1) I wholeheartedly agree I'd like more control over the correction, I'll just expand on it a bit. A
"cut only" mode for frequency ranges of the user's choosing would help tons where the correction makes the situation very noticeably worse, or simply where it is overdoing it where it would have been fine with less gain in that spot of correction.
For example, this would really help me lower the volume of the peak at 54 Hz whilst keeping ARC Studio from trying to boost my speakers in the frequencies below where it only causes quite audible issues to boost them since they're built to roll of at that point.
Another common issue it would solve is where ARC Studio tries to boost a null it shouldn't. (Maybe my fault too considering I use only one spot to calibrate? I assume there would be an attempt of null detection going on somewhere aided by the different measurement locations you're supposed to use. But maybe I'm way off on that. It also wouldn't help if the null basically covers the whole measurement area.)
I have lowered my target curve over the whole spectrum to -6dB which really helps, but of course removes the possibility of boosts where I'd actually would have liked to use them and I also can't roll any other frequency with the target curve manually now.
This feature would be, by far, the most important improvement to me.
The rest is just small stuff:
2) A measurement creation mode that allows you to simply measure the same spot a few times. Currently I just measure the same point seven (was it seven?) times since it gives me the best results for my needs (just me in my fixed listening position).
3) Calibration file for the mic. I'd really like to have some hands-on proof that my measurement mic is working as intended. It helps keep me sane.
4) LED on the CORRECTION button just a little bit less bright. I tend to see glares around bright objects in the dark and this LED is actually annoyingly bright in comparison to others - the other two LEDs are fine and have never bothered me.
Also, thanks for making this. I love the set-it-and-forget-it of the hardware version, it does a great job overall and I'm happy to have it here
