I'm not an audiophile in the obsessive-compulsive sense, but I've been recording music in my home studio for 20 years and I know my way around it. This sort of calibration is not ideal. Not only are you measuring with a device that has an imperfect response curve, but you are also measuring the room at a single monophonic point in space. The way that sound interacts with the room and your ears is far more complex than that. Ultimately, this is a bandaid for a poorly treated room. If you're serious about getting a flat response curve from your monitoring room, you're far better off learning how to treat the room properly and how to position your monitors within the room for the best results.

You'd also be relying very heavily on the microphone used to measure it.

That's the 'device with an imperfect response curve', I assume.

In fairness, the readme does state:

> A good microphone is needed, with a wide frequency range and preferably with a flat frequency response.

By 'preferably' I assume it's implied that it can curve-fit (whatever's needed, I know next to nothing about this) to a non-flat microphone response, as long as it's known, but if it's flat then no need.

If it's unknown (and non-flat or assumed non-flat because it's cheap and doesn't make any claims about it) then that's the real problem, no point trying to do anything because it's like trying to construct a level floor with a shoelace for a spirit level.

i always wondered, is it possible to take a cheaper mic or iems and "flatten" them via an eq, to perform nearly as well as professional gear that's 3x the price?

i just picked up a pair of KZ AS06 iems [1] and my listening preference is U shaped (which is how these are dialed in out of the box), but i imagine with quality hardware and e.g. 3+ dedicated, drivers it should be possible to flatten them out in an eq.

AutoEq (https://github.com/jaakkopasanen/AutoEq/) does something like this so... yes?

But targets various HRTF curves which aren't neutral or flat, and they usually aim for a Harman target of sorts, so no...

But there are some neutral-sounding curves that seek to just emulate pinna gain, so they have a ~3KHz peak which is required to 'emulate' the natural resonance of your ear, which you don't get naturally when you jam a driver all the way into it.

There's no AutoEq preset for the AS06s. Here's a representative sample targeting the 2019 Harman in-ear target for the KZ AS10s for funsies though: https://github.com/jaakkopasanen/AutoEq/tree/master/results/...
