Digital Audio Represents More than Half of the Papers Presented

NEW YORK, August 8, 2001-Recognizing the audio industry's continuing shift towards the digital domain, more than half of the AES 111th papers sessions, took place November 30 - December 3 at the Jacob Javits Convention Center, we occupied by the increasingly significant topic of digital audio.

'It's worth noting that this year's papers sessions on digital items make up more than half of the program,' says Jim Johnston, 111th papers chair. 'Signal processing and loudspeaker design are the most common subject. Human perception, which was a non-starter 10 years ago, is in a close third place.'

Signal procession ranges from applied tutorials by Duane Wise on the innards of DSP, to room correction and synthesis. Multichannel audio is also very well represented this year, with several presentations of new work on both synthesized and captured sound stages, perceptual analysis of reverberation, and examination of listener preference

A variety of validiation tests headlines the psycho acoustic sessions, from auditory modeling to loudness and spatial perception, tying in very closely with the work in multichannel audio.

There were two sessions focusing on signal processing for audio, two on loudspeakers and two on psychoacoustics and audio testing. Additional session topics included low-bit rate (perceptual) audio coding, multichannel sound, watermarking and internet audio, instrumentation and measurement, room acoustics and sound reinforcement, microphones, analysis and synthesis of sound, spatial perception and processing, and automotive audio.

Paper sessions were scheduled to take place both in the mornings and afternoons during the convention. For more information on the 111th Convention, please visit the AES website at or contact the AES Headquarters at (212) 661-8528 or via e-mail.
