- Reverberation time based on impulse or noise (option 10) excitation
- Calculates both T20 and T30; backward integrated decay for impulse
- Displays the graphical reverberation decay for each frequency band
- Covers the 63 – 8000 Hz frequency bands for the 1/1-octave fi lters
- Covers the 50 – 10000 Hz frequency bands for the 1/3-octave fi lters
Option 9 requires that minimum option 1 be installed.
