Past Event: When Timing Audio For Video Becomes Impossible aka The Impossible Will Take A Little Longer

April 25, 2018 at 7:30 pm

Location: Opus 4 Studios, Bothell, WA USA

Moderated by: Dan Mortensen

Speaker(s): Dr. Michael Matesky, Opus 4 Studios & PNW AES Committee
Grant Crawford, Costco

 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 only stipulation was that the music had to be performed by Costco employees. Simple enough, eh?

This year, there were two songs to be used, Song #1, Going Home, a spiritual, and Song #2, Hallelujah, by Leonard Cohen. Both songs would play against a video track that was being created at Costco HQ in Issaquah.

Going Home was to be recorded in English, French, Spanish, and Korean. The vocal would be added as an overdub, in the home country of the language; i.e. here, France, Spain, and Korea. Grant recorded a basic piano track at Opus 4 Studios without knowing the final tempo or key, and that's what was sent around to each country. Everyone got instructions about microphone choice, processing, etc. Each country would sing the entire song through, and the production team here would pick and choose what parts to use where. Simple enough, eh? What could go wrong?

Hallelujah was to be sung by yet another singer, with a small studio band. After some searching, they found their singer here in the PNW, BUT she had NEVER been in a recording studio. The "band" was guitar, bass, synth/keyboard, and backgrond vocals. With the exception of Grant (synth/keys), everyone was an amateur, albeit a Costco employee. What could go wrong?

Finally, as mentioned before, the songs underscore a video, which was being produced elsewhere at Costco, without the video team really hearing the music AND the audio team not seeing the video. A third party was calling the shots to both, to the extent that the production was evolving somewhat independently in two different but mostly parallel universes. The upshot of this was the audio team getting requests from Corporate that at such and such time, something had to happen, and the audio track would have to morph somehow to accommodate the request. This might be as simple as a fader move, but more commonly, it resulted in arrangement changes on the fly. Ohhh, of course the deadline is tighter than a  <<pick something impossibly tight]>> . What could possibly go wrong?

Come to our April meeting and find out how Dr. Mike and Grant made the impossible into a reality. Dr. Mike has still not seen the finished film (or even any of the rough cuts).

Past Event: Roland Cloud and Gig Performer | The Continuing Evolution of the Virtual Studio

February 20, 2018 at 7:30 pm

Location: The Guitar Store, 8300 Aurora Ave N. Seattle, WA 98103 USA

Moderated by: Dan Mortensen

Speaker(s): Brandon Ryan - Roland, Dr. David Jameson - Gig Performer

 Over the course of decades, the audio community has focused their attention on the tape recorder and the evolutionary results have become the modern Digital Audio Workstation (DAW). Increasingly, the common denominator in music making has been Virtual Studio Technology (VST) instruments and signal processing gear (a standard developed by Steinberg). See https://en.wikipedia.org/wiki/Virtual_Studio_Technology for more details.

Now, subscription services are starting to take over - many computer software licenses are maintained by a monthly payment. Roland Corporation, one of the best known brand names in synthesis, recently started a subscription service - Roland Cloud - which provides VST instruments modeled on (down to the resistor!) a large assortment of their classic synthesizers and other forward looking products.

One challenge Roland (and many other VST providers) have, is that in order to use these VST instruments, the subscriber has to have access and working knowledge of a DAW able to mount these instruments and use them before the instant gratification of actually playing and hearing them. The "tape recorder" has taken over the studio.

Enter Gig Performer - A VST host that provides direct and immediate access to these instruments - and any VST processor or utility. When you open Gig Performer, you see your audio and MIDI interfaces on a desktop with connection points. Right click and select the VST you wish to use, connect them up with your interfaces, and you are playing. Near instant performance gratification.

Come see us at The Guitar Store on February 21, 2018 at 7:30 for a full run down of the future of the virtual studio.

Past Event: To Window, or Not To Window...

January 30, 2018 at 7:00 pm

Location: Digipen Institute of Technology, Redmond, Washington USA

Moderated by: Dan Mortensen

Speaker(s): James J. (JJ) Johnston - retired AT&T/Bell Labs, Microsoft, Bob Smith - Stryker/Physio Control

 To Window or Not To Window

aye, there's the rub!

 

Presented By
James J (JJ Johnston) - AES and IEEE Fellow
Bob Smith - AES PNW Section
and
The Pacific Northwest Section of the AES

 

 

Tuesday, January 30th, 2018, 7:30pm
Digipen Institute of Technology, Redmond Washington

 

Our January meeting will deal with the matter of windowing in FFT analysis.

Mr. Johnston will explain why windowing exists in FFT analysis, and then show the properties of a few windows, as well as mention when a window might not be the right tool. The talk will be primarily powerpoint, with rather a lot of graphs showing what happens when you do and don't window, why it's usually a good idea, and when it's actually not such a good idea.

Bob Smith will add clarity by discussing the practical effects of window choices on audio measurements. He will demonstrate these concepts via several live amplifier measurements.

Our Presenters

James D. (JJ) Johnston received the BSEE and MSEE degrees from Carnegie-Mellon University, Pittsburgh, PA in 1975 and 1976 respectively.

Past Event: The Brain-Music Interface: The Encephalophone

October 25, 2017 at 7:30 pm

Location: Digipen Institute of Technology, Redmond, Washington USA

Moderated by: Dan Mortensen

Speaker(s): Thomas A.S. Deuel - MD, PhD

 Can our brains be somehow connected to and directly operate a musical instrument (with the aid of some electronics)? Our October meeting explores that premise with Dr. Thomas Deuel, of DXARTS at the University of Washington. Dr. Deuel will discuss his brain-music interface: The Encephalophone.

The Encephalophone is a hands-free musical instrument. It uses EEG "brain-wave" measurements to allow users to generate music using only thought control, without movement. It is based on using Brain-Computer Interfaces (BCIs) to harness the electrical brain signals to create music in real-time using conscious "thought" control. It has been experimentally shown to work with reasonable accuracy, and is being used in clinical trials with patients with motor disability caused by stroke, MS, ALS, or spinal cord injury to enable and empower these patients to create music in real-time without needing to move.

Dr. Deuel plans to give a talk and screen video examples of the Encephalophone at work, followed by Q&A. Come and enjoy!

Maybe, just-maybe, a few folks will share a few minutes of their experience at this year's AES Convention....

Thomas A.S. Deuel, MD, PhD

Musician/Sound Artist, Neurologist, and Neuroscientist. He has been a University of Washington Acting Assistant Professor at the UW School of Music's DXARTS (Center for Digital Arts and Experimental Media). He is also Staff Physician/Neurophysiologist for Swedish Hospital, Seattle, WA. He has received several awards and grants for his work, and has given several invited talks on the Encephalophone.

Past Event: A Pictorial History of the Columbia Records 30th Street Studio

September 27, 2017 at 7:00 pm

Location: Redmond Washington, USA

Moderated by: Dan Mortensen

Speaker(s): Dan Mortensen - Friends of the 30th Street Studio, Dansound Inc Seattle

 A Pictorial History of the Columbia Records 30th Street Studio

 

Presented By
Dan Mortensen - Dansound Inc/Fo30St
And
The Pacific Northwest Section of the AES

 

 

Wednesday, September 27th, 7:30pm
DigiPen Institute of Technology - Michaelangelo Room

 

Directions to DigiPen

When our friend Frank Laico told us at Section Meetings between 2008 and 2012 about his career in recording, he described a wonderful yet somewhat inscrutable place called the 30th Street Studio. It was located in Manhattan NYC at 207 East 30th Street.

It was described as an abandoned Armenian Church that Columbia turned into a recording studio where marvelous sounding recordings were made for over 30 years, and which was recognized as so perfect-sounding immediately upon acquisition that the decree went out: Don't change anything in it, don't wash the floors or paint the walls or fix it up in any way. Leave it like it is!

It was also described as a gargantuan space (100' x 100' x 100') that had perfect reverberation.

We know that a remarkable number of extraordinary-sounding recordings came out of it that we still listen to today, but the particulars of its structure and spaces were lost to demolition, and as we asked more questions the details got fuzzier.

Dan Mortensen, co-moderator of our meetings with Frank, became more and more interested in those nagging details and has been pursuing research into it ever since his first meeting with Frank in December 2008. Dan has founded a group to memorialize the studio called Friends of the 30th Street Studio (Fo30St), and has held four meetings in New York since 2012 in which people who worked there or are interested in its memory gather to discuss it and to see the fruits of Dan's and other people's research and share memories.

The truth is that Frank was remembering through nearly 50 years of memories without much physical evidence, and as entertaining and plausible as the memories were they were not fully accurate. The spirit was entirely correct but not the complexity of reality.

Come join us and see and hear our current understanding of what the studio was over its 33 year life span and how it came to be. There will be lots of pictures, not a lot of music as this is about the studio and not its product or its people. The studio story is complicated enough.

Past Event: 3D Sound for Video Games

June 21, 2017 at 7:00 pm

Location: Digipen, Redmond, WA USA

Moderated by: Dan Mortensen

Speaker(s): Lawrence Schwedler, Digipen

 Audio for video games has come a long way since the days of programmable sound generators in the early home consoles. Recent development of virtual and augmented reality for the consumer market has brought about rapid innovation in systems for the realtime rendering of three-dimensional, spatial audio that replicates the way sound waves interact with our ears and head, and with the environment.

This talk will include a brief history of game audio, definition and disambiguation of terminology, and an overview of some of the current methods for rendering spatial audio over headphones and loudspeakers. We will also demonstrate Dr. Edgar Choueiri's BACCH system for binaural audio over loudspeakers, as well as a VR game utilizing a commercial 3D audio plugin. 

Other Business: Our Annual Election will take place at this meeting. If you're a member, please attend to help ensure that we have a quorum.

Past Event: The Harry Partch Instrumentarium

May 30, 2017 at 7:30 pm

Location: Meany Studio Theater, University of Washington, Seattle, WA USA

Moderated by: Dan Mortensen

Speaker(s): Charles Corey, Curator, University of Washington

 Harry Partch (1901-1974) was an iconoclastic American composer and instrument inventor with a passion for integrating musicians, actors, and dancers in large-scale works of total-theater. He was "seduced into carpentry" by his interest in just intonation and his need to have an orchestra tuned to this system. The instruments are more than just producers of tone, however — each one has an evocative name and dramatic physical presence, and each one puts unique physical demands on the performer. In Partch's book, Genesis of a Music, he writes that the performer of the Marimba Eroica should at times "convey the vision of Ben Hur in his chariot," while a musician playing his Kithara must not "bend at the waist, like an amateur California prune picker," but instead should move with grace and athleticism in a "functional dance."

During his lifetime, Partch composed numerous works for his instruments. Some pieces are straightforward concert music, while others include components of film, dance, or theater. He made great use of the human voice in his music, requiring instrumentalists and singers alike to 'intone' spoken words on precise pitches. His compositions dealt with subjects ranging from ancient Greek mythology and classic drama to his own life experiences as a hobo in 20th century America.

After Partch's death, his orchestra of over 50 unique instruments was left to his dedicated assistant, Danlee Mitchell. Danlee continued performances of Partch's works from his base at San Diego State University until 1990, when Dean Drummond, a former member of Partch's ensemble, became the curator of the instrumentarium. In 2013, Charles Corey, a member of Drummond's ensemble, was appointed curator, and has worked closely with Danlee Mitchell to continue the legacy of Harry Partch.
