Class implements cache storage of fractional delay filter banks.

Member Function Documentation

getFilterBank()

static CDSPFracDelayFilterBank & r8b::CDSPFracDelayFilterBankCache::getFilterBank ( const int  aFilterFracs, const int  aElementSize, const int  aInterpPoints, double  ReqAtten, const bool  IsThird, const bool  IsStatic  )

static

Function calculates or returns reference to a previously calculated (cached) fractional delay filter bank.

Parameters

aFilterFracs	The number of fractional delay positions to sample, -1 - use default.
aElementSize	The size of each filter's tap, in "double" values.
aInterpPoints	The number of points the interpolation is based on.
ReqAtten	Required filter attentuation.
IsThird	"True" if one-third filter is required.
IsStatic	"True" if a permanent static filter should be returned that is never removed from the cache until application terminates.

Returns

Reference to a filter bank.

getObjCount()

static int r8b::CDSPFracDelayFilterBankCache::getObjCount ( )

static

Returns

The number of filters present in the cache now. This value can be monitored for debugging "forgotten" filters.
