Highshelf Filter Node

Standard highshelf filter. Frequencies higher than a specified frequency get a boost or an attenuation; frequencies lower than it are unchanged.


Audio The Audio line to which the filter is applied.
Frequency-control A Control input to automate the Frequency setting, in Hz, from 10 Hz to the Nyquist frequency. This input can be toggled from the Node settings panel.
Gain-control A Control input to automate the Gain setting, in dB, from -40 dB to 40 dB. This input can be toggled from the Node settings panel.


Frequency Sets the lower limit of the frequencies getting a boost or an attenuation.
Gain The boost, in dB, to be applied; if negative, it will be an attenuation.
Filter order Represents the order of the differential equation describing the filter. In other words, this essentially sets how many times the filter is applied.


Audio The filtered audio stream.

Audio and Control lines (visualized with blue and orange, respectively) are both analogous to an analog signal. They can be used interchangeably, and, for example, an Audio output (blue) can be connected to a Control input (orange), or vice-versa.

Technical details

This Node has exactly 2 samples of latency (equals ~0.0045 milliseconds at 44.1 kHz).
