Steal EQ from one song and apply to another

    I have two copies of the same song, but technically they are different (because the waveforms are not a 100% match).

    One copy is a commercial release. It is fully mastered and everything.

    The other copy is an early-mix of literally the same song (as opposed to a retake or live version), with no mastering and only slight differences (e.g., some vocal adlibs have been removed). It was obtained from an early reference CD before being outsourced for mastering.

    The commercial release sounds way better due to the mastering, but I prefer the nuances of the alternate copy. Is there a tool that can "steal" or "copy" the EQ spectrogram from the commercial copy and apply it to the alternate, unmastered copy?

    Has anyone considered this type of trickery before?

    I think I heard of a plugin that supposedly does this, but I just use my ears and an eq.

    There have been many incarnations of this sort of technology over the years, starting with the Steinberg FreeFilter. It sounded crap and didn't work.

    The plugin that MIGHT do what you're after is Paul Frindle's (Pro Audio DSP) Dynamic Spectrum Mapper (DSM).

    Be careful, though. It's deadly.

    Cheers :)

    If you duplicate the frequency signature of a hit and apply this spectrum shape to white noise, you won't obtain a new hit. Music is much more complex than a frequency print sampled on a 3 minutes period. This concept is plain wrong from the beginning. I suppose that was a marketer idea.

    Whoops did not mean to post twice but maybe I keep the image post separate here... This idea of using some formatted eq signature to apply to your own mix or master project is a waste of valuable time. To think your ears can't decide what sounds best and rely on your eyes or some programmable format will lead you down a dead end road. That sounds just outright lazy! Plus it's not creative or educational in many senses since your just looking for a short cut that actually might not make something even better, in fact it might just make it worse.

    I could sort of see using it to eq one instrument in a mix if I had one take with good tone but bad performance and another take with good performance but bad tone and I had no way to retake it to get the tone right. But I usually just use my ears and eq it.

    What DAW are you using? Logic has the Match EQ plug integrated in the app.

    Waves has the Q-clone, that does the same thing.

    Captures the sonic signature of the source, then applies it to your audio.

    EQ is not the only process applied in mastering. As others have said, use your ears, they are the most valuable plug-in you will ever own!
