Maybe it's a kind of audiophile plaything, and maybe it will not work out in practice. However, as audiophile playthings go, at least it has some degree of measurability. You could probably guess that I would have no time at all for some sort of idea like,
HF hearing loss? try silver cables! :lol:
In my humble experience, it is quite difficult to get EQ right --- or even comfortable. Perhaps that's why sound engineers need training and experience
. My in-the-end current status is that I have turned it down quite a lot from what numbers might have suggested, to a quite subtle rising curve above 1k, which recovers at least some of the brightness in the music without making it harsh.
As well as a project, it is also very much a learning exercise. People talk about frequency response; they even recommend sampling rates that take it way above what
any human can actually hear, but I suspect that only a few of them have ever looked at charts, played with EQ, etc, and found out what actually happens at what frequencies, and how the
majority of the sounds that make music actually happen at relatively low frequencies.
With roll off at 8k, I am deaf enough to find phone calls difficult, and to find conversation against a background noise impossible --- but I don't actually miss
that much music. Enough to make a difference, yes: the same blurring of words happens in vocal music as in conversation, cymbal swish is missing, and the thing that we call "air" is not there at all. There may not be much in those higher frequencies, but that is not to say that it does not count.
Decadent_Spectre, excuse me if this is a bit if a hijack, but I hope it comes under the same heading in talking about music, hearing, frequency range and possible corrections.
