13.9.1 Smaart Room Analysis Wizard
The SRA Wizard is an automated process that will guide you through the steps of acquiring a frequency-
response trace for your audio system. A frequency-response trace is the plotted result (frequency and
amplitude) of the system measurement. This measurement is calculated using Rational Acoustics’ transfer
function, which is a set of proprietary algorithms that compare the signal from a measurement mic to
computer-generated pink noise.

Frequency Response Trace
To launch the Room Analysis wizard, click on the Room Analysis tab and follow the onscreen instructions.
Click OK to start the wizard.
Next you will be asked to pick the type of analysis you would like to do. Basic Analysis requires you to take a
single measurement of your system. When analysis is complete, the wizard will continue to output pink noise
through your system while you EQ, allowing you to view the effects of your filters in real-time.
Advanced Analysis requires you to take three separate measurements and will generate a more accurate
frequency-response trace of your system by averaging the measurements together. Once the trace has been
generated, this wizard will not continue to analyze your system. To view the effects of your filters, you must
run the wizard again. Skip to the next part of this section for more information on Advanced Analysis.
Note: StudioLive RM/RML users must first select a talkback input from the talkback channel. Once selected,
this will be the input source targeted by the Smaart Room Analysis Wizard.
Basic Analysis Mic Placement
Place your microphone on-axis in front of the speaker you want to analyze. If you are analyzing a stereo bus,
place your microphone on-axis in front of the Left speaker. See Section 13.9.4 for tips in choosing the best
primary mic position.
Advanced Analysis Mic Placement
As previously mentions, you will analyze your speaker from three different positions. For the first analysis,
place your microphone on-axis in front of the speaker you want to analyze. If you are analyzing a stereo bus,
place your microphone on-axis in front of the Left speaker. See Section 13.9.4 for tips in choosing the best
primary mic position.
