  1. REW Forum
    So I received a miniDSP UMIK-1 for Christmas and wanted to take some measurements in my home theater room. I read through the long manual for REW and I have to admit that about 95% went way over my head. No big deal, I figure I start easy and basic. I should probably explain my setup. It's a...

    Hi, I've been using Rew for a couple of years, so I do know the basics. I have an old laptop running XP that I use to take room and frequency measurements. I've never been able to make it take an impedance measurement though, so I've always used my desktop for this. I use a homemade jig and it's...

    A friend just picked up a Klipsch KW-120-THX woofer for a steal. Unfortunately TS parameterss for this woofer haven't been easy to come by on the net. I can't seem to find box dimensions either. Do any of you guys have any of this info or know of someone in the DC area with a test rig to...

    The AES journal has a very interesting (and lengthy) article this month by Floyd Toole on measuring and calibrating many kinds of audio system, worth a read - it should be free to download without registration or payment: The measurement and calibration of sound reproducing systems

    Hi, I'm new to this forum and room equalization. So a "Hello" to all! ;) My first question is which microphone type to use? The pre-amp is a Behringer Firepower FCA610 USB-Audio interface with two TRS/XLR microphone inputs (+48V phantom power) connected to an Ubuntu 15.04 (Linux) machine. On...

    When I'm trying to calibrate I get the below odd results. I'm using a USB M-Audio Mobile Pre with a 100ohm 0.1% resistor in a jig I recently put together. I've got the headphone output running through the jig in the calibration setting to the M-Audio 3.5mm input. I have to turn the input down...

    Hello everyone, I was hoping somebody might be able to shed some light on this topic. I am a custom car audio installer by trade, over the past couple years I have found a way to make my job exciting and "new" again. REW has played a significant roll in this newfound excitement. I've discovered...
  15. REW Forum
    I've been using REW for some time now, and I noticed something about how it works which I wanted to ask the forum about. Specifically, the question has to do with measurement sweeps and the range we set. I noticed that when I set a range for a measurement sweep, the results at the start...

    Does anyone know where I can find the calibration file for the Behringer ECM8000 measurement microphone so I can get an accurate as possible reading of my room in room eq wizard?
  19. REW Forum
    Something I don't quite understand is why I'm getting such significantly different measurment result with the different sweep length, I expected these to be similair. I thought it might have had something to do with the impulse time due to room accoustics, so I shortend this but with little...
