In my quest to modify the audio properties of the XMPCR (connected to the line-in on my carputer), I came across a program called "Virtual Audio Cable", which can process the audio from the line-in and converts it to wav in real-time. which can then be tweaked via software eq.

Virtual Audio Cable is a Windows multimedia driver allowing you to transfer audio (wave) streams from one application to another. It creates a pair of Wave In/Out devices for each cable. Any application can send audio stream to Out device, and any other application can receive this stream from In device. All transfers are made digitally, providing NO sound quality loss. VAC is a "wave-version" of the "MIDI loopback cable" like MultiMid or Hubi's Loopback drivers.

Anyway, my question is: does anyone know of any other apps like this? Reason being that it requires manual keystrokes to initiate the processing (which I can automate using AutoIT), but I'd also like to see what other solutions there are..
