getFilterBank()

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

static

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.
