+DSP
312
• Category: Math
• Channels: 0
Description:
Constant generates a constant DC signal with the value specified by
Constant
. This is useful for
generating a constant signal to be used as a control signal to be used as an input for other processing
blocks such as
MIO Channel Multiplier , NC SVF , Max , Min and Select .
Parameters:
Constant
[-100, 100]
The value of the output signal.
Divide
• Synopsis: Math operation to divide one signal by another
• Category: Math
• Channels: 2
Description:
Divide generates the signal (x ÷ y) from the input signals x and y. Mathematically, this would be ∞ when
y=0, but in general that will cause numerical stability problems in the processing graph, so the output
is limited to a very large, but not infinite value in the case that y=0. In general, this will be most useful
when y is a control signal with a non-zero value.
Please note that Divide is a relatively expensive operation, and should be avoided if possible (for
example, if you want to scale input signal X by a constant value, you are much better off multiplying
by the reciprocal of the scale factor).
Square Root
• Synopsis: Computes the Square Root of the input signal
• Category: Math
• Channels: 1
Description:
Square Root generates an output signal that is the Square Root of the input signal on a sample by
sample basis. Since +DSP does not support processing imaginary numbers, the output of Square Root
is flushed to zero if the input value is
Reciprocal Square Root
• Synopsis: Computes the 1/(Square Root of the input signal)
• Category: Building Blocks
• Channels: 1
Description:
Reciprocal Square Root generates an output signal that is the inverse of the Square Root of the input
signal on a sample by sample basis. Since +DSP does not support processing imaginary numbers, the
output of Reciprocal Square Root is flushed to a large, but not infinite number if the input value is
ADSR
