Syntax

float CalculatePerceptualEnergy
(
    TArrayView< const float > InSampleView,
    const int32 InNumChannels,
    TArray< float > & OutChannelEnergies
)

Remarks

Calculate perceptual energy.

InSampleView InSampleView is expected to contain interleaved audio with (InSettings.FFTSize * InNumChannels) number of samples.

InNumChannels Number of input channels.

OutChannelEnergies Will be populated with energies on a per channel basis.

The overall perceptual energy is returned.
