  2. Calibrated mic setup for sensitivity

    REW Forum
    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...
  3. Is there something wrong with my mic?

    SPL Meters | Mic's | Calibration | Sound Cards
    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...

    SPL Meters | Mic's | Calibration | Sound Cards

  7. Boom Mic Stand vs Other Types

    REW Forum
    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...

  9. Using REW to compare mic's

    REW Forum
    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...
  10. Using ReW with McIntosh Roomperfect Mic

    REW Forum
    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...

    SPL Meters | Mic's | Calibration | Sound Cards
    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...
  14. Phantom Powered Mic with HDMI?

    REW Forum
    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...

  19. REW using XMC-1 mic

    REW Forum
    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...
  20. mic measurement without audio output

    REW Forum
    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...
