Control Inputs
Frequency
1-5
Type Default Value
float32 1.0
Description: This control specifies frequency in Hertz. For the
BandPass, BandPassUnityGain, and PeakingEQ filters this control
specifies the center frequency of the passband. For the Notch filter
this control specifies the center frequency of the stopband. For the
LowPass and HighPass filters this control specifies the corner (-3
dB) frequency. For the LowShelf and HighShelf filters this control
specifies the midpoint frequency. The range of this control is [20,
24000).
Modifier: Multiply
Modifier_default: 500
Gain_dB1
-5
Type Default Value
float32 0.0
Description: This control specifies a gain value in dB. For Peak-
ingEQ, HighShelf, and LowShelf filters this control specifies the
gain applied to the passband. The range of this control is [-50,50].
Modifier: Plus
Modifier_default: 0.0
OutGain_
1-5
Type Default Value
float32 0.0
Description: This control specifies gain in a linear scale. For all
filters this control specifies the gain applied to the post-filtered
signal. This control takes effect even if Enable results in False and if
FilterType is ‘Off’. The range of this control is [0, 316.2277] and a
setting of 1.0 corresponds to a gain of 0 dB.
Modifier: Multiply
Modifier_default: 1.0
Control Inputs
QFactor1-
5
Type Default Value
float32 1.0
Description: The filter quality factor. This control specifies the
bandwidth for BandPass, BandPassUnityGain, Notch, and Peak-
ingEQ filters; the higher this value, the smaller the bandwidth. The
StartBand and EndBand variables adjust according to the QFactor
and are not adjustable in the display. For HighPass, LowPass, High-
Shelf, and LowShelf filters this control specifies the roll-off / corner
frequency gain; the higher this value the steeper the roll-off and the
higher the gain at the corner frequency. The range of this control is
(0, 16) and setting this control to a value of 0 or lower results in the
control defaulting to 0.707107.
Modifier: Multiply
Modifier_default: 0.7071.
Audio Outputs
OutSignal
Type Default Value
audio n/a
Description: The signal after it is filtered.
