    Hi All, I would like to ask a general question about room correction: What shall be the ideal order of the followings: - Room correction EQ - Speaker distance setting - Level setting - Crossover setting Currently the order I have is the following: Crossover -> Distance -> Level -> EQ But I was...

    Hi all, I've been speaking to a audio guru about an active speaker setup that I'm working on and he's said the phase response is critical to good sound. I know we can view this in REW, so can we do anything about it with the minidsp? Or is it all about overall design? Appreciate your thoughts...

    I am experimenting with REW and what I will call Inverse Deconvolution IR Convolution Room Correction. I have a way to also limit too below any frequency (example: below 500hz). Would it be best to export measurement as just regular impulse, or minimum phase? Another way of asking, if one was...

    I have a subwoofer, matched to my studio monitors. If I attempt to measure just the left and right,seperately... Since the low end with crossover on sub @ 80hz, is constant level, while the left or right are playing alone.... this puts the sub at high level, and Studio monitors of course lower...

    Is there any standalone multi-channel EQ hardware, possibly MiniDSP, that will work with an Atmos receiver?

    Hello, I see high interest about the subject here. I would like to offer my expertise collected in 14 years of serving professionals. Let’s start with discussion with Dr. Floyd Toole about his paper "The Measurement and Calibration of Sound Reproducing Systems"...

    Hi, I was wondering, if anybody knows if it's possible to use spectral subtraction for room correction? Background: I experimented a lot with correction, since my room has really bad acoustics. In the current state I have some absorbers for highs and mids, and use simple, aggressive...

    I have been studying REW video tutorials and the manual for days. I initially had problems getting things working but have finally made it through these steps: Calibrated soundcard via feedback loop Calibrated SPL, balanced mic input to match pink noise Did the sine sweep to measure the room...

    When the correction value for the 33-4050 Radio Shack SL meter is say minus 0.93, do you subtract this number from, or add this number to the raw spl reading? Thanks. Zarka.

    hi there i am pretty new here.. i measured my room and apply fix using equalizerAPO now how do i measure my room again after applying the fix? i have created pink noise audio file and its looks pretty good ot the RTA but can i measure it with sine sweep through REW? Btw i am using samson C02...

    Hello fellow members, I am trying to tune my active car audio setup. It has a 3-way active head unit. I also have both the Dayton and Umik USB calibrated mics and a multichannel USB sound card. Is there a concrete method in REW to both phase correct and time align the individual drivers. I...

    Hello everybody. I'm very new to all of this, I will do my best to be as precise as possible. I bought a NanoAVR HD in the hope to improve my systems sound. I've read a load of tutorials, which aren't always as clear, but still remain with alot of questions. I will go through the steps I took to...

    Greetings! I have a HT system with High-End gear. My speakers sounds superb, however they (or room actually) still need some correction into 20-200 Hz frequerncy range. I have read HTShack's guide to proper correction with Audyssey XT32. The result is indeed (geometrically) beautiful FR. Sound...

    Hello everyone, I'm new here, and searched the forum, but didn't find anything to my problem. So I have an older reciever, Pioneer wsx 323 that not supports MCACC. I decided to do room correction with REW. I made some measurements with a Behringer ECM8000 mic, and applied automatic correction on...

    One of the most intensely compared features across AV Receivers is onboard room correction. For the lucky few (with perfectly shaped and treated theater rooms) this may be less of a concern, but for the vast majority of users some sort of correction is necessary to squeeze the most from a...
