- Capturing audio with a modem
- Posted by Joshua Beall on December 23rd, 2003
Hi All,
I am interested in capturing audio data from a phone line with my modem.
Can anyone recommend a program that can do this? Preferably free, or at
least with a free trial version.
I am running XP Pro, and device manager lists my modem as a "SoftK56 Data
Fax CARP", and the manufacturer is "CXT".
Any ideas? Is this even feasible with my modem?
Sincerely,
-Josh

I take it you want to record your phone conversations? Call Station and
Advanced Call Center come to mind. HTH

Does your modem have a connector that can go to a sound card (i.e., it
will let you hear the dial tones and handshaking through your speakers)?
If so, check if your sound card has an option to record "What U Hear".
It probably won't have a record input for the modem specifically but it
should be able to record whatever gets played on the speakers through
the sound card. Then add the M2 command to the AT dialing or
initialization sequence in the properties for your modem (to keep the
modem speaker on).
I take you want to hear to show someone else what the modem sounds like
while you are transferring data through it.

There isn't anything special about recording from the modem... it's a
device in the audio mixer (maybe hidden, check your mixer settings).
If your modem is a soft/winmodem it may transmit audio over PCI bus,
or otherwise (and more common on older modems) is to have an internal
analog cable going from the modem to the soundcard (or motherboard)
"TAD" (or of course it could be labeled "modem") audio socket, which
is often green-colored.
On even older modems you might have only external 'phone jacks, in
which case you'd need a phone-plug jumper cable to the audio-in on the
soundcard or motherboard.
So yes, it's feasible but the modem has to support voice and you may
need a connector, but they're generic/standard connectors, not hard to
come by. It will be lower-fidelity mono sound, at whatever rate the
modem supports, though that doesn't limit the sound card's sampling
rate, just that there's no point recording it in stereo to use twice
the bitrate for two duplicate channels.

Planning on listening in on phone calls!?

How do I find this out? I checked my mixer settings and there is a slider
for "phone line" but not "modem".
I am thinking probably yes, since the first part of the name is "Soft56k".
Unfortunately I failed to specify a rather important detail in my original
post: this machine is a laptop, so I cannot really open it up and check for
connectors from the modem to sound card. Everything is integrated.
What is a "phone-plug jumper cable to the audio-in"? Is this a cable with
RJ-11 on one end and a 1/8" miniplug on the other? If so, I had no idea you
could do something like that!
I will try all the different suggestions that I have gotten here, and report
back on my success/failure. Actually, I will probably report back with more
questions. Thanks for the help!

Well, that would be nice, but what I want to do at the moment is archive a
voice mail message. Voicemail messages expire, and even if they did not, I
would not want them cluttering up my inbox. Most voicemail messages getting
rid of them is fine, but this particular one I want to hang onto
indefinitely.

How do I get the modem to "pick up" the phone? I.e., how do I get it into
the off the hook mode?

Here is what I wound up doing: I am using Phone Dialer (comes w/ XP Pro,
and I think it as comes with NT4 and up; 2000 and XP are basically upgrades
of NT4). On my machine this is located at "Program Files\Windows
NT\dialer.exe"
Using this program I am able to place phone calls, and whatever audio is
coming over the phone line is piped to my sound card. I can then record
this as waveform audio rather easily using some audio software (I use an old
version of Sound Forge by Sonic Foundry that came with a CD burner I bought
years ago).
This is ok for what, but what I would really like to be able to do is just
have a button that causes the modem to "pick up". Then I use it to monitor
calls in progress. Is there a simple way to do this, using a free program,
or just using a communications program like hyper terminal?
Thanks for the help!

This may vary from modem to modem, but my old modem used to play
through the sound card. (that was on an old computer with win98.) In
the mixer (accessed by double clicking the yellow speaker icon by the
clock), you could select the modem as a recording device. To do this,
you may have to go into the properties menu, choose 'recording' and
place a check next to 'modem'. Then select 'modem' as the input
source in the main mixer window. You could then record with a program
such as sound recorder, or my favorite, Exact Audio Copy (free for
download; google search for it).
Your modem and/or version of windows may not have this capability, but
it's free and worth a shot. Good luck!

The modem must have "voice" feature. That would appear in windows
device manager, I believe it's under the same category as the sound
card. As the previous poster mentioned it's accessed, selected
through the mixer and any typical application that can record audio
can record from a modem with voice capability. With the older modems
some had an internal line to the sound card's "TAD" or "Modem" jack,
often green-colored. Other, even older modems had an audio-out 'phone
jack on the rear which needed a patch cord to the sound card's
Audio-In 'phone jack, while some of the newer modems digitally
transfer the audio on the PCI bus with no extra cabling needed. This
type is conspicuous by having the voice feature but no output jacks
onboard.
