    I have a patent on "content aware" EQ, applied for in 1997 and granted in 2002:
    https://patents.google.com/patent/US6341166

    I've probably mentioned it 3 or 4 times in the last 20 years or so.

    It was completely re-written and mangled by the patent attorney who handled it, LOL!

      As a matter of interest, has anyone made this commercially?

        Good question, I've not been in touch with LSI Logic who originally owned the patent, however,
        I asked the VP legal dude who asked us to produce patents if they would ever build it and he
        said probably not, they just wanted as many patents as possible in their portfolio in case of
        patent wars.

        I've never tried to find out if anyone implemented it.

        It was cited in 59 new patents so there seems to be a lot of interest.

          This article provided some ideas for that patent:

            Hey Pete, is it possible to explain in a few non techno terms how your method worked?

              I'll try to get to this in the next few days.

              My motivation for wanting "content aware" EQ was the frustration with voicing my speaker designs
              to sound good on the majority of recordings - I found, banging my head against the wall, that it was
              not possible. So I just chose 10 or so of the best recordings for voicing, then the idea for content
              aware EQ came to me.
              It even drove me to purchase really excellent commercial speakers to use as a reference, if a CD
              sounded bad on my speakers I got another opinion on the reference and headphones.

                I have a feeling this is going to be hugely educational for me.

                  You should give the software I suggested a try. The results were pretty impressive, for the brief time that I tried it.
