February 2017: The Science of Turntablism 
For those that still know and embrace the turntable, the PNW Section February 2017 meeting showed the advanced science and technology behind what's known as turntablism. World-touring turntablist Jamie Simmonds showed the art form, while former Rane employees Steve Macatee and Steve Turnidge provided additional technical details. 11 AES Members and 14 non-members attended the presentation held at Shoreline Community College in Shoreline, WA.

January 2017: I Have to Mix it in Here? or Affordable Acoustic Measurements and How to Apply Them. 
For January 2017 the PNW Section had two of their own talk about and demonstrate how to make poor acoustic mixing spaces better. Since most of us are forced to use mixing rooms never designed as such, this meeting showed simple, low-cost methods to figure out what to do and then treat that. James "JJ" Johnston (retired) and Bob Smith (almost retired) spoke to an audience of 62 (27 AES members) at Shoreline Community College Music room 818. Read more...

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. While many audio networking technologies have come and gone, they tend to evolve at the speed of IT technology. Dante (Digital Audio Network Through Ethernet) from Audinate in Australia is currently a big player and has sparked a lot of interest. Their USA office is near Portland, OR. Dante has shown that it can handle uncompressed deterministic (guaranteed packet delivery/timing) digital audio neatly over ordinary Ethernet networks, and has the software tools for easy deployment and simple end user control and management.

November 2016: Drums, Life, and Everything in Between: Understanding the Drum Kit on a Fundamental Level 
PNW Section's November 2016 meeting was held at Robert Lang Studios in Shoreline, WA, and featured a deep examination of the modern drum kit. Local experts enlisted were Dave Delozier (Assistant Manager/Lead Drum Tech, Studio Instrument Rentals (SIR) Seattle), Don Gunn (recording engineer/drummer), Steve Smith (Seattle Drum School founder, instructor, recording engineer) and Seth Tomlinson (Acoustician, the Greenbusch Group, Seattle). The event was co-produced by the AES PNW and the Robert Lang Academy Student Sections, directed by PNW Chair Dan Mortensen and Committeeperson Marlie Pesek, who is also Director of the Robert Lang Academy.

September 2016: Modern Medical Ultrasound Technology 
The PNW Section inaugurated their 2016-17 meeting season with a presentation on medical ultrasound technology by Dr. Jens Quistgaard of Mirabilis Medical, Inc of Bothell, WA. Jens described what medical ultrasound is, how it is implemented, and compared diagnostic imaging with therapeutic uses including destroying tumors with several thousand watts/cm*2. He pointed out the same physical behavior of ultrasound waves to audible sound we are familiar with. read more...

June 2016: Development of a Low Cost Programmable Microphone Preamp Gain Control IC for Pro Audio Applications 
The PNW Section held its season closing and Annual Business Meeting June 29, 2016, and hosted Gary Hebert, CTO of THAT Corp, who spoke about his company's development of a lower cost digital gain control IC for microphone preamps. About 23 AES members and 8 non-members attended the meeting, held at Shoreline Community College (SCC) in Shoreline, WA. This meeting included the elections for section officers and committee members for the coming year. THAT Corporation has been manufacturing programmable gain control ICs for microphone preamplifiers since 2009. While these have been adopted in a wide variety of professional audio products, they were often too costly to be included into many higher volume and high channel count designs. THAT's CTO Gary Hebert described performance requirements for these ICs in the professional audio environment and the circuit topology changes and performance tradeoffs made during the development of a new low-cost gain control IC. read more...

May 2016: Spatial Audio and its Applications 
Dr. Ivan Tashev, the architect behind the audio technologies of many Microsoft products (and PNW Committee member) spoke on Spatial Audio at the May 2016 meeting of the PNW Section. With the recent release of the MS HoloLens augmented reality device, it was timely to now learn how sounds can be manipulated to appear in 3D space. The meeting took place at Microsoft Research's building on one of MS's major campuses in Redmond, WA. Around 58 attendees (26 or so members) were at the meeting, including AES Executive Director Bob Moses. read more...

April 2016: Radio Frequency Coordination for Live Events 
The PNW Section's April meeting featured John Coulter (often known as JC) of the Seattle Center Sound Department, who spoke about wireless audio radio frequency coordination - managing your frequencies, scanning your RF environment and analyzing it, and coping with the ever increasing complexity of less bandwidth and more competition. The meeting involved members of the Art Institute of Seattle's Audio Club and Student AES Section. 13 AES members and 8 nonmembers attended. JC began by noting the tremendous growth in use of wireless audio in shows at Seattle Center in recent years, resulting in him being designated Wireless Frequency Coordinator for Seattle Center. read more...

March 2016: The Decibel, Revisited 
The PNW Section presented its March meeting on "The decibel revisited", a review and tutorial, for both beginners and those of us who think we understand. Our presenter was Mark Rogers, PE, and current AES PNW Section Committee member. Mark is Director of the AV Department at the Greenbusch Group, a Seattle engineering consulting firm. He is a designer of audio/visual systems, including sound reinforcement, audio reproduction, video projection and displays, videoconferencing and audioconferencing, and related control systems. Typical projects include corporate boardrooms, convention centers, universities and hospitals. He has been designing and installing AV for over 45 years, and also teaches classes and seminars on AV technology. He is a registered Professional Engineer (Washington and Idaho) and earned his BSEE at the University of Idaho. He is a past Vice Chair and Committee member of the PNW AES Section and has presented several topics to the section. read more...

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...

January 2016: Sample Rate Conversion: A Saturday Afternoon Discussion 
The PNW Section kicked off 2016 with a Saturday afternoon session about sampling rate conversion (SRC). AES/IEEE Fellow James D. (JJ) Johnston gave a tutorial on sampling, how sampling creates and controls the whole process, what a SRC does, how it works, and what it should and should not do. Bob Smith, of the AES PNW committee and an acoustic scientist at Physio-Control, then gave a presentation about SRC testing, with results showing aliasing and step response of different filters. Snack breaks were held about every hour. The meeting was held at a new, as-yet-to-be-named audio research company in Redmond, WA. 41 people attended, about 18 being AES members. Full A/V documentation will be available as well as the Powerpoint decks of the entire meeting. read more...
