CATT-Acoustic

v9.1 demo download

(licensed users download updates and installations via the users' page, see your CATT-A Help | About)

The demo is free and not time-limited but it is too limited for use with any actual projects, comparing to measurements, or thesis etc.
It is meant for testing and learning without a time-limit and has no
room modelling limitations. The software assumes a very good
background in room acoustics.


 CATTDEMO.EXE  v9.1f Build 1.01 (30-OCT-2020)
self-extracting installation.

Includes CATT-A v9.1f:1.01,
TUCTv2.0f:1.01 and v1.1b:3.01

Note 1: if you have an old demo version installed uninstall it first and then also delete the old Xtra32.DAT license-file from the old
installation folder, the uninstall process will not do it since the file was added after the installation.

Note 2: in a few cases it has happened that the separate data-installer did not start when CATT-Acoustic was run for the first time.
Calculations will then fail since no Surface properties library can be found, or if not used a
Predict SxR TUCT will fail. If so, close
CATT-Acoustic and run the installed cattdemo_data.exe and after restarting CATT-Acoustic select File | Preferences and
confirm the "CATTDATA " folder and then select your Prefs.

Note 3: for those only interested in viewing v8 PLT-files, v9 PL9-files or OGL-files the standalone viewers can be downloaded instead.
