Journal of the Audio Engineering Society: 2008 Editorial Schedule

Journal of the Audio Engineering Society

2008 Editorial Schedule

The Journal of the Audio Engineering Society is a peer-reviewed journal published ten times a year. All members of the AES, as well as many nonmember subscribers, receive the Journal. Society membership is composed of professionals engaged in the theory, design, application, sales, and purchase of audio components and systems. Circulation: 13,000+.

The AES holds two major international conventions per year where technical and scientific papers are presented by academicians, electrical engineers, acousticians, sound system designers, recording/broadcast engineers, and others active in the global audio engineering community. Asterisks (*) represent special Journal coverage of these conventions.

Feature Article: DSP for Loudspeakers
Signal processing is used increasingly in loudspeakers to compensate for a range of linear and nonlinear distortion processes that typically arise. DSP can also be used in crossover design and for controlling the spatial radiation characteristics of loudspeakers or loudspeaker arrays. This requires the detailed understanding and modeling of the acoustical deficiencies and behavior of transducers and cabinets.
Feature Article: Anatomy of the Soundscape: Evolving Perspectives
This article describes a soundscape to be comprised of three basic active acoustic sources: biophony, geophony, and anthrophony. It looks at the ways in which natural soundscapes are currently thought to be linked to the fields of ecological resource management, geology, medicine, biology, physics, sociology, and many other disciplines.
Feature Article: Understanding Sigma Delta Modulation: The Solved and Unsolved Issues
Sigma delta modulation is the most popular form of analog-to-digital conversion used in audio applications; also commonly used in D/A converters, sample rate converters, and digital power amplifiers. In this tutorial, the theory of sigma delta modulation is introduced, with explanations of how performance is assessed. Some discrepancies between theoretical and experimental results are resolved. Issues of use, such as limit cycles, idle tones, harmonic distortion, noise modulation, dead zones, and stability are discussed. Practical examples are given to illustrate the concepts presented.

*Preview 124th Convention: Amsterdam, The Netherlands, May 17–20, 2008
Feature Article: Forensic Audio
Sophisticated audio processing techniques are used in the identification and authentication of recordings used in forensic analysis.Work is under way to eliminate or enhance voices in complex mixtures, for example. A remarkable new technique enables recordings to be authenticated by analyzing the electrical network frequency, which enables recordings to be given a unique time stamp.

Conference Preview: 33rd Conference on Audio Forensics—Theory and Practice Denver, USA, June 5–7, 2008
Feature Article: Automotive Audio
Automobiles present the audio engineer with unique problems that result from the small space and off-center listening position. Recent work in this field concentrates on improving the stereo image and on the development of advanced listening test systems. The problem of uneven bass reproduction in cars is tackled.

MAY March 14, 2008 March 21, 2008
Feature Article: Loudspeakers, Reflections, and Rooms
The relationship between loudspeakers and the rooms they operate in has been the topic of much debate. Recent evidence suggests that room reflections may not be as problematic as previously thought under some circumstances. However, the perceived timbre of loudspeakers can be affected by rooms and can affect listener preference decisions. What are the important factors governing the effect of such reflections on loudspeaker quality?

Conference Preview: 34th Conference, Jeju Island, Korea, August 28-30, 2008
Feature Article: Broadcast Audio
Some highlights of broadcast workshops from the 123rd Convention are presented, covering topics such as loudness and listener fatigue, as well as the art of sound effects and lip sync in HDTV.

JULY/AUGUST June 2, 2008 June 9, 2008
*Preview 125th Convention: San Francisco, October 2–5, 2008
*Convention Report: Coverage 124th Convention, Amsterdam
Feature Article: Signal Processing for 3-D Audio
A wide variety of advanced techniques are now employed to analyze and render the spatial content of audio signals. Spatial audio scenes can be encoded in novel ways and there are new techniques for extracting the ambience components from complex scenes. Many alternatives are employed for rendering such as binaural, ambisonics, ambiophonics, and wavefield synthesis.

SEPTEMBER July 14, 2008 July 21, 2008
Feature Article: Consumer Audio Networking
Audio signals are increasingly distributed around the home using computer networks, either wired or wireless. What is the current state of the art in this field and what standards exist for interoperability and control? We review the situation starting from a tutorial given by Steve Harris at the 123rd Convention.

Feature Article: Audio for Games
Game audio is a growing field in the industry. There is a new demand for music that is not fixed but that changes depending on the current action or situation in a game. What is interactive XMF and how can it be used for making music that adapts to the game play? How can game audio be adapted to work on broadband phones?

NOVEMBER September 14, 2008 September 21, 2008
Conference Report: 34th Conference, Seoul
Feature Article: Hall Acoustics and Modeling
Good hall acoustics transform the experience of listening to music, and there are good reasons why some halls are preferred to others. However, some halls have to be constructed to serve multiple purposes so they need flexible acoustic treatment. There is also a need for sound reinforcement systems that can complement the acoustics of a particular hall, particularly when the hall is also used for rock and pop music.

*Convention Report: Coverage 125th Convention, San Francisco
Feature Article: Perception and Listening Tests
Audio systems need to be optimized for human listeners. We review the most recent research in psychoacoustics from recent AES conventions, concentrating on the evaluation and optimization of perceived audio quality and on systems and methods employed for listening tests.
