tonegen - Test the Voicetronix programmable tone generator
The tonegen utility uses the programmable tone generator to
send tones to some port.
The following options are available:
- --card number
- Explicitly select the card to test. Default is card 0.
- --port number
- Explicitly select the port to test. Default is port 0 of the card being
tested.
- --toneid
num
- Play a locale specific predefined tone, where 0 <= num <
VPB_TONE_ID_MAX. The locale is decided according to the value of the
VPB_COUNTRY environment variable.
- --tone n freq
mag
- Set a single component for a user defined tone. This option may be used
more than once with different values of n to set the components of a
multi-frequency tone. Legal values for the other parameters are 0 <
freq <= 4000 (Hz), and -inf < mag < 0.0 (dB).
- --ontime
ms
- The number of milliseconds that a user defined tone should be on for.
- --offtime
ms
- The number of milliseconds that a user defined tone should be off
for.
- --dial digits
- Generates a dial string using the specified dtmf digits.
- --sync
- Play tones using the synchronous api functions. The default is to use the
async api.
- --loop
- Loop cadenced tones continuously. Has no effect if a continuous tone has
been specified.
- --recgain
db
- Set software record gain in dB. Default is 0.0
- --rec file
- Record audio to a file while playing.
- --contest
- Do not wait for a tone to complete before starting the next one. This can
be useful for stress testing the coherency of the tone generator.
- --help, -?
- Show summary of these options.
