The key to a good loudspeaker system design is the balance between coverage, SPL, and frequency response performances. It deals with various challenges such as directivity control, auditory health preservation, and sonic homogeneity. In solutions that are based on a variable curvature line source, the parameters linked to its physical deployment are often overlooked. The temptation to rely on electronic processing to fix resulting problems can arise. However, it always compromises other performances to some extent, whether system headroom or wavefront integrity. Using Fresnel analysis, this webinar takes a look at important aspects of line source behavior and identifies the effect of determinant parameters such as inter-element angles. It shows how an optimized physical deployment allows for rational electronic adjustments, which then become the icing on the cake.

Want to learn more about the benefits of AVB/Milan networked system architecture? L-Acoustics Director of Scientific Outreach Etienne Corteel and Application Design Engineer Germain Simon will be presenting the AVB/Milan format in this webinar.

L-ISA technology enables the sound of a performer to be perceived as coming from their location on stage and creates natural separation of the multiple sounds. This is accomplished by a combination of loudspeaker system design recommendations and a custom, amplitude-based panning algorithm. In this webinar, we show how the L-ISA algorithm outperforms delay-based algorithms for all types of shows, from soft natural voice lifting, to high SPL performances.

While it is normal practice to fly a main system to improve energy distribution in the audience, subwoofers often remain ground-stacked because of functional limitations and alleged loss of efficiency in flown configurations. In this webinar, our team will demonstrate that the modern subwoofers alleviate some of the practical constraints. Flown subwoofer configurations improve the energy distribution over the audience and can be even more efficient than ground-stacked configurations with equal coverage. The webinars expands on our 2018 article at the 145th convention of the Audio Engineering Society available at https://www.aes.org/e-lib/browse.cfm?elib=19777

Loudspeaker system tuning requires the acquisition of a limited number of measurements that should be representative of the response of the system over the entire audience. The positions at which the responses are captured are crucial to the task. Measurements also provide a snapshot in time that can be disturbed by noise (at low frequencies) or changing atmospheric conditions (at high frequencies). In this webinar, we provide rational recommendations to optimize measurements for EQ and time alignment that have been derived from the analysis of a large set of measurements and simulations.
