SubbandControllerInit

Initializes the subband controller state structure.

Syntax

IppStatus ippsSubbandControllerInit_EC_32f(IppsSubbandControllerState_EC_32f* pState, int numSubbands, int frameSize, int numSegments, ippECFrequency sampleFreq);

IppStatus ippsSubbandControllerInit_EC_16s(IppsSubbandControllerState_EC_16s* pState, int numSubbands, int frameSize, int numSegments, ippECFrequency sampleFreq);

Parameters

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

Description

The functions ippsSubbandControllerInit_EC are declared in the ippsc.h file. These functions initialize the state structure and the internal data of the subband controller algorithm. The functions ippsSubbandControllerUpdate_EC and ippsSubbandController_EC use this memory in their operation.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when one of the specified pointers 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.
