If you've never used Smaart, it's worthwhile reviewing the resources available from the Rational Acoustics web site, particularly the PowerPoint presentation and basic setup guide. I ran Smaart on a MacBook 2 GHz Core 2 Duo/4 GB RAM with Digi 002R and MOTU Traveler interfaces. Rational Acoustics recommends at least a 2 GHz dual-core processor and Smaart is compatible with CoreAudio, WAV or ASIO audio drivers.
The latest revision of Rational Acoustics' Smaart is v7.1 which runs under Mac OSX (10.5 or 10.6) as well as Windows 7, XP, or Vista.
Editor's Note: Steve submitted this as his regular 'On the Digital Edge' column for the January issue of FOH but, as it is a pretty extensive look at the nuts and bolts of a much-used software program, we are running it as a Road Test instead.
