Overview

Reads the data from a delay_state_writer_module with a given delay

Discussion

This module reads the data from a delay_state_writer module. The input is a single channel, single block, integer, which is the output from a delay_state_writer module. The output has the same number of channels, blocksize, and sample rate as the input to the delay_state_writer module. The currentDelay value is how much to delay the samples that are stored in the delay_state_writer module. This can be a non-integer value, in which case interpolation is applied to the samples. 2 types of interpolations are possible - linear or cubic. Limitations of this module is that it has to be on the same hierarchy as the delay state writer module and that it has to be directly connected to the delay_state_writer module with nothing (except markers) in between.

Type Definition

typedef struct _ModuleDelayReader
{
    ModuleInstanceDescriptor instance;            // Common Audio Weaver module instance structure
    INT32 maxDelay;                               // Max Delay of the writer module (per channel)
    FLOAT32 currentDelay;                         // Current delay
    INT32 interpolationType;                      // Interpolation type - linear, cubic, etc
    INT32 dswObjectID;                            // Object ID of the upstream DelayStateWriter module
    void * dswObjectPtr;                          // Points to the upstream DelayStateWriter module
} ModuleDelayReaderClass;
