The "deprecated" side of things was pretty clear with the original entry. I suspect it was your handiwork marking it as such. Nice.
I expected that audio was the objective, which is why I did a Wiki search and posted the URL. My unashamed philosophy is to point everyone, myself included, to the Wiki. It's not perfect but it contains the answers more often than not.
To record live streams with your computer, you may want to check out:
* Audio Hijack for Mac: If you have a Mac, this is a highly-recommended app.
* Total Recorder for Windows. I haven't used this because I'd just use Audio Hijack on one of my Macs, but the Rogue Amoeba folks recommend this as a decent Windows alternative.
Audacity might be another option. I leave the reader to search the web for a link.. just for fun ..
