Normalizes the input signals to signals between 0 and Norm. Please specify the Range and Offset of the input and the Norm of the output



Use the Normalizer to shift and resize signals in such a way, that they become signals between 0 and a norm value. How much the signals are shifted and resized depends on the settings of the lowest and highest input values.

Operator ports

Input S: Floating point values

Output S_norm: Floating point values

Optional documentation of this object. If this object is an operator, the Documentation text is displayed below the operator symbol.

Special dialog to change properties of this object: Settings per channel

Allows to change the normalization settings for each channel that is currently connected at the input. For each channel, the output Norm and the input High and Low range can be specified. You may select multiple rows, to change a setting for all rows at once.

Variable Parameters

Find more information about Variable Parameters here: "Variable Parameters"

type: Real value
Highest value of the input range for all channels

type: Real value
Lowest value of the input range for all channels

type: Real value
Norm setting for all channels. The signals are normalized between 0 and Norm.


The Normalizer converts a signal such that it fits between 0 and another value (the norm). The next image illustrates this:

In this example, the original signal has a range between -250 and 250. After the Normalizer, the range is between 0 and 1. For this example, the settings for this channel in the Normalizer are:

Norm = 1
High = 250
Low = -250

If the input signal's amplitude extends beyond the High and Low settings of the Normalizer, then the signal is truncated. In that case you will see flat tops. So, the output will never stretch beyond the Norm value.

The calculation is also performed on constant values (e.g. from a Constant ("K")).
