Remote Sound Tuning in Automobiles

June 9, 2021
9:00 AM Pacific (12:00 PM Eastern)

Overview

Continuing to explore automotive audio design and applications, the Audio Product Education Institute (APEI) is proud to present a new webinar addressing remote sound tuning of the in-vehicle acoustics and sound systems. Among other methods, this approach combines computer modeling, measurement and tuning parameters to compute a simulation of impulse responses, frequency responses and acoustic combinations, with possible virtualization.
 
Tools exist for remotely measuring a car audio system, visualizing the data, auralizing it and tuning it with very close accuracy to the in-vehicle experience. Firmware can be updated remotely, and the tuning process continues as it would normally, except that it is virtual. During a time when travel was restricted and access to vehicles was limited, remote tuning became a valuable, if not essential tool. Subjective evaluations have been performed remotely, using remote tunings of physical cars and virtual models. 
 
Is there a collective will to continue to explore its use as part of the automotive audio design process? Or is the psychological break between tuning live and tuning through headphones too great? In this session, Roger Shively (JJR Acoustics, LLC) APEI’s Automotive Pillar Chair will welcome presentations and a panel discussion with four automotive industry experts, discussing their experiences with demonstrations of the methods used.
 
Roger Shively (JJR Acoustics) and Shelley Uprichard, Tonmeister, independent audio engineer, frequently consulting in perceptual audio and tuning, will co-host the session and present on the subjective evaluation work. Marc Levasseur, independent audio engineer and consultant, with extensive experience in automotive audio sound tuning, will describe his use of Illusonic’s solutions, together with Christof Faller (Illusonic founder), who will demonstrate auralization with head-tracking and headphone compensation equalization. Finally, Michael Fabry, General Manager at DSP Concepts Germany, former founder of S1nn, and manager of audio systems for companies such as Harman/Becker and Bose, will demonstrate capturing the acoustics footprint and offline tuning. The two hour session will conclude with an opportunity for questions from attendees.
Michael Fabry

General Manager, DSP Concepts GmbH
