DampingInverseLogarithmic Method

Produces an inverse logarithmic damping curve - slowly damping with a sharp end from 1 to 0 over the samplePeriod.

Namespace: GSF.Media.Music
Assembly: GSF.Media (in GSF.Media.dll) Version: 2.4.218-beta
Syntax
public static double InverseLogarithmic(
	long sampleIndex,
	long samplePeriod,
	int sampleRate
)

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 damping would be similar to that of a note produced on an electronic keyboard or a breath based instrument.
