  1. Using IPhone to test spl

    REW Forum
    I am an absolute novice but have enjoyed reading many of the posts on the forums over time. I have recently acquired a BFD (1124) but at this time do not have a mike. Given the number of apps available for the iPhone that measure sound pressure levels can I use these as a starting point to try...
  2. REW SPL Data Logger to Cal AVR Speaker Levels

    REW Forum
    Well, I’m deep in the process of trying to integrate 2 different subwoofers with an existing 7.2 home theater system using a miniDSP 2x4 DSP for the subs. However, that’s not what this post is about. During this process I decided to do baseline measurements of the existing speaker settings...

  4. High spl measurements

    REW Forum
    I am trying to take some measurements of the maximum SPL output of my subwoofer. Problem is REW always shows clipping when setting amp gain anywhere near high power. Is there a method that will allow REW to tell me the max SPL output somewhat accurately?

  6. ALL SPL Graph (and other windows) suggestion

    REW Forum
    I'm working with multiple windows and it occurred to me that it would be handy to have a key command for 'Unselect All' or 'View Only' so that a user doesn't have to unclick (in my case) 14 windows in order to view just the one i'm interested in at the moment. It may already exist but I...
  7. Realtime logging of SPL?

    REW Forum
    A few years ago, I know that REW did not have the capability to log SPL information in real time (say 1S intervals) directly to a text file. Does anyone know if that feature has been added? Would be really really useful for me. Thanks!
  8. UMIK-1 SPL Calibration

    REW Forum
    Hi, I bought the Mini DSP UMIK-1 microphone and when comparing the SPL meter in REW to the classic radio shack SPL meter, the REW measurement is 5db hotter. I have the correct calibration file loaded for the microphone, could it be something else? Thanks, Sean.

    REW Forum
    So I successfully attached a UMIK-1 mic, downloaded the calibration file and the latest beta of REW 5.17 beta 14. I set the mic to unity gain in the audio midi devices and to 48khz input. Since I am a stereo listener I just have two speakers - about 10 feet apart toed in to point to the...
  14. SPL not working

    REW Forum
    OK, I use the REW every few weeks and last time I used it about 2 weeks ago my mic and SPL sound pressure meter worked just fine. But now I can't get it to work. I use a UMIK-1 mic and it shows in preferences that is what I picked. I even tried to use the internal computer mic and it still won't...

  17. Detailed Instructions for SPL Calibration

    REW Forum
    I've been using REW for some time now, and feel like I have a good grasp on things. However, sometimes we often find ourselves moving quickly over some of the basics and then later questioning our techniques. I'm wondering about something like that today. Topic: Calibrating the SPL with a...

    REW Forum
    Dear Forum, I am currently seeking to use REW primarily as a recording SPL (for recording aircraft noise, which is by the way preventing me to enjoy an audiophile life anyway). I would like to use the miniDSP USB Measurement microphone UMIK-1 together with the SPL functionality of REW in a...
