    Need to check a measurement mic frequency response and of course a speaker will color the graph. I have heard an Air Compressor can be used to generate full audio spectrum Pink Noise. True? Other sources of Pink Noise? Or.. I there a good DIY way of getting an accurate frequency response graph...

    Hi, I have been successfully using my calibrated mic with .frd file in REW for some years. It corrects for frequency response, but I assumed it doesn't correct for sensitivity / SPL. However, I recently came across a message in REW that I don't need to go through the sensitivity calibration...

    I hope that I am not posting this in the wrong place. My apologies if I do. I am trying to figure out where the flat line comes from starting around 12kHz, as it seems to be only happening with my speakers. I am not sure if this is the mic, as it produces different results per different...

    I am little bit confused where to start the room acoustic analysis for Home theatre setup. First priority is for low end and the second priority is for mid and high end analysis. My question is Whether to choose SPL meter with line out like galaxy audio cm 140 or linear condenser mic like...

    Hi I am setting things up for Rew measurements. I already have the UMIK mic. reading through the instructions I saw that I also need a boom mic. Will this one: On Stage Stands MS7701B Tripod Boom Microphone Stand work well? It is from Amazon. Sorry I can post links right now. Or is there...

    Hey there, I got my measurment kit since 10 years. It was calibrated by a company that no longer exists. I tried to convert the cal in exel to a 90 degree one like this one in my picture. Don't need that 100% correct. It's just more convenient to measure in 90 degree. Anyone could help me...

    Hi, I'm going through the REW Step-by-Step guide (Rev 5.43, June 3, 2017) and saw it recommends using a boom mic stand. What, if any, is the advantage of a boom stand over a cheaper, generic mic stand? I can find generic mic stands much cheaper and don't want to spend the extra money for...

    So my cats have decided to chew through my MCACC microphone cable for my Pioneer sc-lx83. The AV receiver is dated 2011 and Im having trouble getting hold of a replacement for it due to the age. The part number is APM7009 and I have literally gone through every link google has given me. The...

    Pardon me if this is a dumb question, but can I use REW to measure the difference between two condenser mics that have 2 rings mini headphone jacks? I know it won't be anywhere near "accurate". I basically want to verify that they are "equal" in response. As crazy as the response curves might...

    So I'm trying to find out if my McIntosh mic from MX150 pre amp or MEN220 Room correction system (both the same mic) will work with ReW. I was planning on getting a XLR to USB to connect it to my laptop, as I am trying to use ReW for a car system. Obviously there is no calibration on ReW for...

    If this issue has been raised before, I couldn't find it. Please point me in the right direction if it has. My bottom-line question: "Is it possible to use REW in ASIO/HDMI mode with a preamp/mic instead of a USB mic? I'm now able to send test signals to each speaker without switching cables...

    Hi All Just wondering, if for the Measurement mic in REW, if I can use the Anthem mic I had with the Anthem ARC program. I no longer have the receiver, however I can buy the Mic and stand and Calibration files for about half the cost of a UMIK-1

    Hi everyone! My mic stand busted at its 360-degree swivel joint (in the horizontal plane), which is threaded but won't seem to screw back on. I have to basically push it down so that it snaps into place, only to have it snap back out again after only a few swivels. Sorry, I don't remember the...

    After years of using an Oppo BluRay player as a preamp/processor, I now am using a Nuforce AVP-18 processor that only accepts HDMI inputs, which is fine as all of my sources are digital. I have read that REW now will allow signals to be generated through a HDMI cable and I am anxious to use REW...

    I'm seeking advice on how to set up REW to output over HDMI and input via a USB Mic (calibrated Emotiva EMM1) on a Mac book pro. I had it working a couple years ago but at the time the only was I could get it to work was to use two third party applications, Audio Line-In and Soundflower. Audio...

    I've been using an accelerometer recently like this article - http://www.audioxpress.com/assets/upload/files/George%20NtanavarasAccelerometer.pdf Based on this experience, there are 2 features that would make this easier in REW 1) allow the user to specify the input sensitivity directly, e.g...

    Hi there, I'm just getting started with using REW and practised taking some readings using an AKG CK61 ULS Capsule (probably not great to measure) but just to get used to the process - I'm getting there. I now have a Behringer ECM8000 - So two quick questions; 1) I have downloaded the...

    I purchased an XMC-1 a while back. I recently got around to recalibrating my sub system using REW. Since my son has liberated my mixer with phantom power I can't use my Behringer mic. I decided to try the XMC-1 USB mic. It seemed to work swimmingly, but I have no idea how good/bad the...

    Hello, I would like to measure my loudspeakers (frequency response) but I face some difficulties. They are planar (dipole) loudspeakers so I expected some phase cancellation < 500 Hz but the freq. response looked too good to be true so I got suspicious. I did a new measurement with speakers...
