Take the wav, dump it into ableton and let it render it's analysis file.

Then just go through the mix and tweak it where needed by removing frequencies rather than adding them, many people say this way of tweakig sound is much better than amplifying the signal up to the surrounding levels. Most likely because if you add in some EQ it distorts the signal more than subtracting from it so when you finally do normalize the signal which just multiplies it, it keeps the distortion from being amplified as well.

Ableton seems like the tool of choice to do this due to it's easy to use automation, you can just loop stuff and keep tweaking until it sounds correct then move onto the next part you need fixed and just keep that up to fix any discrepancies in the levels between transitions.
