Greetings,

Have enjoyed my fast tracking of relearning audiofilliness, courtesy of this forum and others.

My first foray into Room EQ was with MathAudio and Foobar using the very helpful post on here https://www.audiosciencereview.com/...ds/mathaudio-room-eq-users-tips-tricks.30525/

I used this microphone as it was the only one I have https://www.amazon.co.uk/gp/product/B07GVGMW59 and had it mounted vertically in various tweeter height positions around my sitting location.

I attach a photo of my listening position.....BTW my ears are not in my toes.

The effect of applying Room EQ was significant and very revealing.

I appreciate the final end result distils down the listener but I was hoping for some feedback on the curves and where more learned audiophiles would position the cut off. It would be useful to know if the curves reveal whether the microphone I used is suitable.

Thank you in advance for any useful insight you may share.

Applying room correction with that mic is like building a house with a hand-painted yardstick :D

If you're looking for a cheap, accurate microphone, then take a look at the Micbooster EM258:
 
As @staticV3 said,but even with a good mic the drawn line should be around -7dB area if the response looked like that.
 
1) Try to use a more accurate mic as @staticV3 said. Honestly this mic is just as likely to make things worse as it is to improve things.

2) As @Sokel mentioned you probably don't want to reduce gain that much.

3) It's questionable to apply correction to the whole frequency range like this, generally results are more reliable if you stay below 300-500hz depending on the room.
 
Thank you for the suggestions.....EM258 ordered.
 
Here are the results with the EM258 that arrived. I positioned the mic vertically, rather than horizontally. For these new measurements I have the speakers positioned in my preferred location.

I now need to understand where and how to reduce the gain.

Careful, I blew two Nautilus tweeters , Maybe don't do at high volume.
 
MathAudio is a ridiculous program with very poor functionality that can’t even export filters to formats that other programs can understand (for example, Equalizer APO), but the programmer wants to be paid $100. I recommend Cavern QuickEQ, which is free and has a lot of features.

Thank you for this tip - this led me to https://www.audiosciencereview.com/forum/index.php?threads/cavern-quickeq-basic-how-to.32770/ I am a multiroom LMS user so the option to have EQ in LMS using SqueezeDSP will be very useful.
 
study the topic so as not to ask ridiculous questions
Ridiculous?

The author of Mathaudio states that his algorithms produce more accurate results than any manual PEQ (eg EAPO) could possibly do.

So, unless you have solid evidence otherwise it sounds to me that your postulations may fall into the ridiculous category.

ASR is not focused around views that aren't backed up with any facts (aka opinion) which is nothing more than what you've given at this point.
 
The Foobar components can be used free of charge.

The VST/AU components are paid.

See the download page.

sorry for being a bit thick, but is there a way to expand the pop up window for this?
i can barely read the info on it
