WindowCustom

Overview

This module applies a user defined window function to the input.

Discussion

This module applies a user defined window to the input. The input and output pin must have the same attributes. There is a "blocksize" argument that defines the input block size and the window size. This module will operate only on non-complex float samples.

Type Definition

CODE

typedef struct _ModuleWindowCustom
{
    ModuleInstanceDescriptor instance;            // Common Audio Weaver module instance structure
    FLOAT32 amp;                                  // The peak level of the window
    FLOAT32* window;                              // Window coefficients
} ModuleWindowCustomClass;
