Windows Process-Based Audio Output Recorder and Mixer

Question

This utility probably doesn't exist. If it did, I would probably already know about it. That said, is anybody aware of a utility that can record and mix audio on a per-process (or audio stream) level?

For example, let's say I'm playing Portal 2, and I want to capture the audio from the game, the audio from my partner, and the audio from my mic, all independently, such that I can combine them at a later date without fear of messing up the levels.

The audio comes from: skype.exe, an input device, and portal2.exe.

Any recommendations?

I've used Virtual Audio Cables several years ago. I remember it did work as advertised (I used it to send Skype audio over the network as SIP, and it kinda worked, but there were issues: latency and sync., if I remember correctly. This was many versions ago, though).

Virtual Audio Cable software allows you to transfer audio (wave) streams between applications and/or devices.

It creates a set of virtual audio devices named "Virtual Cables", each of them consists of a pair of the waveform input/output devices. Any application can send audio stream to an output side of a cable, and any other application can receive this stream from an input side. All transfers are made digitally, providing NO sound quality loss (a bitperfect streaming).
