I rather like the program proteus, it is extremely powerful, and can do things i never even imagined possible (such as simulating an ARM7 booting Linux and having interactive touch sensitive LCD's).
I was wondering if you could take an input, from, let's say, mic in, and make a circuit to interact with it, such as simple distortion or treble booting, and expect a real-time simulation and an output via speakers? Or would my best bet be to record the input as a wave file and use that as a generator input?
I have 2gb of RAM and a dual core 3.60GHz processor.

As long as your simulation runs in real time it should work, there are also some plugins made for other types of realtime input and output. Using prerecorded input is more reliable since you don't have to think about the realtime aspect all the time.
Proteus is great, the main problem is that they have given up on the shareware version and their forum is at times as helpful as a spool of barbed wire.

If you are looking for mostly analog simulation functionality, the LTSpice SwCADIV (SwCADIII has been superseded) is perfect for the task you presented. The only key difference between what Proteus and SwCADIV can do is that SwCADIV cannot do real-time simulations; it can only perform discrete transient-analysis simulations (along with other AC signal analysis functions).
However, as Bjørn mentioned, you can achieve the task with prerecorded sound files, and SwCADIV includes very simple and effective commands to import WAVE sound files as input signals in the simulation. The output can then be saved to a WAVE file using another simple command. This file can then be listened to for the result.
If you intend to do complex digital simulations, I would still recommend Proteus as the most useful program. SwCADIV has limited digital simulation capabilities, as it is designed to perform simulations on power management systems and their associated digital control systems.
By listing some specifications of your computer, I assume that you are wondering whether your computer hardware would be capable of doing such a simulation in Proteus. Considering what you have, I see no possible problems.
