Directivity functions of musical instruments

On this page you find data on directivities of symphony orchestra instruments.

A Matlab GUI for analyzing instrument directivities

The registered users can download from the link below a Matlab package, which contains an interactive GUI for visualization directivities of all common symphony orchestra instruments. The GUI is initialized and started by running the script 'startGui.m'. See also README.TXT for more information. The presented measurement system as well as analysis of all instruments are presented in

Instrument directivity data in CLF format

The second file below consists of directivity data in CLF format which is used in several room acoustics modeling programs. The derivation of the CLF data is described in the following paper:
