Highshelf Filter Node

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

Inputs #

AudioThe Audio line to which the filter is applied.
Frequency-controlA 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-controlA 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.

Settings #

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

Outputs #

AudioThe filtered audio stream.

Audio and Control lines (visualized with blue and purple, 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 (purple), or vice-versa.

Technical details #

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