Manual adjustments can be made to the correction process. The plugin shows the blue source plot overlaid with a correction curve (green), target curve (red), output curve (purple), correction limits (yellow) and correction filter phase (orange). Once done, you're presented with a plot that you save as a Sonarworks Project file (.SWPROJ) and load into the Reference 3 plugin, which is inserted across your monitor outputs.
The calibration process is partly automated, as the onscreen graphic indicates where you should put the mic and senses when you've done so so all you have to do is get the mic into the target area. Then there are 24 positional tests (all taken around the location of your head in its normal listening position). The first set of tests generates measurement data for the distance between the two speakers and your distance from the speakers (these can be edited manually).
