Discussion

DC Blocking filter. The module supports multi-channel

Type Definition

typedef struct _ModuleDcBlock
{
    ModuleInstanceDescriptor instance;            // Common Audio Weaver module instance structure
    FLOAT32 fc;                                   // Cut on freq for highpass filter
    FLOAT32 coeff;                                // coefficents for dc blocking filter.
    FLOAT32* filterStates;                        // State variable, 1 per channel
} ModuleDcBlockClass;
