Underwater Acoustic Signal Processing Workshop

Listings Underwater Acoustic Communications: Working at the Intersection of Physics, Signal Processing, and Communications Theory James C. Preisig Woods Hole Oceanographic Institution WHIO, MS #11 Woods Hole, MA 02543 [email protected] The underwater environment is widely regarded as one of the most difficult communication channels. Underwater acoustic communications systems are challenged by t...

Interactive Signal Processing for Acoustic Instruments

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...

Digital Signal Processing for Acoustic Emission

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...

A Platform for Collaborative Acoustic Signal Processing

In this paper, we present a platform for collaborative acoustic signal processing, and demonstrate its use with an example application. Our platform is built upon the Stargate Linux-based microserver, and supports synchronized multi-channel acoustic data acquisition. We implement a dataflow-like staged event-driven programming model within the Emstar software framework that simplifies the devel...
