# XDspProcessType

XDSP process type.

## Syntax

```cpp theme={null}
enum class XDspProcessType  : uint32_t  
{  
    None = 0,  
    Convolution = 1,  
    ForwardFourierTransform = 2,  
    InverseFourierTransform = 3,  
}  
```

## Constants

| Constant                | Description                                       |
| ----------------------- | ------------------------------------------------- |
| None                    | Invalid processing type.                          |
| Convolution             | Convolution of a signal with an impulse response. |
| ForwardFourierTransform | Forward Fast Fourier Transform.                   |
| InverseFourierTransform | Inverse Fast Fourier Transform.                   |
