Allpass - Native Instruments Absynth 5 Reference Manual

Main Panel
The highpass filters in ABSYNTH 5 contain the following parameters on their Main panel:
•
Frequency control and Frequency menu: The Frequency control allows you to set the cut-
off frequency in semitones (Trans) or in Hertz (Hz), upon the selection in the nearby
Frequency menu.
•
Resonance control (HPF -12dB only): Sets the resonance at the cutoff frequency.

5.5.6 Allpass

Allpass filter Allpass 4
Allpass filters allow all frequencies to pass through the output with similar strength, but modify
the phase of the signal. Allpass filters are useful for creative filtering as they can easily produce
phasing or resonating effects. With allpass filters, the number of poles define the number of
peaks in the frequency spectrum of the filtered signal. With high resonance values, an 8-pole
allpass filter can sound very similar to a bell.
The following allpass filters are available in the Type menu:
•
Allpass 2: 2-pole allpass filter.
•
Allpass 4: 4-pole allpass filter.
•
Allpass 8: 8-pole allpass filter.
Main Panel
Every allpass variant shares the following two parameters on the Main panel:
•
Frequency control and Frequency menu: The Frequency control allows you to set the cut-
off frequency in semitones (Trans) or in Hertz (Hz), upon the selection in the nearby
Frequency menu.
•
Resonance control: Sets the resonance.
