LogicCompareConstReplaceInt32

Overview

Compares input with a user definable value with option to replace the output

Discussion

This module implements a general purpose logical compare module against stored user defined integer values that is capable of realizing many different logic operations. The behavior of the logic compare is controlled by the compareType parameter. compareType is an integer in the range from 0 to 5 inclusive.

The following table discusses the various compare oprations types and which variables are active in each case:

compareType = 0, performs logic equal operation.

compareType = 1, performs logic not equal operation.

compareType = 2, performs logic less than operation.

compareType = 3, performs logic less than equal operation.

compareType = 4, performs logic greater than operation.

compareType = 5, performs logic greater than equal operation.

If logic condition is true: replace output by user definable value (replacementValue).

If logic condition is false: copy value from input to output.

Module works on multichannel control signals, with individual parameters for each channel. No smoothing is applied when switching the output to or from the replacementValue.

Type Definition

typedef struct _ModuleLogicCompareConstReplaceInt32
{
ModuleInstanceDescriptor instance;            // Common Audio Weaver module instance structure
INT32 numChan;                                // Number of channels.
INT32* compareType;                           // Selects the type of comparison that is implemented by the module: Equal=0 NotEqual=1 LessThan=2 LessOrEqual=3 GreaterThan=4 GreaterOrEqual=5. One row per comparison.
INT32* constValue;                            // Selects value against to compare against.
INT32* replaceValue;                          // Selects value for replacement.
