(8.D.2.5) FractionalDelayV2Fract32
Overview
Provides fractional delay
Discussion
This subsystem implements a delay module which provides a fractional delay. This can be achieved by cacading the delay module and a fir filter which is designed to provide the fractional delay of 0.0to 1.0. Filter will have own set of coefficients for each fractional value which are calculated at design time.
Type Definition
typedef struct _ModuleFractionalDelayV2Fract32
{
ModuleInstanceDescriptor instance; // Common Audio Weaver module instance structure
INT32 maxDelay; // Maximum delay, in samples. The size of the delay buffer is maxDelay*numChannels.
FLOAT32 floatCurrentDelay; // total delay
awe_modDelayInstance *ConstantDelay; // Time delay in which the delay is specified in samples
awe_modFIRFract32Instance *FIRmodule; // FIR fract32 filter
} ModuleFractionalDelayV2Fract32Class;
