Overview
Sets filter coefficients in other modules
Discussion
The Coeff Table module, also called the Param Set Table module, writes the values of one column of a statically defined table to an internal array of another module. A common use case is to update the coefficients of an FIR module based on changing conditions in the system.
...
See the Param Set module documentation for more detail on how to specify the target module's array, and the meaning of each setBehavior type.
Type Definition

typedef struct _ModuleCoeffTable
{
ModuleInstanceDescriptor instance; // Common Audio Weaver module instance structure
INT32 index; // current index to coeff table
INT32 numRows; // the size of each vector
INT32 numCols; // the number of vectors
INT32 setBehavior; // Controls the behavior of the module
FLOAT32* coeff; // 2-D coeff table.
void * modPtr; // Points to the module to set
void * varPtr; // Points to the variable to set within the module instance structure
