What is a utility for capturing the stream coming through a sound card to file? Windows has had little simple apps like that for years.

Mplayer will capture to file with
mplayer -dumpstream -dumpfile name.wma http://site/media.wma for example.

That is just for streaming content from a site. Mplayer will also play a local file of course. It's not real easy if at all to get just a segment of the file or stream though. You have to start at a time postion and then stop at another one.

What I'm looking for is a utility that will record - stop where I want as I play a media file or stream and save it to file. To edit a media file.

I've got Krec but never figured out how it works. There should be a utility that will capture what is coming through the sound card, then save it to file as a media format, then it does not matter the media format of the original file or stream. Yes I understand it'll have to be a full duplex card to play and record at the same time. I have looked around a little and haven't found a simple little app yet.

I would like a open source app that is ported to Linux and BSD. I'll take what I can find.

Thanks.
