Kn0ck0ut takes two mono 44.1KHz inputs and spectrally subtracts one from the other. It can be used to help create 'acapellas' - to extract vocals from a track - if an instrumental version (or section) of the track is available.... [more]

Sp3ctr3 is an FFT-based audio-mangling effect plug-in. Sp3ctr3 includes the following controls: Lo cut - hard cut of lo frequencies. Hi cut - hard cut of hi frequencies. Blur - spectral blur - basically, degradation and noise. Hold - keeps spectral peaks - like reverb on acid but not. Harmonic - 0>0.5 removes integer harmonics of the detected fundamental 0.5>1 removes everything else. Threshold - cuts low amplitude partials. Edges - 0>0.5 removes slow-changing partials (long pure notes) 0.5>1 removes fast-changing partials (hard attack). Warp - warps the frequency spectrum... [more]
