  1. Help With Interpreting Graphs and Next Steps

    REW Forum
    Hello, I was wondering if someone could help me with what I should be thinking about next. I have 5 filters on my preamp that I can use per channel which I use mostly on the low end. I'm trying to have the low end 8-10 dbs higher than the frequncies after 100hz, but I can't really pull that off...
  2. Interpreting REW output for optimal Sub placement

    REW Forum
    I hope this is the appropriate forum for this, and apologize if it is not. As I learn more about REW and sound in general I have been experimenting with the Subwoofer placement and trying to find the best positions. I have been relying on Audyssey but now wish to make sure my placement is as...
  3. Interpreting Impulse... Please Help!

    REW Forum
    Hi all, In my never-ending quest to interpret the impulse response of my dual subs (separately), I have run across another "bump" in the road. Below I have posted the response graphs for both subs, which I interpret to tell me that both have the same phase: both have the 100% peak in the...

  5. Help with interpreting REW graphs and general understanding of audio characteristics

    REW Forum
    Hi all, I'm new to all this, so please bear with me. (Have attached 2 x REW settings files for your reference.) I got a Mac with REW, Behringer ECM8000 and an Apogee One audio interface. I have done a measurement at my home studio and I did one for a restaurant where I recently did a sound...
  6. Interpreting REW Charts

    REW Forum
    Make some measurements using REW + X-Spectrum UMIK-1 mic this morning. Below are the charts that I tried to understand & self-interpreting. But the RT60/Waterfall/Spectrogram charts - I really don't understand that need some help. This chart: From 20Hz-200Hz, it seem that my room has some form...
  7. Modeling Help - Deciphering and Interpreting results

    DIY Subwoofers - General Discussion
    Long time listener, first time caller. I'm getting into modeling subwoofers for the first time. I have done a bit of research and might know enough to be dangerous (probably in a bad way). I'm detail oriented and want to understand why I'm doing what I'm doing. I'm a mechanical engineer...
  8. Seeking some input and help interpreting my REW results

    REW Forum
    Hello all, My name is Garth and I probably know just enough about REW to be dangerous. I’ve spent a good portion of the day generating ~25 frequency sweeps trying to optimize my new subwoofer integration with my main speakers for 2 channel audio. My sub is a Rythmik E15HP so many of the sweeps...
  9. Requesting Some Help Interpreting REW Graphs

    REW Forum
    Hi, I posted a different thread in which I posted a couple of graphs and received feedback that my graphs reflected that I clearly made a mistake in measurements. I followed the advice offered and I think I discovered a calibration error which led to some strange graphs. Now I believe I have...
  10. Waterfall Graphs - New to REW - Need Help Interpreting

    REW Forum
    Hi, Above are screenshots from a Measurement I took of my control room. I can't tell if I just don't know how to take measurements or if I just need help interpreting those measurements as reflected in particular in some waterfall graphs. The graphs above include one SPL measurement for...
  11. Interpreting First Results

    REW Forum
    Can anyone point me to a good read/tutorial on interpreting results. I just took my first measurements(.mdat attached). Im rather confused where to start. Any advice is appreciated. Thanks!
  12. Help interpreting results - dip at 70Hz

    REW Forum
    I am looking for some help interpreting these results before I apply any EQ. I am confused by the dip at 70Hz. Crossover is set at 80Hz. Is this normal? Green is sub only, red is sub and front speakers
  13. First REW Measurement... help needed interpreting results

    REW Forum
    So I finally got around to investigating my room acoustics, and it looks like I've got some issues from the start (as expected). Below is a plot of the frequency response measured with my HSU STF-2 subwoofer + Def Tech ProMonitor 1000 front speakers (left/right separately). Crossover for front...

  15. Interpreting Impedance: Manufacturer vs me

    DIY Speakers
    Hi all, First time post in this Forum, and need your brilliant advice: Some background: I'm building speakers and using REW for measurement of Driver in order to get T/S, Frequency response and impedance curves (to ultimately use crossover designer and Mathcad) to finalize my build. The...
  16. It Works! Now... Interpreting The Results?

    REW Forum
    Hi Gents, Thanks to your very kind help, I've now got REW up and running, and collecting measurements. However, I'm struggling to know what to do next, to improve sound quality. In my limited knowledge, I'm thinking that I need to do some minor EQing (such as a boost from 1.5Khz to 3khz)...
  17. Interpreting impulse responses

    REW Forum
    I have been attempting to understand these charts recently in an attempt to assess whether the channels in my system are adequately time aligned (and out of general curiosity). As such I have a few, quite basic, Q's about the data. I believe the charts I have so far contain some measurement...
  18. Problem interpreting UMIK-1 Calibration with REW

    SPL Meters | Mic's | Calibration | Sound Cards
    Hi I'm having difficulty interpreting the UMIK-1 calibration data and correctly measuring the signal from an acoustic calibrator using the REW SPL tool. Hardware: - UMIK-1 - Bruel & Kjaer 4230 Pistonphone (94 dB SPL, 1000Hz). I'm using the B&K 1/2" adapter. Software: REW version 5.01 Beta...
  19. Need help interpreting measurement

    REW Forum
    I've taken a measurement of my home studio (13'8" w x 15'1" d x 9' h) after applying treatment to my early reflection points (side walls and ceiling), along with bass traps in the front vertical corners (starting at the ceiling going down 4'). The purpose of the treatment was to clear up the...
  20. Help with interpreting frequency response measurements

    DIY Subwoofers - General Discussion
    I posted a variation of this in the BFD section but mostly would like to know there about how to equalize it. Here I would like to know how to interpret the response measurements for the subs. The subs are both DIY. One is a 15 inch sealed adire tempest in a 122l enclosure and the other is is...
