This document will aid those wishing to understand the coordinate system used for loudspeaker data.
The following file will serve as examples of the loudspeaker data provided by ETC, Inc.
To view the CLF data, you will need to download and install the freeware CLFViewer (http://www.clfgroup.org/clfdocuments.htm). Follow the first link on the page (End Users Kit).
To view the EASE data you will need any current version of the EASE room modeling program (www.renkus-heinz.com/ease/index.html)
NOTE: These data files were created from the same set of impulse responses, and allow direct comparisons between the EASE and CLF file formats.
