Peak Meter and Clip Indicator
The wide meter bar to the left is a responsive peak meter
which allows you to observe the exact input level at any point
in time. A red clip light at the top of the meters indicates that
three consecutive samples are at maximum which is taken to
mean that the input is higher than 0dB FS and is therefore
clipping. It will stay illuminated for 1 second following clip
detection, after which it will automatically clear. It can also
be cleared at any point with a mouse click.
Dynamic History Meter
The thin white bracket on the far right of the meter gives an
indication of the recent dynamic range of a signal. The top of
the bracket measures the most recent peak level of the signal,
where as the bottom of the line shows the smallest peak to
have happened recently. If the bracket is long it indicates that
the signal has a large swing in dynamic range and if it is short
the range is small. If the top and bottom points of the bracket
are quickly moving around, it can be assumed that the
dynamic range is quickly changing, which could be
interpreted as an ‘energetic’ signal.
RMS Meter
The thinner bar to the right of this shows the RMS (average)
level. This is useful in graphically judging the ‘loudness’ of
the signal and when used in conjunction with the peak meter
can give a good idea of the peak to RMS ratio (crest factor) of
the signal.
5.5 FFT Spectrum Analyser
A real-time FFT analyser engine reports the amplitude of all
frequencies at any moment in time. As the analyser is placed
post-EQ, you can see what effect the processing has on the
frequency spectrum. The Spectrum Analyser makes it easy to
spot an offending frequency that needs attenuating, or a range
of frequencies that require boost.
The analyser graphic can be turned off and on with the
‘Analyse’ button.
5.6 Automation
Every X-EQ plug-in parameter can be automated as long as
parameter automation is supported by the host application.
The method for recording and editing automation varies from
host to host. For specific instructions on using automation
with your host, consult the host application’s documentation.
