MEETING CONTENT:

The Central Indiana AES is pleased to welcome Bill Whitlock to Indianapolis for an in depth discussion regarding audio syatem grounding and interfacing.  Bill will share his knowledge and experience, revealing the true causes of system noise and ground loops. Unbalanced interfaces are exquisitely vulnerable to noise due to an intrinsic problem . Although balanced interfaces are theoretically noise-free, they’re widely misunderstood by equipment designers, which often results in inadequate noise rejection in real-world systems. Because of a widespread design error, some equipment has a built-in noise problem . Simple, no-test-equipment, troubleshooting methods can pinpoint the location and cause of system noise. Ground isolators in the signal path solve the fundamental noise coupling problems. Also discussed are unbalanced to balanced connections, RF interference, and power line treatments. Bill will also point out some widely used “cures” that are both illegal and deadly.

Bill Whitlock has designed analog electronics since 1972, serving as chief electronics engineer for Quad-Eight, Laserium®, and Capitol Records prior to joining Jensen Transformers in 1989 after Deane Jensen’s untimely death. His writings have been published in the AES Journal, Glen Ballou’s “Handbook for Sound Engineers,” Doug Self’s “Audio Engineering Explained,” nearly all Jensen white papers, and numerous magazine articles. Bill is also active in standards work for AES, UL, IEC, and CEA.

His four patents include the InGenius® balanced line receiver IC and the ExactPower® high-speed, waveform-correcting AC voltage regulator. He’s a Life Fellow of the AES and a Life Senior Member of the IEEE.

Please RSVP if you intend on coming and feel free to bring non-AES members, all are welcome.  We look forward to seeing you there. Attendance is free but seating is limited to 150, so please RSVP

Meeting Report: Dinner at Shapiro’s Deli & A Tour of Lucas Oil Stadium

The Central Indiana Section of the Audio Engineering Society recently held its first summer meeting on June 26, 2012 with a near-record attendance of almost 30 members! The first part of the meeting featured dinner hosted at Shapiro’s Deli courtesy of the Section for members which was certainly a hit with everyone in attendance, followed by a tour of Lucas Oil Stadium.

That’s right, dinner and a tour! The tour was courtesy of the Lucas Oil Stadium Sound & Lighting Department’s very own Floyd Paulsen with assistance from systems integrator and friend of the Central Indiana Section ESCO Communications.

Click the rack of amplifiers to view more pictures!

Floyd took the section on a compressive tour of the stadium, including the field level where he discussed the complex system of speaker arrays and delays in the bowl, one of the amazing amplifier rack rooms, the press box, and the video and audio production suites. Along the way the section also received demonstrations of the Media Matrix and Crown Hi-Q operating systems which were in use throughout the installation.

The meeting was absolutely a must-attend for anyone interested in live production and installed sound and we are very thankful to Floyd, Lucas Oil Stadium Sound & Lighting, and ESCO Communications for their generosity and support of the section. Those interested can find a digital version of the handout distributed at the meeting here on ESCO Communications website.

“Voices from the Grave” Unveiled In Guest Lecture At IU Jacobs School of Music

The Central Indiana Section of the Audio Engineering Society is pleased to bring this exciting announcement to all our members. The Department of Recording Arts in the Jacobs School of Music is delighted to welcome Dr. Patrick Feaster as special guest lecturer this coming Wednesday evening, April 18 at 5:00pm in Sweeney Hall, Room M015 of the Simon Building on the IU Bloomington campus (map).  His presentation is entitled “Voices from the Grave (1850s – 1890s): Recent Discoveries in Archeophony.”

A special feature of his presentation will be the unveiling of phonautograms recorded exactly 152 years before, to the day, on April 18, 1860.  These recordings remained mute for over one and a half centuries and have never before been heard in a public venue.

Two-time Grammy nominee Patrick Feaster is one of the world’s leading researchers specializing in the early history of recorded sound.   His investigations have helped unearth dozens of significant, heretofore unknown historical artifacts containing aural information captured 120 to 160 years ago.  He has also developed revolutionary methods to recover these ancient sounds and make them audible, in some cases for the first time since they were recorded in the nineteenth century.

In his presentation, Dr. Feaster will discuss and play examples from several of the recent archeophonic expeditions in which he has played a central role, including:

  • Newly identified wax cylinders recorded in Europe in the 1880s by William J. Hammer and Theo Wangemann, pioneering recording engineers who worked for Thomas Edison.
  • Phonautograms created in Paris in the 1850s and 1860s by French inventor Édouard-Léon Scott de Martinville utilizing a stylus to etch patterns in soot-covered paper.  The discovery these scientific artifacts and successful eduction of their audio content by Feaster and his colleagues at FirstSounds.org stunned scholars and forced the rewriting of the history of sound recording to acknowledge Scott, and not Edison, as the father of recorded sound.  These revelations were profiled in The New York Times and on National Public Radio.
  • Audio recovered from paper prints made in the late 19th century, inked from the surfaces of metal phonographic discs that have since been lost to history.  Some of these prints were published in popular magazines of the era and Dr. Feaster has developed innovative techniques to educe the sounds contained on those discs from their printed images.

Patrick Feaster’s rigorous research, technical ingenuity, passion for all things audio and sheer tenacity have combined to unlock a vast wealth of ancient human sonic expression – musical instruments, acting, singing, oration and more – captured well over a century in the past and at last, available again for all to hear, study and enjoy.
