Novel Software Tools for Research and Musical Applications
This project began with an interest in gradually developing devices to help address common stimulus needs for our auditory perception laboratory’s research studies, along with some developed curricular experiences for students involving tone synthesis. It was soon realized that many of the synthesis tools and principles being developed would be of interest to both auditory researchers and electronically-based musicians. The project has grown to a family of devices under development, and some of these are now being made available. We also have been working collaboratively with researchers from other laboratories to help deliver devices that meet their research needs.

Hardware: Acoustic Filter Designs for Musical Instruments
Following from the laboratory’s ongoing interests in software development to evaluate the contributions of vibrational sources and filter resonances to event perception (e.g., see above), we recognized that it also should be possible to realize a corresponding set of acoustic band-pass filters that, unlike traditional approaches, mechanically accomplish dynamic changes in filter settings. This ongoing work is being done collaboratively with JMU’s Tom Wilcox, who is helping to realize designs (e.g., as CAD drawings), as well as generate functional prototypes through 3-D printing and working by hand with other equipment and materials. The resulting products are expected to be of interest to not only educators in audition and sound, but also to musicians once the filters are integrated within acoustic musical instruments.
A proposal reflecting a range of initial hardware filter designs was recognized by a university-wide Intellectual Property Disclosure Incentive Program award. Read More
