CrossOver is a plugin to split an
incoming signal into several (at most 4) frequency
ranges. It can be used to build your own multiband
effects within a modular (sub)host environment. By
using only 2 bands, you can also create
bass-effects. These are effects which (counterintuitively)
keep the low frequency range dry and affect only the
high frequency range.
The band-splitting is done by
complementary pairs ofLinkwitz-Riley lowpass/highpass
filters, the slope of which is adjustable between 12
and 96 dB/oct. For configurations with more than 2
output bands, the signal is first split into 2 bands
(low and high) and then the low or high or both
bands is/are split further, thus the splitting is
done in a hierarchical manner.
CrossOver is available to download
as a freeware VST effect plug-in for Windows PC.
