The Squash, Trash, and Postfilter modules in Trash are "multiband" and
allow you to apply processing independently to up to four frequency ranges.
The ranges (or cutoffs) of these four bands are shown at the top of the multiband modules with the three vertical lines. You can adjust the cutoffs by dragging the cutoff lines to the left or right with the mouse.
Note that the same four bands apply to all multiband modules. The cutoff frequencies can be adjusted from any of the multiband module screens, and the new cutoffs will apply to the other multiband modules.
Bypass a Band
You
can bypass the processing for a specific band (or bands) by clicking on
the box labeled "B" in the upper left corner of the band. This
allows you to hear the audio within that band, but without any
processing for that band.
Mute a Band
You can
mute a band by clicking on the box labeled "M" in the lower left corner
of the band. This allows you to adjust multiband processing by hearing only
the audio within the non-muted bands.
Solo a Band
You can solo a band by holding down the
Alt key and clicking the box labeled "M" in the lower left
corner of the band.
Change the Number of Bands
You can choose to split the audio
into 1,
2, 3
or 4 bands. To add or remove bands, right-click (under OS X you
can also ctrl-click) on the mini-spectrum and select "Insert Band" or "Remove
Band" as shown below:
Copy and Paste Settings Across
Bands
Using the same right-click (under
OS X you can also ctrl-click) menu, you can copy settings
from one band and apply them (paste them) to another band. This is helpful,
for example, for duplicating settings across bands in the multiband squash
module.
Adjusting Controls in Other Bands
When you select a control, horizontal lines appear on the multibands. These lines allow you to adjust the control that you've selected for other bands, without having to switch to that band. So for example, in the screen below, the lower band is the selected band, and the input gain control is selected. You can adjust the input gain control for the middle band as shown by simply dragging the horizontal line in the middle band.
Note: This help file is a quick reference for basic Trash functions and controls. We have separate "how to" guides that provide tips and techniques for getting the most out of Trash. You can download these guides from http://www.izotope.com/products/audio/trash/guides.html
