Since there isn't a users manual for Span, (at least I can't find one) what are some of the hidden features in Span that would benefit the user. I read somewhere that you can hae the sound of a instument occupying a particular frequency by clicking on the frequency and holding control, is this correct.
Should there be a documented goodies list for the wonderful hidden features. I need help with using this product.
Just a list of "How to -Tips and Tricks" would suffice if a manual is too much trouble.
I found this in the README file that came with SPAN:
SPAN is a real-time FFT spectrum analyzer PC VST plug-in. For the most part it
was derived from GlissEQ and CurveEQ professional equalizers and it reproduces
their spectrum analysis functionality.
Block - specifies the block size of the FFT (Fast Fourier Transform)
spectrum analyzer. The more the block size the more the resolution
in the lower frequency range, but less time coherence in the
higher frequency end.
Speed - specifies the speed (averaging coefficient) of the spectrum
analyzer. The less the speed the more latent spectrum analyzer is.
This setting is effective only if the "RealT" monitoring mode is
Slope - allows you to adjust the spectrum analyzer display slope towards
higher frequencies. This can be useful because higher frequencies
are usually weaker than lower frequencies, and thus tuning them
can be a difficult task. By choosing an appropriate slope setting,
you can compensate for this behavior and make the spectrum plot
more convenient and meaningful.
Channel - specifies which audio channel gets analyzed. "Avg" means the
average of the L and R channels will be analyzed. "Max" means
the maximum of the L and R channels will be analyzed.
Monitor - specifies the monitoring mode. "RealT" means real-time
spectrum is displayed. "Avg" means "average of all time" is
displayed. "Max" means "maximum of all time" is displayed.
In the "Inertia" mode the previously displayed spectrum will
be displayed again in a darker color.
In the "Full" display mode the whole spectrum resolution is
used. Other options offer graph displays of varying resolution.
Meter Mode - selects metering mode (the way RMS values represented).
Pure - standard RMS/PeakRMS value
Pure3 - standard RMS/PeakRMS value + 3 dB
K-20/K-14/K-12 - Katz metering system RMS/PeakRMS value
Low Freq/High Freq - frequency range to display.
dB Scale - specifies dB range to display. First value is dB shift and
the second value is dB range.
Peak Hold - amount of seconds to keep peaks displayed.
You can click the analyzer surface with the left mouse button to reset
By holding the CTRL key and dragging the control surface with the left
mouse button you can enable the bandpass sweeping mode.
Click any of the statistics counters to reset all counters. Please note
that RMS counters show dB values: A/B, where B = A + 3 dB. PRMS (peak RMS)
counter has 50 ms averaging time.
Here's a tip or trick - when remastering a track I set the Peak Hold to infinite and the Speed to 2 or 1 (very slow). That way I can see the difference between the peaks and average across the frequency spectrum. That helps me determin my general slope (via average curve) and overall dynamic curve across the freq spectrum. Comparing my song against certain favorite commercial references is pretty interesting and help me contour my EQ and Dynamics accordingly.
