Meeting Recaps

Meeting notice archive

Meeting notices   from past meetings. If it's not there, it likely doesn't exist. If you have a meeting topic that you'd like to see covered, please let someone from the Section Committee know about it.

Note that the Meeting Recaps follow the calendar year (the year that the meeting actually occurred in).

n.b. Meeting reports and recordings exist for many past meetings. Audio recording of meetings is a relatively new thing, so those don't exist beyond maybe year 2000 or so. The archive is spotty, but if there is a meeting that you'd like more info on, and there isn't a distinct page on it, do inquire and it just might appear.


  • January 2013 Vroom - The Interesting World of Racing Game Sound Design 
    Turn 10 Studios' (MSFT) Nick Wiswell took us through the process of sound design for an auto racing game running on the X-Box. He talked about the kinds of sounds used, as well as the process of acquiring them, and then the ways that you might employ them in the soundscape of the finished game. For now, there is an audio recording of the meeting, and eventually there will be a link to the MS Research site where you can see a video of the meeting.

    James Husted of Synthwerks took the section through the history of electronic music, culminating with a demonstration of his modular synthesizer rig. This was a teaser for the MMTA Synthfest, which took place 2 days later at Shoreline CC.

  • 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."

    You can read more about the Richard C. Heyser Memorial Lecture Series on the Technical Council  website.

  • June 2013 Everything* You Need To Know About Using Ethernet Cable for Portable Audio 
    What do all those CATegory cable numbers mean? How are they different from one another? Does it matter if you use this one instead of that one? How well do they hold up to repeated deployment? Can you do anything to them while in use that will cause a disruption in your signal transfer? If so, how can you avoid doing that thing? Is it hard to put those little connectors on them? How well do those little connectors stand up to normal use/abuse? How is an Ethernet cable's performance measured, qualified, and quantified?

  • November 2013 Weaponized Audio for Enormous Venues — OR Can We Outshout the Crowd?  Our Presenter for November was Ed Simon, or Edward Simon & Co., designer and installer of sound systems. Of late, he did the sound system design for the newly remodeled Husky Stadium, which speaks for itself. He posed the following points to ponder prior to the meeting:
    • The atmosphere vs. the announcer.
    • The architect vs. the acoustician.
    • Seahawks Stadium: What kind of loud is good?
    • Drivers: Efficiency vs. Flatness - Are you sure about that?
    • Why loudspeaker frequency response should not be flat
    • Can a sound system really add to home field advantage?
    • How loud is enough?
    • 2.5 Megawatts in action! But WHY?
    Meeting Report, with audio recordings.
