Virtual Sound Source Positioning and Mixing in 5.1. Implementation on the Real-Time System Genesis
The aim of this article is to compare two multi-speaker spatialization techniques - Vector Base Panning (VBP) and Ambisonics - on a particular loudspeaker layout. Theory is presented for configurations in the horizontal plane. A way to deal with the elevation effect for such layouts is proposed. A new "local" panning method is introduced. VBP and Ambisonics are compared on a 5.1 configuration by means of objective simulation and preliminary listening tests on the real-time DSP system Genesis. This study could find recording and mixing applications in home cinema and multimedia.
