2016 PNW AES Section Meetings

Return to top of this page. 
December 2016: What's All This Dante Stuff, Anyway? or Audio Networking Using Dante 
The PNW Section held a (rare!) December meeting on Dante audio network technology. PNW Committeeperson Steve Macatee, a former longtime Rane employee and a current SynAudCon instructor, conducted this introduction to Dante.

February 2016: Reference? What Are You Referring To? 
The February meeting of the Pacific Northwest Section of the Audio Engineering Society was hosted by Dr. Michael Matesky at his Bothell, Washington facility, Opus 4 Studios. There were roughly 40 attendees of whom 14 were members of AES. Musicians, audiophiles, and audio engineers often refer to a "reference recording". Exactly what are they referring to, where does it come from, and how is it used? Is there such a thing as a standard reference? How does a reference recording relate to the new recording? This meeting grew out of Dr. Matesky's interest in exploring the way many live and recording engineers and artists use the term "reference recording". Dr. Matesky led us in deconstructing the notion of a reference recording, beginning with a look at the meaning of the term, and extending into a question about the very notion of what an appropriate "reference" might be for the recordist. read more...

October 2015: An Evening of Reverberation, with Sean Costello, René Jaeger and Rick Rodriguez 
We were fortunate to present October's meeting in the gorgeous "Stone Room" at Robert Lang Studio. The story of this studio's genesis is remarkable enough; when you consider the talent that has recorded there, you know you are in a special place.
If you caught our "1000 Years of Reverb" meeting with Sean Costello in June this year, you'll remember that when Sean was discussing classic Lexicon reverbs there was a connection made with a member of our audience, René Jaeger, who was working at Lexicon when the 224 and PCM60 were being developed. When Sean continued with reverbs from the '90s such as the Alesis family of products, Rick Rodriguez, who had worked on the hardware of some of those famous reverberators, joined the discussion. That exchange inspired a riveting panel-like discussion with these three folks, and we wanted to continue the magic. read more...

February 2015: More Topics in Loudness - "Microdynamics" with JJ Johnston 
This is the question James D. (JJ) Johnston presented to the group at the PNW Section February meeting, held at the Digipen Institute of Technology in Redmond, WA. He said it was neither Dynamic Range nor RMS; and loosely defined as "variation in loudness" based on an insufficient number of experiments. After a short review of terms (such as "loudness"), he presented some challenges of using dynamic range as a measure of microdynamics with some examples of number sequences that can "break" a dynamic range calculation. read more...

September 2014 The Perception and Measurement of Headphone Sound Quality: Do Listeners Agree on What Makes a Headphone Sound Good? 
PNW Section started its meeting season with a presentation by Dr. Sean Olive of Harman International and President of the AES. About 57 people (28 AES members) attended his presentation on research into headphone quality, held at Shoreline Community College in Shoreline, WA near Seattle.
Chris Deckard won a special election to fulfill the PNW Section Committee term of Scott Mehrens, who moved to California.
Sean described several studies and papers and 2 years worth of research either presented or to be presented, on headphone sound quality. Headphone sales are now booming, but there is little research or standards on quality and listener preference, not unlike loudspeakers until Sean's recent research at Harman. There are a few measurement standards, but no adherence by manufacturers of consumer headphones, and seemingly driven mostly by marketing. read more...

April 2013 Audio, Radio, and Acoustics, and Signal Processing 
The Richard C. Heyser distinguished lecturer for the 133rd AES Convention is James D. (jj) Johnston. The title of his lecture is, "Audio, Radio, Acoustics, and Signal Processing — the Way Forward." In his talk, JJ will discuss our present understanding of human auditory perception, pointing out how the way we actually work encourages a dichotomy of knowledge that no longer exists. He goes on to suggest some ways that education can bring artistic and technical approaches together, apply some of the technical things we know on the artistic side, and learn what the artistic side of the business needs and wants. He proposes to address such issues as "mix buss performance" claims and the performance of various processors (which are quite nonlinear, for good reason). It is his hope that we can continue to push the understanding of perception, which should help create the "really here" immersive understanding that is the goal of the realists, the "you could never be here but you wish you could" sensation of the avant-garde, and encourage the delivery systems of the world to "get with the program." read more...

March 2013 The State of the Mostly Modular Art of Synthesis 
James Husted of Synthwerks took the PNW AES Section through the history of Synthesis, with particular emphasis on Modular Synthesis. Today's modulars are related to early patchcord synthesizers such as the Moog 900-series, Buchla, and Arp instruments. It took instruments like the MiniMoog or the Arp Odessy to bring synthsesizer sounds to the performance stage, but these instruments, since their capabilities are predefined by the manufacturer, play a minor role in today's modular scene. This meeting was partly a teaser for the MMTA Synthfest, which took place 2 days later at Shoreline CC. read more...

A recording of the tour/presentation and the inside of one of the cooling tower is part of the meeting report. read more... 

  • June 2011: Inside a Cellular Telephone. 
    After we conducted section elections, Scott Mehrens, software engineer with Motorola Mobility, spoke about the modern cell phone, and gave some insight into what makes these things tick. Scott started with a brief history of Motorola, which began in 1928. Motorola made its name with car radios in the early 1930s. By the 1950s, non-cellular car phones were made, and by the 1960s, the space program used Moto radio links hinting at cellular networks that were demonstrated in the late 1970s. 1983 saw the first, huge analog cell phones, and we have seen the evolution to digital and greatly increased capabilities with less size and weight. read more...
