operations are performed through a user-friendly graphical interface allowing the efficient control of a large number of binaural mixing parameters. It is shown that the proposed mixing platform achieves subjectively high spatial impression, rendering it suitable for high-quality professional audio applications.
