he deep changes that have affected aural perception since the late 19th century may be reduced to a common denominator: loudspeaker-mediated listening. In the earlier half of the 20th century, we encounter the influences and effects of such changes in countless reflections and practices, which I introduce through a metaphoric image of the loudspeaker and its sides: on one side, the listener, wh...

Binaural audio requires the use of crosstalk cancellation if reproduced using loudspeakers. A three-listener system has been designed and built as part this work. Simulations for different loudspeaker distributions are presented a large span is shown to increase low-frequency performance while denser distribution in front given listener increases mid high-frequency cancellation. The system's un...

Public-address system has been widely used in many applications to amplify speech and music signals. In such environments, an acoustic feedback from a loudspeaker to a microphone usually exists and it may causes howling which explosively increases a certain frequency amplitude. The howling is a persistent and an annoying problem in many acoustic enviroments. To solve this problem, we have previ...

Within a general framework for seamless acoustic man-machine interfaces, common problems for different classes of applications are identified. Removing loudspeaker echoes, noise, and reverberation of local sources from microphone signals, and conditioning loudspeaker signals to eliminate reverberation and noise at a listener’s ears constitute problems of system identification and signal separat...

One of the greatest challenges facing any composer of spatial electroacoustic music is how to adapt their work to different loudspeaker systems, their associated software interfaces, and their implied performance practice. Various multi-channel tools exist which can be adapted for different types of symmetrical arrays, however, these are generally entirely incompatible with the diverse orchestr...
