April 2018: When Timing Audio For Video Becomes Impossible, aka The Impossible Will Take A Little Longer  In April, the PNW section was hosted by Dr Michael Matesky at Opus 4 Studios for a fascinating look at a real world recording project. 22 attendees including 14 AES members gathered at Opus 4 for the meeting. Once a year, Costco holds a Manager's Conference in Seattle, WA. A segment of the conference program is a memorial to Costco employees who have passed away during the previous year. The memorial takes the form of video images of those who have passed, along with an audio track that underscores the video. The main stipulation from the client is that all the music must be performed by Costco employees. Dr. Michael Matesky and Grant Crawford of Costco walked us through the details with the chance to hear bits and pieces of the project along the way, including the intricate process of combining non-professional performers with a minimum number of takes, many of them working remotely.

2016 PNW AES Section Meetings

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. Read more...	Steve Macatee demonstrates the ease of using DANTE to connect multiple computers and devices on the fly.
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. Read more...	Section Chair Dan Mortensen introduces our distinguished panel of drum experts as they prepare to show us how it's done.

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...

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...

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...	View from the control room as Dr. Michael Matesky, owner of Opus 4 Studios, reflects on the meaning of the term "Reference".
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...
