dtmfcheck - Scan a wav file for DTMF tones
dtmfcheck [ --block size ] file
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.
The following options are available:
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.
