Event description

Description

The world of music production is rich with subjective opinions and attractive marketing. On this night, we will focus on how to take and read measurements for an objective understanding of the gear we use. We will also show you how to submit your results for a poster or a paper in the AES journal.

Topic 1:

At the 143rd AES a resistor manufacturer's booth sign about the "best resistors for audio" led to an in-depth look at what characteristics resistors actually have that would affect an audio system and how those could be measured. Sounded simple enough but dozens of measurements later there are more questions than answers. We'll review noise and distortion in electronics, the test fixture design, the measurement tool, and some initial results. The presentation will close with a list of potential side projects that may be of interest to AES student members looking for topics for papers or poster sessions.

Brewster LaMacchia has been involved with DSP and audio through a succession of companies. Previously with Momentum Data Systems he worked on playback systems for consumer 3D audio (ATMOS & DTS:X). MDS hardware & software system products are found in many high-end home theater pre-processors; MDS software is found in mass market multi-channel consumer audio products. Currently, with a new company, Clockworks Signal Processing LLC, he's focused on open source modular hardware for audio signal processing. Outside of work he's active in area astronomy clubs and regularly organizes star parties for the public to observe through volunteer's telescopes.

Topic 2

Organizations like the Audio Engineering Society promote scholarly research through their journals, conferences, and conventions. Conducting research projects of your own and presenting the results can help move the industry forward, and advance your own career. In this session, we'll take a quick look at the opportunities that are available, and how you can get involved!

Bradford Swanson is active as an educator, engineer, and musician in the Boston area. He's served as adjunct faculty at Tufts University and University of Massachusetts, Lowell, and presented guest lectures and papers at Berklee, NYU, WPI, University of Michigan, Carnegie Mellon University, NESCOM, and multiple AES conferences and conventions. As a product manager for iZotope, he's contributed to multiple award-winning projects, including Iris 2 and RX 6. He has also worked extensively as a musician and engineer with The Bad Plus, The Jazz at Lincoln Center Orchestra, Regina Carter, Mason Jennings, and many others.
