Smaart V8

Smaart is an FFT-based audio analysis program. The name stands for System Measurement Acoustic Analysis Real-time Tool. Smaart can be used in many ways to examine sound systems in detail in order to diagnose and solve problems, and to confirm proper setup and operation. It can also be used to characterize the performance of and diagnose problems with the components of those sound systems, as well as components of the system's acoustic output itself and the space containing the sound. In many ways, the program's capabilities are only limited by the user's imagination, and this meeting will explore these capabilities and more.

Starting off with a brief history of FFT audio analysis, we'll look at how it got translated into audio use, and how Smaart came to be and to evolve into what it is today. Rational Acoustics' President Jamie Anderson, who has been present and active in much of the history of FFT audio analysis, will share some of that history with us.

Jamie and Michael Lawrence, Rational Acoustics' Application Support Specialist and Smaart SPL Product Manager, will guide us through some of the ways Smaart is used to assist in evaluating sound, both conventional and unconventional. This includes the idea of "sandbox engineering," which is using your available tools to design experiments that allow you to answer your own questions rather than waiting for someone else to answer them for you.

Our own Bob Smith will be on hand to share his experiences and usages of Smaart. Other attendees' experiences and usage stories will be welcomed.

This Zoom meeting is free to all, and free tickets are available at the Eventbrite link below. We require that all present use their real names in Zoom, mute your microphone and turn off your video during the presentation except when asking questions, and that each attendee gets tickets through Eventbrite (no account needed, no ticket sharing) so we can know how many people are going to attend. Our Zoom account has a finite capacity.

The Presenters

Jamie Anderson has been teaching and working in the field of sound system engineering, measurement and alignment for over 25 years. Prior to founding Rational Acoustics, he worked as a technical support manager and SIM instructor for Meyer Sound Laboratories, as a system engineer on tour for A-1 Audio (kd Lang) and UltraSound (Dave Matthews Band) as a product manager and instructor for SIA and EAW.

In the course of his professional career, Jamie has taught more than 300 SIM and Smaart classes, for over 4,000 students, in over 20 countries on 6 continents. He has been the house system engineer for 4 Montreux Jazz Festivals and 6 Telluride Bluegrass Festivals, has worked with Grateful Dead, Anita Baker and Louis Miguel tours, and has been involved in hundreds of system alignments across a vast and diverse range of venues (studio to stadium) and applications (theatre, church, clubs, rock and roll tours, conventions, etc.)

What he has learned from his career so far is that the art and practice of system alignment is as varied and expanding as the people, equipment and applications that encompass the field, that training classes are always a two-way street, and that anyone that understands their tools can create new and effective ways to use them.

Michael Lawrence's love affair with professional audio began in the seventh grade, when he was left unattended in his school auditorium. After graduating from Berklee College of Music in Boston MA, he spent a few years touring independently with various artists before becoming more focused on sound system measurement, analysis and optimization. In 2019 he was adopted by audio analysis industry leader Rational Acoustics, where he works feverishly on the SPL featureset of the Smaart audio analyzer in exchange for a steady diet of graham crackers and tacos.

Election Notice

We will hold our annual officer and committee member election at our June meeting. Officers (Chair, Vice Chair, Secretary, and Treasurer) are typically nominated from the existing Committee. Committee members can be anyone interested and willing to help your section produce meetings. Officers serve for one year. Committee members serve for two years, with half electing on odd numbered years, and the other half electing on even numbered years. The current list of persons running for election, as well as other details about the election can be found HERE.

If you are interested in being an officer or serving on the committee, please contact any current officer or committee member. You must be a member or associate member at the time you assume the position. More information about Officer or Committee duties can be found at this link

PNW AES Zoom Meetings

We started holding our meetings via Zoom beginning with the April 2020 meeting. Zoom has dramatically increased our reach, well beyond our Section's geographic area. Since doing this, we've had attendees from Canada, and as far away as Indonesia, and Australia. Zoom gives the ability to record our meetings, and those recordings will be posted in our past meetings Archive. For now, video from our Zoom meetings can be found (mostly) at Dan Mortensen's YouTube channel.

We use EventBrite to manage our free tickets to meetings. You need to RSVP for yours via the following link. The Zoom URL will appear on the virtual ticket for the event. Copy it down!


When you register at EventBrite and when you enter the Zoom meeting, please use your real first and last names so we can get to know each other. You do NOT need to create an EventBrite account to register.

Please Note

In order to maintain decorum and avoid interruptions, even unintended ones, we have established a few ground rules for meeting attendees:

  1. We want to see your full name on display in Zoom at the meeting.
  2. All audience audio and video will be muted for the duration of the event.
  3. The presenter will determine if they can accept questions during the presentation, or wait until specific Q&A times, and that will be announced at the beginning of the meeting. (We often use the "chat" feature to allow attendees to ask questions when they think of them, with moderators passing them on to the presenter at the appropriate time.)
  4. Based on our experience with no-shows, we reserve the right to issue more tickets than available slots. We don't want to turn people away based on inaccurate estimates of attendance, but we do have budgetary limits to the number of slots we can make available. If we reach capacity before you log in, we regret that we have no way to expand capacity at the last minute.
  5. It would be good if you watched the chat stream during the meeting. Not only is it a way to submit questions to the presenters, but it's also a way for others to contact you personally. You have the option there to direct your comment to anyone who is part of the meeting as well as to one person in particular.

Finally, in the rare instance of behavior by an attendee that moderators believe is disruptive, we reserve the right to immediately eject such attendees.

Tea* Time Topics
every Saturday, 3:30pm (Pacific) to 6:30pm
A Virtual Zoom meeting
image linked to Former Chair Dan Mortensen started the custom of people introducing themselves at our meetings. The breadth and depth of your skills and interests led to Dan wanting a more in-depth kind of presentation but without the preparation needed for a full-on meeting.

The idea behind these events is that "Audio" is a big subject with many specialties, and at our meetings we all focus together on one subject. When we do our self-introductions as part of our meetings, it's ALWAYS fascinating to hear about the kinds of things our audience members do to manifest their love of audio.

Dan thought it would be fun to create an event where the meeting IS the audience members' descriptions of what you do, preferably with pictures/recordings/movies or whatever will help you convey to us what you're up to/interested in/want to learn more about.


The TTT meetings take place each Saturday afternoon via Zoom, and will continue for the foreseeable future, if not beyond. If things open up and people start getting busy again, we'll adjust the schedule. We've been doing this for several months now, and the topics have been varied and interesting. Here is a summary (click here) of the topics we've explored since we began in May.

Registration to attend Tea* Time Topics

You will need to register by contacting Dan via When you register, please give your real first and last name.

Note that these Tea* Time Topics events are in addition to our normal 10 times/year (not in July or August) Section meetings and not a replacement for them.

Footnote: *This is Dan's normal time for tea. You may have whatever refreshments you wish, but if you get unruly/belligerent you'll be bounced without apology.
