Where to Use EQ Match Reproducing a particular sound or duplicating a song: Here are some videos of the Fabfilter Pro-Q EQ showing how the matching function works. Here is a good article by Sage Audio comparing a couple of EQ-matching plugins (Fabfilter Pro-Q and Izotope Ozone): If you apply the required equalization from the analysis, what you end up with is your track sounding remarkably similar in tone to the reference track. The reference can be either side-chained (most matching EQs) or a stored spectrum (Fabfilter Pro-Q and Tokyo Dawn EQs) or a music file like mp3 or wave (Tokyo Dawn EQs). What the EQ Match function does is match the equalization of your track to a reference. I use both the Tokyo Dawn EQs and Fabfilter’s Pro-Q (version 3 at this time), but other manufacturers are including an EQ Match function in their plugins.

Using a reference track when mastering is a kind of standard practice, but it can be done much better with the wonderful EQ matching functions found on so many equalizer plugins.
