Real Time Audio Recorder, where do i get one? Options

[leavinghope]

so im looking for something that's going to record internal audio as it goes on inside my computer..


not streaming audio per say.. but as if you were recording whatever audio was happening on my computer. i tried a couple programs, but they only sources available to them were the internal modem (records static and stuff), the built in mic, and the line in. none of these things (to the best of my knoledge) are going to record what i need it to records. a few years ago a friend of mine had a program (what i don't remember) on his PC that recorded internal audio. This kind of technology would allow you to record the audio that's going on from say a live concert dvd playing on your computer... not by ripping the audio but by recording it in real time. and the quality sounds like it was taken from cd or something. if anyone can help.. awesome.
