Pass Filter

  

Name	Description
Channel Count	Select from a list of default channel counts or set a custom amount (up to 32).
Filter Type	Low pass or High Pass can be selected.

 

The Pass Filter object is for High Pass and Low Pass filter types.  When this object is created from the Object Toolbar, a control dialog is presented.  Under Filter Type, choose whether Low Pass or High Pass is desired.

 

In the Low Pass filter control dialog, Filter Type selects from Butterworth, Linkwitz-Riley or Bessel.  

Filter Slope (dB/Oct) determines how quickly the filter’s amplitude response rolls off above the cutoff frequency.  

Cutoff Freq (Hz) specifies the point at which the filter’s amplitude response begins to roll off.  For the Butterworth and Bessel types, the cutoff frequency represents the -3dB point in the rolloff.  For the Linkwitz-Riley type, the cutoff frequency represents the -6dB point.

 

In the High Pass filter control dialog, Filter Type selects from Butterworth, Linkwitz-Riley or Bessel.  

Filter Slope (dB/Oct) determines how quickly the filter’s amplitude response rolls off below the cutoff frequency.  

Cutoff Freq (Hz) specifies the point at which the filter’s amplitude response begins to roll off.  For the Butterworth and Bessel types, the cutoff frequency represents the -3dB point in the rolloff.  For the Linkwitz-Riley type, the cutoff frequency represents the -6dB point.
