The second AES APEI Automotive Audio Webinar, Computational Platforms for Automotive Audio, will explore audio processing requirements and performance workloads in automotive audio, Tuesday, February 23, at 12:00pm EST.
— AES APEI initiative welcomes top industry experts on February 23, 2021 to discuss audio processing requirements and performance workloads in automotive audio —
The Audio Product Education Institute (APEI), an initiative of the Audio Engineering Society, will host the second in a series of webinars on Automotive Audio on Tuesday, February 23 (12:00pm EST): Computational Platforms for Automotive Audio. As auto manufacturers continue to push the limits of existing processing platforms to meet the increasing complexities of automotive systems, this online session will discuss the features that are common to all kinds of processing, and the ones that are unique to audio, identifying the distinctive characteristics for automotive audio applications.
Providing software and hardware perspectives, the webinar will explore the need for deterministic processing and how to manage that key requirement against standard computer hardware techniques, such as caching and virtual memory.
While car manufacturers are building features like fully autonomous driving, they are simultaneously innovating on the in-cabin experience, a huge component of which is audio and voice. Immersive sound and personal audio zones, automotive active and road noise cancellation (ANC/RNC), voice-based user-interfaces and in-car communications, engine sound synthesis (ESS) and electric vehicle warning sound systems (EVWSS/AVAS) are just some of the current areas of focus for automotive audio developers.
Digital signal processing (DSP) core technologies need to deliver on deterministic goals with very low processing latency and best-in-class MIPS/mW performance. Some processors feature hardware accelerators to offload common digital signal processing algorithms from the core, making them the ideal choice for real-time audio applications. Considerations with complex peripherals such as Ethernet and USB bring another level of demands.
This event will be presented by Roger Shively (JJR Acoustics, LLC), APEI's Automotive Pillar Chair, bringing 34 years of experience in engineering research and development, which includes significant experience in product realization and in launching new products at OEM manufacturers around the world. Following opening remarks, the event will feature presentations from Paul Beckmann (CTO, DSP Concepts) and John Redford (DSP Architect, Analog Devices), offering a valuable perspective on automotive audio computational platforms.
In the first presentation, Paul Beckmann will discuss “Mapping Automotive Audio Workloads to the Appropriate Processors,” where he will provide an understanding of the primary automotive audio workloads and detail the strengths and weaknesses of different processors to meet the demands of those applications, with predictions for the next five to 10 years.
The second session, by John Redford, will explore “Distinctive Features of Audio Processing” and the needs to steadily increase performance and reduce the cost of related hardware and software components. The presentation will detail how to deal with audio memory and programming needs in a deterministic environment.
This AES Audio Product Education Institute Automotive Audio webinar is part of an ongoing event series that underscores the AES’s commitment to providing its membership and the industry at large with practical knowledge in designing and implementing real-world applications and innovative sound systems.

The Audio Engineering Society helps the audio industry "Listen, Learn and Connect" with peers and pros in the global audio community
— The Audio Engineering Society looks back on unprecedented events of 2020, while forging ahead in both new and traditional directions for 2021 —
The Audio Engineering Society brings the audio industry together to “Listen, Learn and Connect” with peers and pros around the world – a vital role through the past year’s industry changes, challenges and opportunities. Under the leadership of outgoing AES president Agnieszka Roginska and the AES’s Board of Directors and Board of Governors, with the assistance of the AES staff spearheaded by Executive Director Colleen Harper, scores of volunteers led and served on the committees and working groups that recreated AES services in the face of a global pandemic. Throughout 2020, the AES facilitated paths for advancement in the art and science of audio for audio professionals, students and enthusiasts, while looking ahead towards adding new, additional ways to provide the benefits of Audio Engineering Society membership in 2021. From numerous AES Section events to the AES Virtual Vienna and virtual AES Show Fall 2020 conventions, the addition of abundant new online resources and more, the Audio Engineering Society remains the definitive resource, year-round, for those looking to advance their audio knowledge and connection to the industry.
“AES faced many unprecedented and daunting challenges this past year,” Past-President Roginska reflected. “When I look back on what we accomplished in the face of chaos, fear, and uncertainty, I feel an immense sense of pride – none of these things would have been possible without the commitment of the amazing AES community.”
The AES began 2020 with the sold-out AES Academy in January, a featured four-day event held in conjunction with The NAMM Show 2020 in Anaheim, CA, which was followed in March by the AES Worship Sound Academy held in partnership with Belmont University in Nashville, TN – a first-of-its-kind AES event dedicated to training house-of-worship technical ministry staff and volunteers. These events bookended a victorious advancement for the Society’s AES67 standard with the announcement that the AES would be receiving a Technical & Engineering Emmy® Award for “Development of Synchronized multi-channel uncompressed audio transport over IP Networks.”
As the AES looked ahead to the first AES convention of the year, the Society agilely pivoted and adapted the planned AES Europe Convention into “AES Virtual Vienna,” presenting the AES’s first online-only convention.

Today we celebrate one of the most inspiring figures in our history. As a young person I remember hearing the voice and the messages of Dr. Martin Luther King Jr. He was an essential and inspiring voice during a time in the US when we were holding our cultural attitudes and norms up to the light to see if they measured up to the values that we told ourselves we were living by. We discovered of course that they did not, that there was a lot of work to be done to achieve the goals of equality and equal opportunity. During the time of Dr. King’s prominence, I attended PS 192, a public school in West Harlem that was predominantly African American. It felt as if he was speaking to our community directly. Dr. King distilled a vision and an ideal that left a profound imprint on me and all those around me. It offered us a vision that still resonates and motivates us in our personal lives, as citizens and in our professional life. He offered a vision accompanied by the understanding that we had so much work to do, but it was a north star. A guiding light for our lives.
In recent times we have been repeatedly reminded once again just how much work there is to do. How we must keep re-committing to the work that would bring us closer to his vision. In a speech in 1963, Dr. King gave insights that remain applicable: “Injustice anywhere is a threat to justice everywhere. We are caught in an inescapable network of mutuality, tied in a single garment of destiny. Whatever affected one directly, affects all indirectly.” Here is Dr. King’s address at the Lincoln Memorial (https://www.youtube.com/watch/I47Y6VHc3Ms), where he said, “I say to you today my friends that even though we face the difficulties of today and tomorrow, I still have a dream.”
In spite of the challenges that we face together, and the incredible pain that is experienced by communities and groups of people who historically suffer the consequences of bias, oppression and violence, I am glad to be reminded of the vision. I am glad to be called to recommit to the work we have in common to inch closer to Dr. King’s vision.
The AES is committed to the work. It may take place in places obscured from view. Change may occur in tiny increments that we wish were leaps and bounds, but we are committed. We are committed by the mission statement of the AES to serve ALL our members and all those who are passionate about audio.
I look forward to continuing to work towards an AES that is ever more inclusive and welcome the support and participation of all.

We welcome the change that will result in the renaming of the Gears***z audio forum/platform. We applaud those who shone a light on a name that created friction and unintentionally broadcast a painful message of dis-inclusion to those who are hungry to have a community based on shared interest in audio and who want to learn by participating in that community.
The Audio Engineering Society encourages collegiality and collaboration through membership, and hosts events and forums in the spirit of disseminating knowledge in a supportive, welcoming, and friendly environment. While the forum is not affiliated with the AES, we are encouraged that its leadership listened to those who sought to shine a spotlight on a problem and ultimately by responding with change for the betterment of all.
We support all in the industry who are working towards an environment of inclusivity and who are willing to examine the status quo and implement constructive change.

APEI Automotive Audio Webinar - Direct Validation of Computational Acoustic Results for Automotive Cabin Simulations, Tuesday, January 19, at 12:00pm EST.
— AES APEI initiative hosts online sessions on Automotive Audio, exploring practical approaches in designing and implementing automotive sound systems —
New York, NY, January 13, 2021 — The Audio Product Education Institute (APEI), an initiative of the Audio Engineering Society, will host the first of a series of webinars on Automotive Audio on Tuesday, January 19 (12:00pm EST). Titled “Direct Validation of Computational Acoustic Results for Automotive Cabin Simulations,” the webinar will explore automotive sound system implementation and design in a program presented by APEI's Automotive Pillar Chair Roger Shively (Co-founder and Principal, JJR Acoustics, Seattle, WA). Featured presentations will explore simulation, visualization, tuning and auralization of a car cabin by industry experts Mads Herring Jensen (technical product manager for the Acoustics Module of COMSOL) and Christof Faller (founder and managing director, Illusonic).
Jensen’s session, “Modeling Strategies and Techniques in Car Cabin Acoustics” will cover the important role that simulation and virtual models play in the integration of sound systems into the car cabin environment as well as their calibration. Various modeling approaches and techniques used when assessing these systems will be discussed. Jensen will explain how the low to mid frequency behavior of car cabins is captured with a full wave models, while the high frequency behavior is typically captured with ray acoustics techniques, along with the emergence of new numerical methods and improved hardware shifts the frequency at which ray techniques are applied. The presentation also discusses boundary conditions as well as source characterization.
Faller’s presentation, “Visualizing, Tuning, and Auralizing Car Cabin Simulation Results,” will discuss a useful method for visualizing the results from an FEA or Ray Tracing models, where impulse response information is taken directly from a simulation model or generated from amplitude and phase measurement and imported into an Illusonic tool for reviewing time and frequency data for each point in the measurement data file. In automotive applications, the number of data points could correspond with microphones set in an array for each listening position. The resulting data can be grouped for review and comparison to measured data for the purpose of model updates. The data can also be grouped and averaged for a virtual equalization as well as auralization. This process will be reviewed and demonstrated.
Opening remarks and a question-and-answer period following the two sessions will be led by Shively, guided by the perspective of his 34 years of experience in engineering research and development, which includes significant experience in product realization and in launching new products at OEM manufacturers around the world.
