Spectral Clip - Native Instruments Razor Manual

▪ 3D: Sets the partial display into 3D mode. Hidden tricks: left click and drag on the dis­
play sets the perspective, right click and drag sets the amount of decay. Caution: The
3D mode is CPU intensive. Reaktor's CPU display doesn't reflect this cause 3D drains
the graphic thread. In case the graphic interface (like knob movement) gets less re­
sponsive it is recommended to turn 3D off. Also during music production where you
normally don't need 'Eye-Candy' it is recommended to turn 3D off to save CPU for more
important tasks. Also for sound design it is recommended to turn 3D off as it makes it
more difficult to see what happens to the partials when parameters are changed.
The impact of the 'dissonance' effects can be seen in 'partial' style displays. 'Dissonance' ef­
fects alter the frequency of the partials, so the position of the partials along the frequency axis
in the display gets altered too.

Spectral Clip

'Spectral Clip' limits loud spectral peaks in the output signal of the filter stage. It has a
spectral curve similar to a lowpass filter that acts as an upper limit to the partial ampli­
tudes. When you turn on 'Clip' in the display you will see a line that shows where the parti­
als are being stopped. This line is red if 'Spectral Clip' is on and grey if it is off. There is
no clipping artifact or extra harmonics created. This is very useful for limiting resonance
but can also be creatively used to color the voice like a lowpass filter.
Fig. 5.7 Spectral Clip.
▪ CLIP: Overall threshold level (dB) of the clipper curve.
PITCH CUT: Cutoff frequency (semitones) of the clipper curve. It automatically follows the
▪
global pitch.
▪ SLOPE: Slope (dB/Oct) of the curve after the cutoff frequency.
Often a resonant filter with lots of boost will get too 'boomy' when its resonant frequency gets
close to the fundamental frequency of the oscillator while sounding great otherwise. Spectral
Clip helps in this case: Set SLOPE to zero and set the CLIP LVL to a point where the boost in
this band gets enough limiting.
