The audial program generates
touch tones suitable for dialing a North American telephone. audial can
also recognize touch tones and produce the corresponding string.
The following options may be used in either dial or recognition
mode:
- -audio servername
- This option specifies the Network Audio System server
on which the files should be played.
The following options may
be used in dial mode:
- -volume 0-100
- This option specifies the volume at which
the data should be played as a percentage of the maximum possible volume.
The default is 100 percent.
- -spacing milliseconds
- This option specifies
the number of milliseconds to wait in between each digit. The default is
100.

- This option specifies the number of milliseconds
to wait whenever a comma (,) is used in a dial string. The default is 400.
- -duration milliseconds
- This option specifies the duration of each tone in
milliseconds. The default is 100.
The following characters
may be used in a dialing string:
- 0123456789*#
- The corresponding touch tone

- Tones representing the 4 "function" keys often found
on a keypad are generated.
- ,
- A blank tone whose length is specified by the
-pause option is generated.
Any other characters are ignored.
- -recognize
- Enables recognition mode. audial will attempt to recognize
touch tones from the input device and output the corresponding character.

- Use microphone gain levels on the audio input device. If a microphone
is plugged into the audio input jack, this option should be used.
- -gain 0-100
- This option specifies the input gain level. The default is 95.
- -time seconds
- This option specifies how long to attempt the recognition. The default
