Parameters

sampleIndex  Int64
Sample index (0 to samplePeriod - 1).
samplePeriod  Int64
Total period, in whole samples per second (i.e., seconds of time * sampleRate), over which to perform damping.
sampleRate  Int32
Number of samples per second, if useful for calculation.

Return Value

Double
Scaling factor used to damp an amplitude at the given time.
Remarks
This is just used for an interesting note effect.
