    New toys & tricks

    I've been experimenting with some measurement and equalization tools.

    I got a Dayton Audio OmniMic System for Parts Express, (here).
    This is a fairly impressive tool for measuring room responses.



    I've only begun to investigate its capabilities, but the first thing I did was measure my stereo's frequency response from my listening position. This was my initial measurement ...



    The other toy I'm fooling with is the Electri-Q equalizer from Aixoustinc, (here). I'm using the free version that works with my Foobar2000 player using the George Yohng VST wrapper component.

    After a while of trying different EQ settings in Electri-Q I have settled for now on this EQ filter scheme ...



    I worked interativel with OmniMic to develop these settings, and the following is my pro temp, EQ's result ...



    A smoother, flatter response should be possible with a little more fooling aroung, and perhaps using steeper EQ filters. Presently I'm using 12 dB/octave filters but Electr-Q supports 24 as well as 6 dB/octave filters.

    My system was a still is pretty flat between 200 - 2000 Hz which is doubtless important for its good sound. However getting rid of the bass hump around 70 Hz and leveling around 3000 Hz has made the bass much more natural and helped the mid-range too; notably voices in large choral works are more separated and intelligable.

    What are you using to power the mic? I was under the impression it needs a phantom power supply.

    Are you plugging it directly into your PC/Laptop and using the included software to generate the graphs? If no, what software are you using?

    Have you considered using your mic with REW (Room Equalization Wizard) from Home Theater Shack?

    Good questions. The mic is USB powered and plugs directly into the computer. The OmniMic system includes all its own software.
