# XDspActivationOptions

XDSP activation options.

## Syntax

```cpp theme={null}
enum class XDspActivationOptions  : uint32_t  
{  
    None = 0,  
    Deinterleaved = 2,  
    EnablePolarFormat = 4,  
    StereoImpulseResponse = 8,  
}  
```

## Constants

| Constant              | Description                                                                                                                                                                                                                                                                                                                                                                                              |
| --------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| None                  | No options are set.                                                                                                                                                                                                                                                                                                                                                                                      |
| Deinterleaved         | When set, the input data provided must be deinterleaved. Output data will be deinterleaved. This should only be used if [XDspActivationParameters::channelCount](/reference/audio/xdspaudio/structs/xdspactivationparameters) is equal to 2.                                                                                                                                                             |
| EnablePolarFormat     | Enable frequency domain polar format for [XDspProcessType::ForwardFourierTransform](/reference/audio/xdspaudio/enums/xdspprocesstype) output or [XDspProcessType::InverseFourierTransform](/reference/audio/xdspaudio/enums/xdspprocesstype) input. Default is **Cartesian** format. This flag should not be used with [XDspProcessType::Convolution](/reference/audio/xdspaudio/enums/xdspprocesstype). |
| StereoImpulseResponse | Treat the impulse response as stereo deinterleaved data. This should be only used if [XDspActivationParameters::channelCount](/reference/audio/xdspaudio/structs/xdspactivationparameters) is equal to 2, otherwise the impulse response will be treated as mono. If this is not set and the channel count is 2, the mono impulse response will be applied to both the channels.                         |
