The Allen & Heath Real Time Analyser (RTA) is a Windows(TM) application that provides a set of tools to help the sound engineer check and calibrate any sound system.

We recommend that the RTA is run on a Pentium II 233MHz or better machine with at least 64Mb of memory and a suitable sound card and a graphics system capable of supporting 256 colours.

The RTA runs on Windows 95/98/ME/NT/2000/XP The demo period for this software will run out after 10 days. When this happens you’ll need to unlock it using the name and serial shown below:
