SumDiffFract32

Overview

Summer/Differencer

Discussion

This module has 2 input pins and 2 output pins. Input pins must have same block size, number of channels, and sample rate. Output pins have same block size, number of channels, and sample rate as input pins. Output1 = (Input1+Input2)/2 Output2 = (Input1-Input2)/2. Note that if we cascade 2 of these modules then outputs of 2nd module are equal to inputs of first module.
