Thanks Joe, I'll check out the Discord. BTW I forgot to mention I did all the measurements from the MLP equidistant from L and R. And the speakers had already been aligned with Dirac Live, so the impulses should be on each other within much less than 1ms.

Hi Joe ... no I don't think that was me on the Discord. When I just use REW and measure my left and right with the timing reference from the left channel, the delays are -2.0196 for the left channel and -2.1785 for the right (leaving that checkbox checked). REW sends both chirps to the left...

Forgive me if I missed this if it was previously discussed in this thread ... but what about Fletcher-Munson? If someone mixes at 75db or 85db reference, then the aspects of the perception curve will be baked into what they heard, right? And if we listen at a different reference then we may or...

I have been using this for a couple months and it's a great tool! But I have noticed something and maybe someone can confirm if this is working as it should. When doing REW measurements using the Impulse Response sweeps #11, the second timing chirp is coming from the speaker under test and not...

Okay, I tried two things. Since I last ran REW measurements I had done a Dirac Live calibration and loaded filters into my processor. I was measuring the result with ea58. So I went back to a Dirac calibration from early April and found the measurements with ea58 to be the same as I...

Wow, okay ... well I'll reinstall the previous build and test again. I can't imagine what would have caused this on my side. Thanks!

I installed the latest build this week. I've been using V5.20.14 for a month or so (ea 45, 47). With ea58 that I installed May 9, the sweeps are playing about -10db quieter than they were before, all settings being unchanged. And without checking the LFE -10db option, it now measures same...

Great story! Floyd Toole (and certainly others) have written about this adaptability of our brains connected to our ears. Now I have two questions: Is it possible that after a while the neighbor's TV didn't sound "the same" as your TV, but rather it no longer sounded different? And, How...

Yeah I'll definitely check it out too. Saw Gadd with Chick a couple years ago ... he's still got it even at 75+

In the video I posted above Johannson spends a lot of time talking about what can/should be corrected and what will cause more harm than good. I don't think I have read anything from Toole on Impulse Response correction, nor do I recall any of the other room correction systems talking about it.

Interesting discussion with the CEO of Dirac Research. Some of it is specific to how Dirac works, but it's also a good general discussion of time domain and frequency domain issues and possible methods of correction.

Absolutely! If you are listening to anything below reference levels then a Fletcher-Munson-esque loudness compensation would be appropriate. I see people mixing this up, and suggesting you need loudness compensation all the time ... and okay if someone wants more bass fine, but there's no...

I think the posts in that link are reposts of Floyd's posts, aggregated into one place. I'm not saying the studies and data were not useful, at least to Harman. They're in the business of trying to correlate consumer preferences to speaker design. But #1, these curves represent the personal...

Oh okay .... this one ... https://www.audiosciencereview.com/forum/index.php?threads/some-comments-from-floyd-toole-about-room-curve-targets-room-eq-and-more.10950/ BTW, I was looking for evidence on the use of the "Harman Curves" as EQ targets for speakers. I have yet to find what I'm...

In the 2017 study published in AES Convention Paper 9855 (after Toole's era) they reference Steely Dan Cousin Dupree as being from previous studies. In this study they used the following in addition: DeadMau5 Ghosts n Stuff; Drake One Dance; Emmylou Harris Black Caffeine; Bruno Mars Uptown...
