Hello all !!
I want to record audio output from sound card in my Fedora Linux 11 (from
any generic audio source streams). But unable to do so with existing Sound
recorder. Nothing gets recorded when i do so.
I am playing Shoutcast radio online in my browser and looking at many
websites i tried to do some steps on vlc,audacity etc etc. nothing works.
Moreover those websites ask me to download the metafile and look for
mms,rtsp and stuff like that and the do the recording stuffs. im unable to
get those metafiles.
Given this case is there a generic procedure to record audio output from
sound card in my Fedora Linux 11 ?
Any help is really appreciated !!
Thanks

Try pavucontrol. (I don't know if it's available on the Fedora 11 repo
though.) I found it via:

Often, but not always, when you have one of those metafile URIs, you can
give the address to mplayer, and let it handle it.
e.g. mplayer -playlist http://example.com/playlist.m3u
(likewise with various other protocols than HTTP).
If that manages to play it, then you can so something similar, adding
dumpstream options to the command line. To pipe the output to a file,
instead of through the sound hardware.
mplayer -dumpfile savedfilename -vc dummy -vo null -dumpstream -playlist
http://example.com/streamname.m3u
Then, if you want to monitor what's happening, you can play the file
being dumped to the drive, *as* it's being dumped, with another instance
of mplayer. Just wait a while before issuing the command, so that
you've got enough of the stream downloaded to your drive.
mplayer savedfilename
Messy and convoluted, but I've done that with a radio station stream
that was impossible to listen to live (it kept on stuttering).
is there a generic procedure to record audio output from sound card
in
my Fedora Linux 11 ?
Well, to answer your query literally, if you want to record the audio
that's put out by the card, it is possible to connect a patch lead from
the output socket, back to an input socket, and record *that*. Be sure
that the input socket doesn't go back through to the output, as well.
e.g. Sound card line out to sound card line in.
Line in recording volume control turned up sufficiently.
Line in monitoring volume control completely off.
There were some sound cards that did make it easy to record the output
data just by playing with the mixer controls. But if you had one of
them, you'd probably have found the controls to play with, by now.

That's exactly what I mean.
What else would the driver send the sound card? TEXT???
I am talking about OUTPUT - that a shim can capture the output
PCM data.
I know that's what you mean. Was that not clear from my last reply?
However the OP wanted to capture the output *from* the sound card, not
the output *to* the sound card. I just said that taken literally I
didn't think that made sense.

Stop. Take a deep breath. Read my various posts again. *I'm not

It may well be. I make no claim to be an expert, but the OP did say "the
output from the sound card" rather than the PCM data being sent to the
sound card. This leads me to think he isn't any more of an expert than I
am, so he may have been mistaken in what he thinks he wants to do.
Be that as it may, there are ways to capture streams from online sites,
though they often need a bit of tweaking to get right, e.g. RealPlayer
is one thing, Flash is another thing etc. etc.

Jan:
I've never used it, but there is a program called streamripper which
may meet your requirements. It's available from rpmfusion, and carries
an .fc11 suffix. FWIW, it can be used with streamtuner (a web radio
station finder and tuner) which I have been using for a long time with
considerable success.

Not the answer to your question, but might be the solution of your
problem:
You should try mplayer. It can dump the stream to an raw file.

AFAIK you can't record directly from the *output* of the sound card. The
sound recorder is for recording input.

If your browser can play the stream, you can capture it. However it's
not a one-button procedure. You need to check exactly how the stream is
being downloaded and figure out how to intercept it. mplayer is pretty
good at this once you have the right URI. In fact it even has a specific
mode for capturing radio streams.

No. As I said, recording from the output is not supported. I'm not even
sure it makes sense.
Also, note that F11 is now unsupported. You should upgrade your system
(that won't solve this problem but you should do it anyway).

someone had emailed me quiet a few years back that the
driver sends pcm data to sound card. So, it is possible to add
a shim to capture (i.e. copy) that pcm data.

Attach a "minijack to stereo phono-leads" to the speaker output,
and the other end to your Hi-Fi system aux input.
