Precision EQ Software for Windows


Parametric equalization made easy
There's a new equalization technique on the market, and it offers sound engineers the very latest in sound analysis technology. Introducing PrecisionEQ software, a program to use with the TEF analyzer and a parametric equalizer. Sound Lab PEQ provides a simultaneous display of the unequalized sound system frequency response, the inverse of the equalizer electrical response and the equalized response in the room.
With PrecisionEQ, the sound engineer can equalize a sound system to a high degree of accuracy in much less time than with traditional equalization techniques. In addition, since only minimum phase regions can be equalized, PrecisionEQ offers a mode allowing you to highlight those regions on the equalized graph.
 
 
Incredible accuracy, incredible ease
With PrecisionEQ software, a TEF analyzer, and a parametric equalizer, you can quickly and accurately equalize a sound system, accomplishing in a matter of minutes what may have taken hours with real time analysis.
Using the precision equalizer, you match the response of the inverse equalizer curve to the unequalized curve of the system. This results in a much flatter equalized curve.
 
 
Precision and flexibility
PrecisionEQ software provides you with greater accuracy than traditional real time analysis. The software allows you to view the precision adjustments capable with a parametric equalizer. The result is superior performance of the sound system.
PrecisionEQ and a TEF system create a very powerful package for sound analysis, making the equalization process fast, easy and accurate.
