SYNOPSISaudial [-audio servername] [-volume 0-100] [-spacing milliseconds] [-pause milliseconds] [-duration milliseconds] dialstring
audial -recognize [-microphone] [-gain 0-100] [-time seconds]
DESCRIPTIONThe audial program generates touch tones suitable for dialing a North American telephone. audial can also recognize touch tones and produce the corresponding string.
GENERAL OPTIONSThe 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.
DIAL OPTIONSThe 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.
- -pause milliseconds
- 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.
DIALING STRINGThe following characters may be used in a dialing string:
- The corresponding touch tone is generated.
- 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.
- 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 is forever.
The following environment variables are used by audial:
- This specifies the name of default audio server to contact if no name is explicitly given on the command line.
- This specifies the name of an X Window System display that should be assumed to also have a corresponding Network Audio System server.
