XDspActivationOptions - XBOX Game Development Documentation

XDSP activation options.

Syntax

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 is equal to 2.
EnablePolarFormat	Enable frequency domain polar format for XDspProcessType::ForwardFourierTransform output or XDspProcessType::InverseFourierTransform input. Default is Cartesian format. This flag should not be used with XDspProcessType::Convolution.
StereoImpulseResponse	Treat the impulse response as stereo deinterleaved data. This should be only used if XDspActivationParameters::channelCount 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.
