Digital Audio Educational CD Released

This new educational CD, produced by the AES Technical Committee on Signal Processing (TC_SP), is intended primarily to address issues relevant to digital signal processing algorithm designers and implementers.

Digital audio systems have obviously become ubiquitous in recent years, due in large part to the ingenuity and effort of Audio Engineering Society members. The maturity of the digital audio signal processing field can present a serious challenge for new students, researchers, software engineers, product testers, and other newcomers who must try to understand the relevance and relative importance of various signal processing parameters without being able to hear and see the details and effects: simply reading a written description is not the best way to learn and understand audio processing issues.

Since a typical characteristic of audio digital signal processing algorithms is the need for sustained, uninterrupted processing, even a single sample dropout or parameter update error can result in an audible artifact. Detecting, diagnosing, and correcting this sort of implementation error often requires experience listening for the defects, and examples of this type are included on this CD. The examples on this disc are intended to demonstrate a variety of the effects, both good and bad, that digital audio signal processing engineers are likely to come across in their work.

AES Continues Oral History Project

Initiated during an Audio Engineering Society Historical Committee meeting in 1997 by long-time member Irv Joel, the AES Oral History Project was envisioned as a personal record of the creative and technical thought process of the doyens of professional audio. "This AES Oral History Project was initiated as an inspiration to new generations of audio industry professionals," explains AES executive director Roger Furness. "Education remains an AES priority, and these unique DVD personal histories represent a priceless link between the past contributions of our worldwide membership and the on-going innovations of our rapidly evolving future.

"Irv Joel has had close, long-standing relationships with many of the giants of our industry," he continues. "In addition to co-ordinating the interviews, he served as cameraman and off-camera interviewer for the greater part of them, a massive undertaking. The entire professional audio community owes him a vote of thanks for producing over 100 irreplaceable one-on-one interviews."

In 2007, after 10 years of shooting with a basic lighting kit, two lavalier mics and... (continued at following link)

AES Publishes Monograph on Binaural Technology

Binaural Technology

Binaural Technology

Rozenn Nicol has been investigating Spatial Audio technology at Orange Labs for more than ten years. With the publication of this monograph, she aims to promote a better understanding of how binaural technology really "works". Despite its straightforwardness the reproduction of binaural audio with headphones is always impressive - a really convincing 3D sound scene is achieved. This is possible because binaural technology merely mimics the spatial encoding that we use daily when we localize sounds in real life.

Starting from practical issues, concerning what is the real meaning of sound recording and rendering for binaural technology, the underlying theory is then progressively examined. The diffraction of the acoustic wave by the listener's body defines the key concept of binaural technology and can be represented by the associated transfer functions, which are known as Head Related Transfer Functions (HRTF). HRTFs are therefore the raw material of binaural spatialization. It is shown how the spatial information is conveyed through HRTFs, investigating both physical phenomena and auditory localization mechanisms.

Special attention is given to binaural synthesis which consists in simulating the left and right signals as they would have been recorded by a pair of microphones inserted in the listener's ear. This is one of the most well known applications of binaural technology, since it allows one, to create with full control a virtual auditory space for psychoacoustic experiment or virtual reality purposes. by straightforward filtering.

Although binaural technology is a powerful tool for sound spatialization, it should be kept in mind that, as the spatialization is determined by the listener's morphology which is unfortunately strongly individual, the spatial encoding of a sound scene is theoretically valid for one sole individual. The monograph ends with an overview of solutions for adapting the binaural spatialization process to an individual’s variability.

Section Meeting Recordings Now Available

The AES Regions & Sections and Membership Committees have been collaborating on a pilot project to make available recordings of section meetings to current AES members. The first six of these are now available, attached to meeting reports on the AES website. A brief summary is provided below. We are aware that some sections make recordings of their meetings available in various forms, on their own websites, but this is an attempt to bring selected meetings to the attention of the wider AES community. We hope to bring you further section meeting recordings over the coming months as more sections begin to take part in the project. Thanks are especially due to Theresa Leonard and David Bowles for their hard work during this pilot phase.

Francis Rumsey, Chair, Regions and Section

  1. Vancouver: ‘Education working with Industry panel discussion’, with Theresa Leonard (Banff Center), Bob Grieve (VFS Sound Design), Chad York (Next Level Games), Frankie Mann (DTS), Mark Scott (Post Modern Sound), & Warren Brown. (Audio only)
  2. San Francisco: John Paulson and James Arntz discuss the documentary ‘Les Paul, Chasing Sound’ with David Bowles. (Audio only)
  3. Boston: ‘Building an Audio Plug-in: From Concept to Release Date’, Jeremy Todd - iZotope, Inc. (Audio and video)
  4. British: ‘Maintaining audio-video sync in today’s broadcast environment’ (Audio only)
  5. British: ‘An interview with Neville Thiele’ (Audio only)
  6. British: ‘From hi-fi to PA: predicting and measuring what we hear’, Peter Mapp. (Audio only)

More recordings will be added to our podcasts page over the coming months

Call for Board of Governors Nominations

The Nominations Committee is at this time soliciting the names of members to be considered for possible inclusion in the 2010 ballot for election of officers to the Board of Governors. To aid us in this task, please let us know if there is someone you would like us to consider for this election.

To be eligible for nomination, a candidate must be a voting member of the Society and belong to one of the following membership categories: honorary member, fellow, or member, and must be willing and able to attend the meeting of the Board of Governors each year.

Nominations must be received by February 22, 2010 and can now be submitted online.

AES Now Accepting Online Awards Submissions

Nominees are presented by the members and officers of the AES to the Awards Committee on a continuing basis. In addition, AES Section Chairs are hereby requested to send in names of outstanding local section members.

The Awards Committee will consider the nominees, validate credentials and contributions, confirm the award categories, and prepare a slate of recipients to be voted on by the Board of Governors. Approved awards will be presented at a special ceremony during forthcoming AES conventions.

The committee is eager to learn of all those who deserve recognition in the audio field. New for 2009 is the ability to submit a candidate online instead of mailing in a PDF.

Best Practices in Network Audio

Analog audio needs a separate physical circuit for each channel. Each microphone in a studio or on a stage, for example, must have its own circuit back to the mixer. Routing of the signals is inflexible. Digital audio is frequently wired in a similar way to analog. Although several channels can share a single physical circuit (e.g., up to 64 with AES10), thus reducing the number of cores needed in a cable. Routing of signals is still inflexible and any change to the equipment in a location is liable to require new cabling.

Networks allow much more flexibility. Any piece of equipment plugged into the network is able to communicate with any other. However, installers of audio networks need to be aware of a number of issues that affect audio signals but are not important for data networks and are not addressed by current IT networking technologies such as IP. This white paper examines these issues and provides guidance to installers and users that can help them build successful networked systems.
