189 Chapter 9: Generate Menu - Edit View T he Generate menu displays all the options that relate to waveform generation when you're in the Edit View mode. Silence This function generates a specified amount of silence (entered in seconds) from the current playbar cursor position. Any following audio is pushed back in time, thereby lengthening the waveform's duration. Silence will replace any selected area. To use, just enter the desired amount of silence you wish to generate (measured in seconds) and press the OK button. Feel free to use decimals for partial seconds. For instance, entering .3 in the Silence Time field will generate exactly threetenths of a second of silence. To "silence out" a highlighted selection, use Effects > Silence instead. DTMF Signals This function generates Dual Tone Multi-Frequency (DTMF) signals (a.k.a. "touch tones") used for dialing telephone numbers over phone lines that are capable of responding to touch tone signals. These signals are recommended internationally by the International Telegraph and Telephone Consultative Committee as the signals for pushbutton telephones. Generate DTMF Signals dialog Keep in mind that the DTMF signals generated by telephone pushbutton keypads are different from the Multi-Frequency (MF) tones generated by the telephone network to transmit information. Adobe Audition's DTMF Signals function can generate MF tones as well.
