Default software to compare audio files

i have eq'd a number of .wav files, but i did not note down my eq settings.

is there a piece of software that i can compare two files so i can see the difference between eq'd and non-eq'd?

How about, taking a screenshot of each, then overlaying/mixing them accurately. If you overlay/mix the second one by making it more transparent, it "should" work

Here's a VERY quick example, which i didn't spend much time on, so isn't 100% perfect. But you should get the general idea

I used the Free Xnview to do it !

I did compare 2 audio files in my screenie, with amplitude versus frequency ! I only showed the bass range, just as an example of what could be done with this method. This was a fairly straightforward way of visualising the difference

You could use the very nice Spectrum Analysis etc tools in for eg, Wavosaur. Also free is Audacity which has some SA tools too.

And with either of the above, before the SA, you could invert one of the files, mix it with the other & save it. Then analyise the difference. Make sure you don't clip the files.

I've just tried All the above & it works fine
