P9-1 A Hybrid Approach to Live Spatial Sound Mixing—Etienne Corteel, Sonic Emotion Labs - Paris, France; Raphael Foulon, Sonic Emotion Labs - Paris, France; Frédéric Changenet, Radio France - Paris, France
In this paper, we present an approach for live sound mixing that combines object oriented mixing with Wave Field Synthesis rendering with more standard live mixing techniques. This approach combines a standard mixing desk and an external processing unit. We first describe the system and the controls available to the sound engineer. Such system enables to create extensive contrast in the mix working on spatial positioning (angle, depth) but also projection of sound. We then review the use of the system in various musical genre (classical, jazz, pop) describing concrete application installations.

P9-2 Mono-to-Stereo Upmixing—Christian Uhle, Fraunhofer Institute for Integrated Circuits IIS - Erlangen, Germany; Patrick Gampp, Fraunhofer Institute for Integrated Circuits IIS - Erlangen, Germany
A method for upmixing of single-channel audio signals for stereophonic sound reproduction in real-time is presented. To this end, the input signal is decomposed into a foreground signal and a background signal. The background signal is decorrelated using a network of nested allpass filters. The intensity of the decorrelation is controlled using a computational model for the perceived intensity of decorrelation. The foreground sound sources like singers and soloists are reproduced in the center of the stereo image. The proposed method enables upmixing from mono to stereo signals (and can also be applied to enhance the stereo image) with low latency, moderate computational load, and low memory requirements. It produces output signals with a high sound quality and is suitable for automotive and low-bitrate streaming applications.
