SubbandControllerDTInit

Initializes the subband DT controller state structure.

Syntax

IppStatus ippsSubbandControllerDTInit_EC_16s(IppsSubbandControllerDTState_EC_16s* pState, int numSubbands, int frameSize, int numSegments, ippPMCFrequency sampleFreq);

Parameters

pState	Pointer to the subband controller DT state structure to be created.
numSubbands	Number of subbands.
frameSize	Size of the frame.
numSegments	Number of segments.
sampleFreq	Sample frequency.

Description

The functions ippsSubbandControllerDTInit_EC are declared in the ippsc.h file.

This function initializes the state structure and the internal data of the subband DT controller algorithm. The size of the required memory must be computed using the function beforehandippsSubbandControllerDTGetSize_EC.

This state structure is used by the functions ippsSubbandControllerDT_EC and ippsSubbandControllerDTUpdate_EC.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when the pointer pState is NULL.
ippStsBadArgErr	Indicates an error when numSubbands is less than or equal to 0, or numSegments is less than or equal to 0, or frameSize is less than or equal to 0.
