Mode

Which value to output from the accumulated values:

  • Average: will compute and return the average of all accumulated values;
  • Sum: will compute and return the sum of all accumulated values;
  • Oldest: will always return the oldest value in the accumulator.
Accu Size Number of values to accumulate in the accumulator.
For instance, a value of 1 means it only contains the current input value, while a value of 2 means it contains the current input value and the input value at the previous frame.
If a second Channel Operator node is connected to this node as an input, this attribute gets overwritten by its output value.
First In First Out If checked, when a new value is added and the number of values equal the Accu Size, oldest value is discarded. Else newest.
If a third Channel Operator node is connected to this node as an input, this attribute gets overwritten by its output value.
Enable Accu If checked, new values are added to the Accu node at each compute.
If a fourth Channel Operator node is connected to this node as an input, this attribute gets overwritten by its output value.
