ADOBE AUDITION 1.5
User Guide
To generate DTMF signals:
1
Place the cursor where you want to insert the signals. Or, if you want to replace part of
the existing waveform, select the desired range of audio data.
2
Choose Generate > DTMF Signals.
3
Set the following options as desired, and click OK:
Dial String
Specifies the phone number for which you want to generate tones. You can
also enter other characters, such as the asterisk (*) and pound (#) symbols, as well as the
letters “A,” “B,” “C,” and “D.” Entering the pause character (see “Pause Character” in this
list) inserts a pause of a defined length.
Tone Time
Specifies the milliseconds for which the tones will last. The standard time for
DTMF tones is 100 milliseconds.
Break Time
Specifies the number of milliseconds of silence between successive tones.
Pause Time
Specifies the length that is assigned to the pause character when it is used in
the Dial String text box.
Pause Character
Specifies which character Adobe Audition interprets as a pause.
DTMF Signals
Generates DTMF signals by using combinations of the frequencies 697 Hz,
770 Hz, 852 Hz, 941 Hz and 1209 Hz, 1336 Hz, 1477 Hz, and 1633Hz.
MF Signals (CCITT R1)
Generates MF signals (tones that are internal to telephone
networks) using paired combinations of the frequencies 700 Hz, 900 Hz, 1100 Hz, 1300 Hz,
1500 Hz, and 1700 Hz.
Custom
Specifies the combinations of frequencies to be used in generating signals. Select
this option, and then enter values in the Hz text boxes of the keypad.
Amplitude
Determines the volume level (as a percentage) of the tones generated, where
100% means maximum volume without clipping.
Twist
Specifies how much louder the higher frequency tone is from the lower frequency
tone. Enter a value (in decibels) in the Twist text box to increase the volume of the higher
frequency tone accordingly.
Reset To DTMF
Clears any custom frequency entries and replaces them with the standard
DTMF frequency combinations.
