tonegen − Test the Voicetronix programmable tone generator
tonegen [options]
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.
