NAME

       tonegen - Test the Voicetronix programmable tone generator

SYNOPSIS

       tonegen [options]

DESCRIPTION

       The tonegen utility uses the programmable tone generator to send tones to some port.

OPTIONS

       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.
