Spatial Audio and Room Acoustics
The Journal of the Acoustical Society of America, 2011Schroeder’s interest in the behavior of sound in small enclosures eventually lead to the use of statistical methods of digital signal processing to estimate and track a room’s response for echo control. He showed that a small frequency shift (5 Hz) in a loudspeaker-enclosure-microphone system could be used to mitigate the coupling feedback in public ...

Spatial audio technology for telepresence
BT Technology Journal, 1997As people start to exploit new telepresence technologies to meet and work, they will be able to exploit all of their senses as they transmit, receive, and monitor information. An essential part of such three-dimensional spaces is the audio landscape. People are able to detect a wide variety of sounds and separate them in space.

Mobile spatial audio interfaces
Proceedings of the 9th international conference on Human computer interaction with mobile devices and services, 2007For an increasing amount of people (especially young people), the mobile phone, and not the computer, is becoming their main media device and portal to the virtual world. Mobile phones have become a ubiquitous technology and for many people an important tool for communication and information access.

Spatial audio conferencing system
The Journal of the Acoustical Society of America, 2010An audio conferencing system includes sending a signal of a sound at a sound location to a listening location. The system further includes establishing a relationship between a virtual listening location and a virtual sound location. The system processes the signal to provide a sound at the listening location seeming to have an analogous relationship ...

Audio spatial equalization system
The Journal of the Acoustical Society of America, 1992A television receiver includes a stereo amplifier having separate bass, treble and gain controls, for driving left and right channel loudspeakers. Separate bandpass circuits supply portions of the respective channel signals for phase inversion and feed back to respective summation circuits in the outputs of the corresponding opposite channel to produce

Audio Spatial Environment Engine
The Journal of the Acoustical Society of America, 2011An audio spatial environment engine is provided for converting between different formats of audio data. The audio spatial environment engine (100) allows for flexible conversion between N-channel data and M-channel data and conversion from M-channel data back to N’-channel data, where N, M, and N’ are integers and where N is not necessarily equal to N’.

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 ...

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.

Audio channel spatial translation
The Journal of the Acoustical Society of America, 2010M audio input channels, each associated with a spatial direction, are translated to N audio output channels, each associated with a spatial direction, wherein M and N are positive whole integers, M is three or more, and N is three or more, by deriving the N audio output channels from the M audio input channels, wherein one or more of the M audio input ...
