PROGRAM:
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.
