Useful for calibrating cheap speakers at zero cost.

Counter-point: The use case is making relatively-shitty speakers in front of the computer better, and single point in space isn't really that much worse than trying to somehow…
xani_ on HNSo many negative comments here. I for one think this is absolutely fantastic tool to calibrate cheap television and computer speakers so they don't sound like complete crap.…

Could help with headphone and EQ tuning.

It does however look great for helping me characterize differences in my 3D printed headphone designs. My old resin-printed design has incredibly good bass, and when I changed…

Objections
Room correction is a bandaid; proper room treatment matters more.
From 2 comments
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…
IAmGraydon on HNThis type of software, is just a bandaid and really doesn't work very well (though it can work better with headphones). Properly thought out and tuned acoustic work is what is…

Results depend heavily on the measurement microphone's accuracy.
From 2 comments
You'd also be relying very heavily on the microphone used to measure it.
drcongo on HNThat'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…

Frequency response changes with volume, so one correction may not hold.
From 1 comment
I’ve tried this for my speaker setup. And the problem is that the frequency response is a function of volume. For example, the louder I play music the more the bass is…

Requests
Support for better microphones and calibration files.
From 2 comments
Commercial systems that do this kind of room correction generally have a limited range of recommended microphones, and the more expensive (and hopefully better) ones will have…
rodgerd on HN> A good microphone is needed What qualifies as good enough? Is it worth trying with consumer mics like the ones built ins on phones and laptops?

Phase and nonlinear distortion correction.
From 1 comment
I think it would be cool to make a more advanced version that corrects for many types of nonlinearities: amplifier distortion and mechanical parts resonating badly.

Questions
How does it compare to Dirac Live or REW?

How does this compare to dirac?
LeSaucy on HNI wonder what are the differences between this tool and industry standard REW app - https://www.roomeqwizard.com/

Can consumer microphones be used?

> A good microphone is needed What qualifies as good enough? Is it worth trying with consumer mics like the ones built ins on phones and laptops?
tambourine_man on HNNewbie question: how do we know we can trust the microphone? It sounds like a chicken-and-egg problem to equalize speakers with an equalized microphone, but maybe microphones are…

Dirac Live

Have you tried Dirac Live? Particularly with a receiver that supports their Bass Control feature? My NAD receiver only supports regular Dirac Live and it's still much, much…

I'm using the commercial https://www.sonarworks.com/soundid-reference and it's amazing. I'd say the worse your setup (especially your room) the more magic it does. I did it…

There is an older project with better math inside: http://drc-fir.sourceforge.net/ For starters, it doesn't try to achieve a phase-neutral response, because a phase-neutral…

Asking because I'm not smart enough: Is this kinda similar to what the Sonos Trueplay feature does? (Where you move your phone, and/or a mic-enabled speaker itself, around the…
