    Hello everybody. I did some impulse response measurements in my music room. It's a room mainly dedicated to teaching activities, and I'd like to make it sound as good as I can. I made a QRD Schroeder diffuser, placed in the middle of the roof, and now I'd like to understand what I can do to...

    How does the (Average the responses) feature select the frequency where it combines the frequency response?

    Hello. I would appreciate some pointers on what I should do for my system. I am not sure if this is relevant but please note that this is a two channel system - no sub-woofer. It seems to me that the frequency response isn't great (i.e. not particularly flat) and that I have a reverb problem at...

    I took 3 sweeps at different volume levels (I calibrated each using SPL meter), no other changes. purple = 85dB green = 75dB red = 65dB The 200hz and up region is what I was expecting to see across the entire frequency spectrum. Look at how bloated the bass gets on the quieter sweeps. The 65dB...

    I'm getting a different response curve depending on how many sweeps I do. One sweep gives a relatively flat response, but the treble drops off the more sweep iterations I do. I'm using the UCA-202 soundcard and the UMM-6 microphone, with supplied cal files. To my old ears the response from...

    I must be doing something wrong as I do not get any response for my post. I have compared many posts and I think I met the guidelines. Please advise. Thanks

    I have been attempting to understand these charts recently in an attempt to assess whether the channels in my system are adequately time aligned (and out of general curiosity). As such I have a few, quite basic, Q's about the data. I believe the charts I have so far contain some measurement...

    Hi all, I finally got my system to work, did some first measurements today. I set everything up, did the calibrations and ran about ten tests with the EC8000 at the listening position. To my surprise about 5 of the measured responses were more or less the same (see fig.1 ) but the others had...

    Hi All, how do I make Polar responses measurements with REW? I am new to this program and just got my MiniDSP UMIK-1. I added the second picture just because it looks like a polar response.

    Hello, I am using REW to measure impulse responses and export them for subsequent processing with DRC. I would very much like to take the channel delay into account in DRC. This can be done if the impulse response is measured with respect to an external loopback as a timing reference. I though...

    Hello, Should I adjust the startpoint of my impulse responses? When using loop back as timing reference the impulse response window always start before the peak of the impulse. What does this mean for the rest of the graphs? Does it affect group delay and phase graphs? If I want to measure...

    Hi all First post here. Have run up REW and got it all working - the help files are way better than most! I've produced an IR and exported the .wav file - and exported the measurements to a .txt file as well and the results are what they should be for my room/speakers. Is it possible in REW...

    Hello everyone, I have attached pictures of my room responses, included 2 waterfall graphs. There is no eq except for a Marchand Bassis which boosts and adjusts Q of my sealed diy subs, set at 38hz. The room is extensively treated with broadband and two types of panel traps a la Ethan Weiner...

    First of all, thanks to Home Theater Shack for sponsoring this awesome software! After watching everyone else make measurements, I finally got the equipment together and learned how to use this software. This will really help in making objective measurements to help make improvements to my...

    I notice in this thread http://www.hometheatershack.com/forums/rew-forum/9526-equalizing-average-listening-position-warning-high-graph-count-ahead.html that in most of his plots the low freq. curves remain the same. I have noticed this in my measurements also. As long as I stay within a certain...
