I listen to music on on my computer but the volumes of the songs are all over the place when they stream. Sometimes you get a soft track, other times you get a really loud one that makes your ears bleed.

How can I normalize the volume in real-time on a Windows XP computer so this doesn't happen?

This DirectShow filter might help, depending on whether Flash uses DirectSound:

If it doesn't, then I'm not sure what else to suggest, unless your driver software has support for dynamic range compression - it might be worth identifying the sound chip and downloading the requisite suite of software from the vendor, sometimes they will have an option for loudness equalisation in their bundled software.

One thing to note though is in Windows 7 at least, loudness compensation is built into the operating system.

I've seen positive feedback about Breakaway Audio Enhancer, which seems to do exactly what you are asking. Unfortunately it is not freeware though, at $29.95 with a 30-day trial.
