SYNOPSIS

-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 the results in plain english. This is the default.

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

Output the results as a C source code snippet.
