112MainStage Effects
As soon as the Analyzer is activated, you can change the scaling from the default dynamic
range of 60dB. Drag vertically on the scale to the right of the graphic display to set
the maximum value to anywhere between +20dB and −80dB. The Analyzer display is
alwaysdB-linear. There are several additional Analyzer parameters in the Channel EQ
shortcut menus and the extended parameters.
Note: High Analyzer resolutions require significantly more processing power. High
resolution is necessary when attempting to accurately analyze very low bass frequencies,
for example. It is recommended that you turn off the Analyzer after setting EQparameters.
Linear PhaseEQ
MainStage Linear PhaseEQ overview
The high-quality Linear PhaseEQ effect is similar to Channel EQ, sharing the same
parameters and eight-band layout. See MainStage Channel EQ overview. You can copy
settings between them. If you replace Channel EQ with Linear PhaseEQ (or vice versa) in
the same effect slot, the current settings are automatically transferred to the new EQ.
Linear PhaseEQ uses a different underlying technology to Channel EQ that preserves the
phase of the audio signal. Phase coherency is always maintained, even when you apply
extreme EQcurves to the sharpest signal transients. This differs from Channel EQ, which
can introduce phase shifts of the signal that can have an audible (and often desirable)
effect on the sound.
A further difference between Channel EQ and Linear Phase EQ is that the latter uses a
fixed amount of CPU resources, regardless of the number of active bands. Linear PhaseEQ
also introduces greater amounts of latency. See the Linear PhaseEQ use, parameter, and
Analyzer sections.
Note: Use the Linear Phase EQ where phase coherence between tracks is needed, such
as multi microphone recordings. The Linear Phase does not introduce any phase shift to
the signal which can also be beneficial in mastering, but it does impact on the onset of the
transient. This is most evident when using steep cut filters, or high boosts/cuts of narrow
filter bands.
