  1. Variable smoothing: really 1/48 oct below 100 Hz?

    REW Forum
    In connection with an earlier thread about smoothing, I was doing some experiments with REW. I took a single unsmoothed measurement and saved it twice under two different names, then using File, Open Measurement, I brought these two identical measurements into an empty project. Then I...
  2. REW V5.17 Beta 10 smoothing bug

    REW Forum
    Hi John, The smoothing controls are no longer working properly in REW V5.17 Beta 10. - "Remove Smoothing" doesn't work, while "1/48 & 1/24" give the same "look" ( & that "look" seems to be some variation of smoothing values derived from between 1/12 > 1/24 ). I can't say how long this problem...
  3. Smoothing between 1/48 and none not working on REW v5.1 OSX 10.10.5

    REW Forum
    Is anyone else experience this issue? When I'm running sweeps, all of my measurements are defaulting to 1/48 smoothing even though I have no smoothing selected in the analysis preferences. What's strange is, I ran sweeps a few weeks ago and it didn't do this so I don't know if there's something...
  4. Smoothing drop down menu tickmark

    REW Forum
    Would it be possible to have a smoothing indication tickmark in the Graph drop down menu? You can see this information on graph legend but when choosing smoothing this is unconviently quite far away. Even two different smoothings could be chosen for comparison! I use this quit a lot by opening...
  5. best type of smoothing for EQ

    REW Forum
    Good morning, I make EQ filters with REW and use it with EqAPO only to improve room correction in my small (12m2) home cinema room Before the version 5.12, I used 1/12 smoothing and made a set of filters for each of my 5.1 in 20-2000hz ( 20-200 for sub) range With 5.12 and now 5.13 , I see...
  6. Variable Smoothing

    REW Forum
    How does it work? I've only played with it briefly, but it looks like 1/24 octave at lf to 1/6 or 1/3 octave at hf.....
  7. Fractional octave smoothing

    REW Forum
    How fractional octave (e.g. 1/12) smoothing is done in REW? Is it by a Butterworth filter or brick wall filter?
  8. Monitor RTA with 1/3 Smoothing?

    REW Forum
    Is this possible? It sure would be great for actively monitoring the effect of eq mods.
  9. Analyzing different smoothing graphs

    REW Forum
    I have recently started with REW and before I make any changes to the room and speakers, I am still new to this and would like some interpretation from these graphs, mainly from the graph with no smoothing and how it compares to the other graphs. The added detail at the higher frequencies with...
  10. First measurement, which smoothing to use

    REW Forum
    I want to make sure I have everything setup correctly, not sure what smoothing to use. Also do I need to adjust the room size or mic distance from speakers? Here's my first measurement using 1/3 smoothing. When I calibrated my soundcard, I had the laptop volume at around 35%, however when...
  11. Recommended smoothing setting for generating filters?

    REW Forum
    Is there a recommended smoothing to apply to the measurement curve prior to generating room correction filters? For example, 1/48 smoothing can produce filters that have very sharp peaks and nulls - which, when applied in practice, may actually cause new problems in room response. So, is there...
  12. REW Beta 9 ETC Smoothing Bug

    REW Forum
    John, I've tried to alter the value in the ETC smoothing white box with no success. It remains at 0ms. Thanks, Harry
  13. Which smoothing filter to use in measurement

    REW Forum
    I have been using 1/48 smoothing filter in my Preferences. Should I use another smoothing filter like 1/6 instead ? What is the impact on using 1/6 vs 1/48 besides smoothing out the measured curve ? Tks
  14. Problem with smoothing option

    REW Forum
    Hello everybody, I'm a newbie... I'm trying to use RoomEQ and I done my first measurement. My problem is that when I try to apply 1/3 octave smoothing, the red line in All SPL section disappear. I can see it only with no smoothing. I can't find anything about this in the forum. Any...
  15. what smoothing should I use for subwoofer frequency response

    REW Forum
    I use 10hz to 200hz signal to find subwoofer frequency response. I choose length to be 1M and sweeps to be 4. Is it enough? The result SPL frequency response is defaulted to be 1/48 octave smoothing. If I choose 1/3 the cuvre will be much flat. I'm wondering which octave smoothing should I look...
  16. dumb smoothing question

    REW Forum
    So, just curious...when looking at room response, do people tend to look at the smoothed response or the raw data? And, if looking at smoothed, what level and why? (I've been mainly looking at 1/3 smoothing - but I had no reason to choose that...) Thanks, Mark
  17. Smoothing function in new REW version?

    REW Forum
    so... in the minimal filtering/hard knee house curve thread there was talk about in a later version of REW there may be functionality to smooth the response curve rather than just the waterfall (use + and - gain on the automatic eq); is this possible yet? EDIT: I have a Crown USM-810 (ok...

    REW Forum
    Where do I find the 1/3 smoothing tab? Tommy D
  19. Waterfall with >1/24-octave Smoothing

    REW Forum
    Hi, FP for me! Fairly new to REW, but not new to speaker measurements (own TacT RCS 2.2XP). Quick question: possibly I'm being an idiot, but is there a way to specify >1/24-octave smoothing during waterfall generation? I'm using the waterfall plot for 400Hz-30kHz as a proxy for cumulative...
  20. Bass Limited Smoothing Question

    REW Forum
    Hi all, Lat night I discovered that the tweeter dome on one of my mains had a small dent in the center (I have no idea when it happened, either... I know I inspected them when I got them... oh, well). A little research tells me that the effect on the sound will depend on if the dent deforms the...
