Parameters

tone  DTMF
Instance of the DTMF specifying the duration as well as the low and high frequencies of the dual-tone.
sampleIndex  Int64
Sample index (represents time anywhere from zero to full length of tone).
sampleRate  Int32
Number of samples per second.

Return Value

Double
The amplitude for the dual-tone at the given time.
Remarks
This method computes an amplitude representing the acoustic pressure of a DTMF of the given frequency for the given time.
