Abstract
A method and device for placement of sound sources in three-dimensional space via two loudspeakers. This technique uses an efficient implementation which consists of binaural signal processing and loudspeaker crosstalk cancellation, followed by panning into the left and right loudspeakers. For many applications, the binaural signal processing and crosstalk cancellation can be performed offline and stored in a file. Because, in this situation, panning is the only required operation, this technique results in a low-computation, real-time system for positional 3D audio over loudspeakers.
