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.
