NAME
       dtmfcheck - Scan a wav file for DTMF tones

SYNOPSIS
       dtmfcheck [ --block size ] file

DESCRIPTION
       The  dtmfcheck  utility	scans  for  valid DTMF in a test file.	It may be used to analyse recordings of audio where DTMF tones have either
       failed to be detected or have been improperly detected.

       In the latter case the --block option may be useful to zero in on the precise point in the file where the troublesome audio occurs.

OPTIONS
       The following options are available:

       --block size
	      Set the block size (in bytes) sent to the DTMF detector for processing.  The default (and maximum) value	is  32768  (2  seconds	of
	      audio), but smaller values may be given to more precisely locate where in a file a particular tone is detected.
