Remarks

ULoudnessNRT

ULoudnessNRT calculates the temporal evolution of perceptual loudness for a given sound. Loudness is available for individual channels or the overall sound asset. Normalized loudness values convert the range to 0.0 to 1.0 where 0.0 is the noise floor and 1.0 is the maximum loudness of the particular sound.
