Record audio like Tivo or DVR?

[videophotogr]

It's happened to all of us, we are talking or just distracted on a call on the scanner that turned out to be important...but we didn't get the address or important details. Is there a software program that will allow my computer to act like a Tivo or DVR? What I want to do is pause and/or rewind live audio to while still recording? This seems to be a simple request that technology should easily do. I've tried searching the archives here but not with much success. Any help?

I was making this for Scanner Force but got distracted with real life programming. I have the rewind part, but it was buggy so I stopped making it for now. I plan to pick it up once I have free time, but that's not going to be for a while. Good luck finding one. I'm sure its not hard its just that it won't be integrated like mine was designed!
