Proceedings of 1997 Workshop on Applications of Signal Processing to Audio and Acoustics.
Advanced Audio Coding (AAC), part of ISO/MPEG-2, issued as an international standard in April, 1997. It supports single or multiple channel audio programs and delivers excellent audio quality at or below 64 kbps/channel by exploiting the compression

An enhancement to sound field reconstruction is proposed which improves subjective spatial perception and widens the sweet spot size of a 5 channel surround system. With the popularization of multi-channel audio systems, consumers have access to arti

An algorithm for covert digital audio watermarking is presented. The method embeds a low-rate (in the neighborhood of 20–30 b/sec) watermark via perceptually insignificant long term multiband phase modulation, The watermark is very difficult to eit

Better reproduction of sound is achieved analyzing audio signals for perceptual soundfield imaging cues, and applying appropriate portions of the audio signal to a directional speaker and to a diffusing speaker, based on the analyzed audio signals. S

A sound-capturing arrangement uses a set of directional microphones that lie approximately on a sphere having a diameter of 0.9 ms sound travel, which approximates the inter-aural time delay. Advantageously, one directional microphone points upward,

A technique for the masking of quantizing noise in the coding of audio signals is usable with the types of channel coding known as "noiseless" or Huffman coding and with variable radix packing. In a multichannel environment, noise masking thresholds

The quality of sound pickup in large rooms—such as auditoria, conference rooms, or classrooms—is impaired by reverberation and interfering noise sources. These degradations can be minimized by a transducer system that discriminates against sound
