The ultimate limitations to the performance of long-range sonar are due to ocean sound speed perturbations and the characteristics of the ambient acoustic noise field. Scattering and diffraction resulting from internal waves and other ocean processes limit the temporal and spatial coherence of the received signal, while the ambient noise field is in direct competition with the received signal. ...

As high-quality signal processors become more sophisticated and programmable, composers are increasingly interested in using them to transform the sounds of acoustic instruments during a live performance. This paper describes a real-time interactive program, created with MAX, that allows a performer to generate and control sound from a MIDI-controllable signal processor according to musical cue...

Fast advances in several signal processing techniques, along with cost-effective digital technologies for their implementation, are ready to address important manufacturing and machine monitoring issues for which no solution currently exists. Among new technologies are advances in wavelet and time-frequency signal analysis. By virtue of their ability to characterize both transient phenomena and...
