Dual Tone Multi-Frequency Class.

Public Properties

Method	Description
ComputeFrequencies ( DTMF tone, long sampleIndex, int sampleRate ) : double	Computes a dual-tone multi-frequency sound for the given DTMF information and time. This method computes an amplitude representing the acoustic pressure of a DTMF of the given frequency for the given time.
DTMF ( ) : System	Constructs a new DTMF.
DTMF ( double lowFrequency, double highFrequency, double duration ) : System	Constructs a new DTMF using specified parameters.
Generate ( WaveFile destination, DTMF tone, double volume ) : void	Generates the specified dual-tone multi-frequency storing it in the specified WaveFile.
Generate ( WaveFile destination, DTMF tone, double volume, int repeatCount ) : void	Generates the specified dual-tone multi-frequency repeatCount times storing it in the specified WaveFile.
