I was in the mood to tweak as I was unsatisfied with some subtle (I thought) sound quality issues and decided to go to the oracle to see if it could help. And did it ever. First we futzed with the upscaling and other settings, then it suggested I add MEqualizer, a free (with paid option) plugin to balance some bass bloom and upper-mid details. I’d already had HouseCurve on my iPhone and it had me do a sweep with it and upload the image. It suggested what to do in MEqualizer with great detail to balance out the curve, and it was spectacular. I compared ChatGPT with Gemini and there was almost exact agreement on the sweep interpretation and the MEqualizer settings.
I always do my due dilligence with three AIs…
BTY, I use REW, a UMIK-1 USB measurement microphone and a Pro Mic Stand… I wonder how much variance there would be between our two measurement systems? If you hold your iPhone in your hand your body will influence the measurement…
And good job getting to level 1 my fren…
Are you implying in that statement, measurements should, or should-not entail the shadowing and reflectivity of the body and head? ![]()
Go ask ChatGPT, Gemini and Perplexity… ![]()
You made the statement… I know what my approach is, and why I believe it provides the most realistic picture of the subjective target listening positioning.
It worked.
I rigged it up with a tripod and a wooden dowel. Ducked behind the couch.
Is this how you listen to your playback? Ducked behind the couch? How will a chatbot know what this sounds like?

Don’t be ridiculous… It is called Room Correction not Person Correction… And there and several measurement techniques… Only the moving mic technique would need a body in the room and that technique cautions about holding the mic with your hands…
Do you listen to your playback through a calibrated microphone?
No, and I do use a calibrated measurement microphone to sample the speakers in the room… From the Main Listening Position, at head height…
Does it look like this?

No, I use a miniDSP umik-1 usb measurement mic… Good enough for residential room correction… I also have a Dayton Audio UMM-6 USB Measurement Microphone which is very slightly less accurate…
However, I do use the B&K House Curve described in their document https://www.bksv.com/media/doc/17-197.pdf
No doubt that it can be an acquisition reference… but something is missing.
No doubt… REW software which creates sweep tones and records the measurements… And a method of creating room corrections be various methods using REW itself or other Apps and tools…
Acquisition software and application methodology is a given…
I guess the missing part is the knowledge and skill to go through the entire process of setting up for measurement, measuring, interpreting the measurements, making the correction choices, creating the filters, loading them into the entire signal path, remeasuring to ensure outcomes match predictions… And, of course, using your ears… The nice thing about the HLC is you can load six different FIR filters and switch between, in realtime, to do A/B/C/D/E/F comparisons…
I see it in the fundamental acquisition process, where a specific set of measurements are not captured in the averaging, that have bearing on the subjectively perceived sound-quality.
Ok… REW captures SPL, Phase and Time… All three can be corrected with various methods and tools…
Maybe you would enlighten us…
I’ve already alluded to the missing measurements… How these are acquired is relatively simple, given the available tools you have at your disposal… and those measurements can be optimized for the subjective real-world experience.
