    Project Number: FB IQP HB10 HIGH BANDWIDTH ACOUSTICS – TRANSIENTS/PHASE/ AND THE HUMAN EAR An Interactive Qualifying Project Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE In partial fulfillment of the requirements for the Degree of Bachelor of Science By Samir Zutshi 8/26/2010 Approved: Professor Frederick Bianchi, Major Advisor Daniel Foley, Co-Advisor Abstract Life over 20 kHz has been a debate that resides in the audio society today. The research presented in this paper claims and confirms the existence of data over 20 kHz. Through a series of experiments involving various microphone types, sampling rates and six instruments, a short-term Fourier transform was applied to the transient part of a single note of each instrument. The results are graphically shown in spectrum form alongside the wave file for comparison and analysis. As a result, the experiment has given fundamental evidence that may act as a base for many branches of its application and understanding, primarily being the effect of this lost data on the ears and the mind.

  • Historical Development of Magnetic Recording and Tape Recorder 3 Masanori Kimizuka
    Historical Development of Magnetic Recording and Tape Recorder 3 Masanori Kimizuka ■ Abstract The history of sound recording started with the "Phonograph," the machine invented by Thomas Edison in the USA in 1877. Following that invention, Oberlin Smith, an American engineer, announced his idea for magnetic recording in 1888. Ten years later, Valdemar Poulsen, a Danish telephone engineer, invented the world's frst magnetic recorder, called the "Telegraphone," in 1898. The Telegraphone used thin metal wire as the recording material. Though wire recorders like the Telegraphone did not become popular, research on magnetic recording continued all over the world, and a new type of recorder that used tape coated with magnetic powder instead of metal wire as the recording material was invented in the 1920's. The real archetype of the modern tape recorder, the "Magnetophone," which was developed in Germany in the mid-1930's, was based on this recorder.After World War II, the USA conducted extensive research on the technology of the requisitioned Magnetophone and subsequently developed a modern professional tape recorder. Since the functionality of this tape recorder was superior to that of the conventional disc recorder, several broadcast stations immediately introduced new machines to their radio broadcasting operations. The tape recorder was soon introduced to the consumer market also, which led to a very rapid increase in the number of machines produced. In Japan, Tokyo Tsushin Kogyo, which eventually changed its name to Sony, started investigating magnetic recording technology after the end of the war and soon developed their original magnetic tape and recorder. In 1950 they released the frst Japanese tape recorder.

STOCKHAM, JR. 1933–2004 Elected in 1998 “For contributions to the field of digital audio recording.” BY ALAN V. OPPENHEIM THOMAS G. STOCKHAM, JR., professor at the University of Utah and widely regarded as the father of digital audio, died on January 6, 2004, at the age of 70. Professor Stockham was born on December 22, 1933, in Passaic, New Jersey. Tom was elected to the National Academy of Engineering in 1998. His career was strongly influenced by his love for teaching, music, perfection, and family and by his incredible skills as an engineer. He received all of his degrees in electrical engineering at the Massachusetts Institute of Technology and was appointed as an assistant professor at MIT in 1959. In the mid-1960s he joined the research staff at MIT’s Lincoln Laboratory, and in 1968 he joined the faculty at the University of Utah where he helped establish its computer science department. Early in his academic career at MIT, Tom worked closely with Amar Bose, founder of Bose Corporation, on the use of digital computers for measurement and simulation of room acoustics and for audio recording and enhancement. Through this work he became a pioneer in the field of digital signal processing, a technology that in the 1960s was totally impractical for real-time applications since the processors could fill (and heat) a room, and clock speeds were extremely slow by today’s standards. It was partly through Tom’s pioneering work on digital signal processing algorithms that this technology eventually emerged as critical to virtually all modern communication and multimedia systems.

  • Bouchard, Justin
    Bouchard 1 Justin Bouchard Dr. Bruce Simon/Dr. James Davis INDS 690-Research 11 December 2012 Older Technological Sound Recording Mediums: Problems of Preservation and Accessibility The evolution of sound recording technology has made capturing and preserving audio simple. So why is our musical heritage largely inaccessible or unavailable? The art of preserving a recording of sound and playing it back has only been around since 1877. According to the St. Louis Symphony Orchestra artistic advisor and creative chair Tim Page: “It is sometimes said that the human race is losing its sense of the past” (5). It would be terrible if we lost nearly a century and a half of our past recorded musical heritage, preserved on various mediums. Many, including cylinders and early 78 discs, are decomposing and/or broken. Due to strict and muddy United States copyright laws, many early sound recordings have disappeared forever. Books, films, even sheet music published before January 1, 1923 are available in the public domain in the United States. The same cannot be said for sound recordings made before January 1, 1923. Until February 15, 2067, no sound recordings made before 1972 will enter the public domain in the United States. By the time of the copyright expiration date, many of our earliest sound recordings may be lost due to deterioration. This date may well be “the day the music died” (Sharp 310). Despite these obstacles, many sound archivists and engineers have taken matters into their own hands to preserve our musical past. Using state of the art digital technological Bouchard 2 means, these individuals have made a small sampling of sound recordings available from almost total obscurity and disintegration.

  • 2017 New York, NY © 2017 - Mike Rivers
    Audio Engineering Society 143rd Convention Report October 18-21, 2017 New York, NY © 2017 - Mike Rivers This year’s US AES convention was back in New York for, with a few new twists. NAB’s (National Association of Broadcasters) main show is in Las Vegas in April, but for many years, they’ve held a smaller show in New York in the Fall. This year, and for at least next year as well, AES and NAB, while maintaining separate shows and identities, operated concurrently in the Jacob Javits Convention Center, sharing registration to the extent that exhibit badges for one show, which include workshops conducted on the exhibit floor as well as some special events, were honored for the other show. I believe that the intent was to encourage cross-pollenization between the audio and video communities, giving the NAB folks better exposure to pro audio products and techniques, and giving the AES folks better exposure to new opportunities in audio-for-video (primarily, it seems, in immersive video). Neither I, nor the few exhibitors I spoke with on the subject, saw very many NAB badges in the AES exhibit area, and I only did a quick run-through of the NAB exhibit area myself so I didn’t see too many AES badges there. But I think the concept has merit, and they’ll have another go at it next year. AES conventions have always been about education, and this year, the show floor presentations were expanded substantially. The Project Studio Expo stage had three full days of programming while a second stage had three full-day Expo programs - Broadcast Audio, Broadway Sound, and Live Sound.
