Description The APx500 CSD Utility is a Windows application for making a Cumulative Spectral Decay (CSD) plot, sometimes referred to as a waterfall plot, from the measured impulse response of a loudspeaker.

The APx CSD utility also requires the SPK-RD or UTL-CSD software option to be installed on the connected APx audio analyzer.

If you require a SPK-RD software option, please contact your Audio Precision sales representative. This version of the utility works with APx500 versions numbered v10.0.x.
