    Did you point mic to speakers?

    Microphone placement for measurements

    Let say I did all 3, all graphs are different, which one should I take as a base for correction?

    Microphone placement for measurements

    I'm wondering if there is a common opinion on microphone placement for measurements. For simplicity, let assume we're measuring at one point only being the main listening position and frequency range > 150hz. Obvious choices I see are: 1. Next to the ear measuring speaker on the same side - the...

    Weird auto equalization issue

    John, very much appreciate. Many thanks!

    Weird auto equalization issue

    If you don't mind, I'd like to ask few things. 1. Why, in your opinion, 4-6 or more db deeps aren't matter. 2. I limit max gain to 1db to not math-overflow DAC. Do you think the limit could be higher, at least in higher frequencies? 3. My understanding of Harman curve is (a) it is...

    REW measurement timing instability

    3ms is surely a lot. Thank you very much Mitch, it's clear now. Really appreciate your thorough explanation and especially your time spent on it. Cheers.

    Weird auto equalization issue

    I was not aware of this, John. My understanding was, and it is actually happening, is that if target crosses the measurement then those areas below the target will get even deeper below with neighborhoud regions "helping" this to happen. My listening area is as bad acoustically as it could get...

    Weird auto equalization issue

    In a past, I was advised to do this so that file can be attached. Apparently, it's no longer a case. I unchecked "Vary max Q above 200hz" but it didn't help. House curve is attached. On a side note, I'd rename "Vary max Q above 200hz" to "Variably limit max Q above 200hz".

    REW measurement timing instability

    @Mitchco: my apologies for confusion. My problem is that I don't have an analog mic and it's unlikely I will ever have it. So I'd like to keep it purely theoretical, just to have some level of understanding of a degree of errors that could be produced by using USB devices for both input and...

    Weird auto equalization issue

    Would like to return to this subject. Attached are mdat and few pictures of equalization results. Images named "...calc target level from response" are equalization based on suggested target level of response. As you could see, in both area around 15.5khz is not corrected even though the gain is...

    REW measurement timing instability

    I recently had a discussion on Audiolense forum regarding using UMIK-1, and USB mics in general, for mesurements. As I understand, AL mostly doesn't work well, or doesn't work at all, with USB mics. When I mentioned that I never had problems with REW, I got this from Bernt (AL creator): "Mitch...

    Weird auto equalization issue

    Sorry, forgot to attach mdat but it's no longer exists. Will post next time when I see this behaviour.

    Weird auto equalization issue

    In this particular case "match response to target" leaves area above about 11Khz unaffected, leaving almost 5db gain, despite having 2 unused filters, but there is one generated 15.5khz filter but it has 0 gain. Tried various target level values with no effect. I've seen this behaviour before...

    Few questions from potential AL user

    What's the right site to download ASIO4all? Looked at https://asio4all.org/ - looks like crap and feels unsafe to download from.
