AES International Conference on Spatial and Immersive Audio

Trade show
August 23, 2023 - August 25, 2023

L-Acoustics will participate in the AES International Conference on Spatial and Immersive Audio from August 23rd to the 25th. This conference gathers 200 international experts, both from academic and professional worlds, to discuss recent technological and scientific trends and discoveries in the field of immersive audio. We are proud to be a gold sponsor of the conference, providing an L-ISA Loudspeaker System for the conference sound reinforcement and immersive audio demos featuring the latest L-ISA technology development by Chris McDonnell and Jeff Woodford. L-Acoustics also contributes to the scientific program of the conference with Phil Coleman participating to a panel on “The Future Of Spatial Audio Reproduction Over Loudspeakers”, and a scientific paper entitled “On the perception of musical groove in large-scale events with immersive sound”* presented by Etienne Corteel on August 24th at 11:30am. *Description: Immersive audio is increasingly used in large-scale live music events. The dimensions of the audience area impose that propagation times from several loudspeakers to a given audience position can be significantly different. This may be perceived by listeners as a loss of time synchronization between sound sources, which in turn affects the perception of musical groove. In this paper, we first investigate the range of propagation time differences that can occur with large-scale loudspeaker deployments. The results of a listening test confirm that time differences may degrade the rhythmic characteristics. The degradations may depend on the musical content but not on the spatialization. Mixing guidelines and methodologies are finally proposed to overcome the potential issues. The exact schedule will be communicated closer to the event. We look forward to seeing you there!
