AkReal32 AkSpatialAudioInitSettings::fSmoothingConstantMs

[Experimental] Enable parameter smoothing on the diffraction paths output from the Acoustics Engine. Set fSmoothingConstantMs to a value greater than 0 to define the time constant (in milliseconds) for parameter smoothing. The time constant of an exponential moving average is the amount of time for the smoothed response of a unit step function to reach 1 - 1/e ~= 63.2% of the original signal. A large value (eg. 500-1000 ms) results in less variance but introduces lag, which is a good choice when using conservative values for uNumberOfPrimaryRays (eg. 5-10), uMaxDiffractionPaths (eg. 1-3) or fMovementThreshold ( > 1m ), in order to reduce overall CPU cost. A small value (eg. 10-100 ms) results in greater accuracy and faster convergence of rendering parameters. Set to 0 to disable path smoothing.
