Abstract:

AcMus is an integrated software platform for musical room acoustics. A preliminary version of the software was developed as a MATLAB prototype of acoustical analysis functions. The prototype processes measurements recorded from a room and outputs calculations that help us assessing thequality of the room for musical performance. We have measured a number of musical rooms ourselves and are currently analyzing the data. Meanwhile, we are working on the final implementation of the AcMus integrated platform, which is based on a flexible and extensible Java plug-in framework. This new, open source version of the system incorporates our experiences with the preliminary prototype and tries to maximize the usability and effectiveness of the user interface.
