EC_init
Description
Initializes the AEC algorithm.
Include
ec_api.h
Prototype
int EC_init(int* ptrStateX, int* xScratchMem, int order);
Arguments
ptrStateX
xScratchMem
order
Return Value
EC_OK
EC_ORDERERROR
a pointer to the state memory for this instance of AEC
a pointer to an area of scratch memory in X RAM used by
the AEC algorithm
an integer representing the filter order ( EC_ORDER )
If the value of EC_ORDER is correct
If the value of EC_ORDER is incorrect
Remarks
The value of order can be set to EC_ORDER , which is a macro in ec_api.h that
calculates the filter order based on the echo tail length required.
Code Example
int ecStateMemX [EC_XSTATE_MEM_SIZE_INT]
int ecScratchX [EC_XSCRATCH_MEM_SIZE_INT]
int ecScratchY [EC_YSCRATCH_MEM_SIZE_INT]
.
.
.
EC_init(ecStateMemX, ecScratchX, EC_ORDER);
