Presence and the Utility of Audio Spatialization
Presence: Teleoperators and Virtual Environments, 2005The primary concern of this paper is whether the utility of audio spatialization, as opposed to the fidelity of audio spatialization, impacts presence. An experiment is reported that investigates the presence-performance relationship by decoupling spatial audio fidelity (realism) from task performance by varying the spatial fidelity of the audio ...

Composition and Perception in Spatial Audio
Computer Music Journal, 2017This article discusses the advantages of spatial audio, in general, followed by strategies for applying spatial components to composition. The discussion then looks ahead to questions that may be solved by future implementations of spatial software and hardware. Despite the fact that technical systems for spatial audio have been in use since the 1950s,

Experiments in spatial mobile audio-conferencing
Proceedings of the 4th international conference on mobile technology, applications, and systems and the 1st international symposium on Computer human interaction in mobile technology, 2007With improvements in digital cellular networks, and greater pervasiveness of wireless communication, mobiles phones begin to support multi-party calling. Due to hardware limitations in current models, speakers are presented in a single audio stream, causing confusion and decipherability issues.

Spatial audio for telepresence
The Journal of the Acoustical Society of America, 1999Developments in communications technology, such as audio–visual conferencing and telepresence, have created a new set of demands for audio delivery systems. In the past, a telephone handset, with its limited transducers, was adequate for simple spoken communication; however, future multiuser communication systems and immersive machine interfaces will ...

Scalable audio coding based on spatial perception in audio surveillance
2014 International Conference on Audio, Language and Image Processing, 2014A spatial perception based scalable audio coding in audio surveillance is presented in this paper. Sudden events in audio surveillance are often accompanied with high energy, fast changing energy or sound location. Current priority schemes of scalable audio coding are mainly based on the energy criterion or perception importance criterion, in which ...

Spatial audio cues based surveillance audio attention model
2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010In this paper, we propose a bottom-up audio attention model based on spatial audio cues for unsupervised event detecting in stereo audio surveillance. Firstly, the spatial audio parameter Interaural Level Difference (ILD) is extracted to calculate and represent the attention events, which are caused by rapid moving sound source.

Surveillance Audio Attention Model Based on Spatial Audio Cues
2009For stereo audio surveillance in complex environment, we proposed a bottom-up audio attention model based on spatial audio cues analysis, and an environment adaptive normalization method. The traditional audio attention models are based on mono audio characters, such as energy, energy peak, or pitch.

Many sounds artists are now producing their work in multi-channel digital audio, utilizing powerful audio software in very fast computers, and storing sound files on large hard drives. Some works will be played in public performance directly from computer, where multi-channel sound cards are able to deliver multiple high fidelity audio streams ...
