.SH NAME
dtmfcheck \- Scan a wav file for DTMF tones
.SH SYNOPSIS
.BR dtmfcheck " ["
.BI \-\-block " size"
.RI ] " file"
.SH DESCRIPTION
The \fBdtmfcheck\fP 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.
.PP
In the latter case the \fB\-\-block\fP option may be useful to zero in on the
precise point in the file where the troublesome audio occurs.

.SH OPTIONS
The following options are available:
.TP
.BR \-\-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.
