Client File Recorder
Just as it is possible to record audio from various patch points within the processing chain on the
actual Omnia.9 itself, you can also record audio streamed to the client PC. The recorders in the
client software work in exactly the same way. Detailed information on how to use the file recorders
can be found on Page 14 of the main Omnia.9 User Manual.
Speaker Calibration
As mentioned earlier, taking the time to calibrate at least one set of speakers to act as your
reference monitors is time well spent. In order to perform a speaker calibration, you need four
tools:
A calibrated microphone to capture the audio.
A pink noise generator to provide audio for measurement (pink noise having an equal
amount of “noise power” in each octave).
A real-‐time audio analyzer (RTA) to visually display what the microphone is hearing.
Some means by which to correct for speaker and/or room inaccuracies (such as a parametric
equalizer).
Omnia.9 provides three out of the four tools – the pink noise generator, the RTA, and the EQ. All
you need to add is the calibrated mic.
Choosing a Calibrated Mic
It is important to understand that you must use a calibrated microphone designed for sound
measurement purposes to perform a proper calibration. Studio or recording mics – even the high-‐
end, high-‐dollar ones – are of no value when calibrating a system.
You can spend thousands of dollars on a scientific-‐grade, high-‐precision calibrated microphone, but
the good news is – you don’t have to. Even the least expensive models will provide good quality
results and are worthy of consideration.
While we are not in the business of selling microphones, nor do we have any interest in promoting
any brand or model over another, we can tell you that Behringer ECM8000 works quite well and can
be purchased at local music stores and from various on-‐line vendors for under $100. If you prefer to
connect your mic via USB or Firewire, several manufacturers (M-‐Audio, E-‐Mu, and Blue come to
mind) offer XLR to USB and XLR to Firewire converters starting at under $50).
Setting Up the Mic
Place the microphone as close as possible to the position you will occupy when monitoring so that it
hears what you will hear. In cases where you are calibrating two of the same speakers, and both are
placed in similar locations in the room, you can calibrate both the left and right channels
simultaneously. If you find yourself in a situation where the speakers will be affected differently by
their individual placement in the room – one is suspending from the ceiling in a corner and the other
