The Waterfall and Directivity give CLIO 10 the possibility of making 3D or Color plots by adding a third dimension (time or degrees) to classical amplitude-frequency graphs. Waterfalls are used to characterize the anechoic sound decay of a loudspeaker or the sound decay in a room.  
 

The Waterfall post processing permits the following 3-D or Color types of analysis:
- Cumulative spectral decay (CSD)
- Energy Time Frequency (ETF)

 
 
 
 

Directivity analysis characterizes the radiation of a loudspeaker versus vertical or horizontal angle.

The Directivity post processing permits the following analysis:
- 3-D directivity (waterfall like)
- Color map directivity
- Classical polar plots
