Kn0ck0ut is a
free VST plugin (Win and Linux) that takes two mono
inputs and spectrally subtracts one from the other.
It can also retrieve centre-panned material from
released under the terms of the GPL version 3 (with
the permission of st3pan0va).
In addition to
the features of the original Kn0ck0ut, Kn0ck0ut-LV2
- Improved performance
through use of FFTW and more efficient buffering
- Completely variable FFT
size and overlap amount controls.
- Experimental "Phase
Compensation" option, which will perhaps
preserve additional fidelity in certain cases.
- Restored Low-cut filter
which was removed in later releases.
