The absolute gate threshold can be set individually for every single
band. However, in most cases this is not necessary. Checking this box
links all gate thresholds together. This connection is absolute,
differences between bands will be overwritten. Please note: For
convenient operation, this function is also available
(in the Expert section, see below) within the web interface.
It may show the reference curve for all programs by a color code.
Above we see an additional pink line that represents Program 2.
It may be disabled by the "Graph Permanently Visible" switch below the
graph display.
Spectral Signature does not work with an absolute level reference. Its
frequency response is based on level differences between bands only.
Thus a signature is only represented on a relative graph showing the
level positions related to the neighboring bands. In consequence,
having a straight line does not mean Spectral Signature is not doing
anything or is in a 'neutral' status. A straight line would cause Spectral
Signature to modify the input signal towards the frequency response of
white noise which is, in most cases, not desirable.
On mouse over you can read the actual setting of a particular
band (BAND 5 above).
To change a band, just grab and drag the corresponding sphere. It is
recommended to use the 'Learn' function first (see below). Every single
band can have an individual max gain value that limits the maximum
amplification and attenuation. To set this value, grab and drag the
smaller sphere on the bottom of the main sphere. The max gain setting
is indicated by the size of the main sphere. The lowest and highest
values are indicated by a flashing edge.
[ON / OFF]
Instead of dialing in all max gain settings individually per band, this link
function is a handy tool for basic setup. This connection is absolute,
differences between bands will be overwritten.
[ON / OFF]
Checkboxes on the bottom of the lower graph can be used to bypass
single bands from processing.
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 columns will change depending on the program
selected for gain change (upper) display.
