       tonetrain - Analyse telephony signal tones for the libvpb programmable detector


       tonetrain [options] file


       The  tonetrain  utility  analyses  a  recorded signal from file to determine the best tone
       detector parameters for recognising it.


       The following options are available:

       -V     Be more verbose during execution.

   Input options
       -w     Use wav file format for input.  This is the default.

       -v     Use vox file format for input.

       -s sec Skip the first sec seconds of the recording.  Useful if the  tone  does  not  begin
              cleanly at the start of the recording.

       -t sec Train  using  sec  seconds  of  the  recording.   Useful  if  only a portion of the
              recording actually contains the desired to to train for.

   Output options
       -p     Output the results in plain english.  This is the default.

       -e     Output the results in a form suitable for use with the VPB_TONE enviroment variable
              for libvpb.

       -c     Output the results as a C source code snippet.
