60 Chapter 5 EQ
Using the Analyzer
When you turn on the Analyzer, the Channel EQ shows a real time curve of all
frequency components of the signal as the audio plays, superimposed over the EQ
curves you set, using a Fast Fourier Transformation (FFT). The Analyzer curve uses the
same scale as the EQ curves, allowing you to easily recognize important frequencies in
the audio and use the EQ curves to raise or lower them.
As soon as the Analyzer is activated, you can change the Analyzer Top parameter,
which alters the scaling of the FFT Analyzer, on the right side of the graphic display. The
visible area represents a dynamic range of 60 dB, but by click-holding and vertically
dragging, you can adjust the maximum value between +20 dB and –40 dB. The
Analyzer display is always dB-linear.
When choosing a resolution from the menu, keep in mind that the higher the
resolution, the more CPU power is required. High resolution is necessary whenever you
need reliable results in very low bass frequencies, for example. The bands derived from
FFT analysis are divided in accordance with the frequency linear principle, meaning
that there are more bands in higher octaves than in lower ones.
Note: The FFT Analyzer needs additional CPU resources. In fact, CPU usage increases
significantly at higher resolutions! It is recommend that you disable the Analyzer or
close the Channel EQ window when you play or record the project, after setting the
desired EQ parameters. This will free up CPU resources for other tasks.
DJ EQ
The DJ EQ combines high and low shelving filters, each with a fixed frequency, and one
parametric EQ with an adjustable Frequency, Gain, and Q-Factor. A special feature of
the DJ EQ is that it allows the gain of the filters to be reduced by up to –30 dB.
DJ EQ Parameters
 High Shelf field and slider: Sets the amount of gain for the high shelving filter.
 Frequency field and slider: Sets the center frequency of the parametric EQ.
 Q-Factor field and slider: Sets the range (bandwidth) of the parametric EQ.
 Gain field and slider: Sets the amount of gain for the parametric EQ.
 Low Shelf field and slider: Sets the amount of gain for the low shelving filter.
