Past Event: Sigma Sound Studios - A History in Pictures Film Screening

April 29, 2021 at 7:00 pm

Location: Zoom

Moderated by: Chip Powell

Speaker(s): Arthur Stoppe, Dirk Devlin, Jay Mark, Jim Gallagher and Joe Tarsia of Sigma Sound

Founded in 1968, Sigma Sound Studios was the center of the "Sound of Philadelphia" during the 70s and beyond making Philly a musical powerhouse; eventually expanding into NYC as well.

Sigma Sound engineer Arthur Stoppe, a veteran of 25 years at the studio, recounts its history while presenting an insider's view using photos he took during the heyday of the Philly Sound, including some images not previously shown publicly. The photos show not only the facilities and gear collection (some of it innovative for its time), but provide a behind-the-scenes look at Sigma's staff and clients at work. This is an encore presentation of the video that was shown as part of the “Historical Track” during the fall 2020 AES Convention.

Other Sigma engineers will add their recollections of life in the studio during a panel discussion and Q & A session following the video.

Past Event: How Does It Sound Now?

November 15, 2019 at 7:00 pm

Location: Temple University, Presser Hall (Music Building), Room 142, 2001 N 13th St, Philadelphia, PA 19122

Moderated by: Jules Keenan and Christopher Uzokwe

Speaker(s): Gary Gottlieb, Eastern Region Vice President, Co-Chair, AES Historical Committee and Conference Policy Committee, Audio Engineering Society

When we consider the future of the audio industry, we look to audio students and other young audio professionals. What are the lessons they need to draw from history? Let’s take a look at history ourselves in an attempt to understand the lessons that are available.

One day Chet Atkins was playing guitar when a woman approached him. She said, "That guitar sounds beautiful". Chet immediately quit playing. He asked, "How does it sound now?"

The quality of sound in Chet’s case clearly rested with the player, not the instrument, and the technical and aesthetic quality of our product lies with our engineers and producers, not with the equipment. The dual significance of this question, “How does it sound now”, informed my research from 2007 - 2010 and will inform our discussion, since it addresses both the engineer as the driver and the changes we have seen and heard as our methodology evolved through the decades. The book that resulted from this research, “How Does It Sound Now?” received the 2010 ARSC Award for Excellence in Historical Recorded Sound Research for the Best Research in General History of Recorded Sound.

One of the most interesting facets of the research, comprised of interviews with top engineers and producers, was the way the conversation kept returning to the thread of quality. They loved to talk about how they strived for quality then, and still do.

Let’s talk about how engineers and producers retain quality and create a product that conforms to their own high standards. This may lead to other conversations about musicians, consumers, and the differences and similarities between their standards and our own. It will certainly lead to a discussion of methods to empower young engineers to challenge their clients to strive to create the highest quality product possible.


It will also touch on internships and mentorship, and what young engineers need to know to survive in the changing job market.

Past Event: Sound System Design and Alignment for Live Performance

April 3, 2019 at 6:00 pm

Location: Drexel University, URBN Annex Screening Room, 3501 Market St, Philadelphia, PA 19104

Moderated by: Chip Powell, Chair AES Philadelphia Section

Speaker(s): David Muddiman, Owner Starground Audio; Delaware Authorized Dealer Meyer Sound

David Muddiman has been designing and deploying sound systems based on Meyer Sound components for years. Trained by the master himself, Bob McCarthy, Dave's workflow starts with taking room measurements to input into Meyer's MAPP XT System Design Software to model the loudspeaker to room interface; creating a 3D CAD walk through movie for client presentation; using the Meyer SIM3 Dual FFT Analyzer to guide and verify the on-site deployment; and the Galileo Loudspeaker Management Processor to set and monitor system alignment parameters. We'll demo selected elements of this workflow live and discuss a design Dave will set up later this year for the 50th Annual Woodstock Reunion held on Max Yasgur's Farm in Bethel, NY with Bill Handley, the man who built the original Woodstock Festival system.
