Spectral Signature is a dynamic filter tool to even out differences
between signals of different source or condition. It does not have an
absolute reference. Only if the incoming signals frequency response
equals the reference response (signature), will Spectral Signature
operate in a neutral manner. To create a reference spectrum, which is
called 'Signature', start your reference signal and hit the 'Learn' button.
After a couple of seconds (see below), the Signature is updated. If the
input signal does not change, the upper graph shows that the input and
output curves are alike. If the incoming signal spectrum changes,
Spectral Signature starts to even out the tonal differences, without
destroying the original structure.
[manual / 1s ... 30s / 1min]
Determines the time over which the input frequency response is
integrated to create the signature. A shorter time is sufficient for single
channel signals, where the content remains stable over time (for
example a presenter microphone). Longer time settings are appropriate
for mixed content or buses (for example a studio output).
[ON / OFF]
The color code of the column headers will change depending on the
program selected for gain change (upper) display.
White color represents the selected program while pink represents the
second program. If you select program 2 for example it becomes white
while Program 1 becomes green:
[Linked / Unlinked] for program 2
I.e. for non stereo operation you may unlink the function and a 3
is introduced because we have now 3 independent Spectral Signature
processes running:
