All new production MS-3 Music Servers will come with MathAudio Room EQ installed with Foobar2000. This will allow users to try room and speaker correction for two channel audio replay with any file played back with Foobar2000.
The Room EQ component in the DSP processing section has three modes, Measurement, Run and Bypass. Measurement and Run are as expected from the name. Bypass allows the user to hear the original system without the processing for direct comparisons to correction.
For measurements, I recommend a Dayton Audio UMM-6 USB calibrated mic as it is very easy to get running with the system and make measurements of the room from the listening position with a user supplied mic stand or small tripod that comes with the mic kit. Has a 15' USB cable to connect to the MS-3 for movement capabilities. It is best to use a long video cable, like HDMI to remote the computer if needed to have the mic in the listening position.
Here is a screen capture of the Room EQ display in Foobar2000 on some DIY speakers. Shows the measurement and corrected response for it's processing of the single position measurement I made. It can average up to 20 measurements if the users has interest in a wider corrected area.
