  1. Waterfall displaying as a rectangle no readable information

    REW Forum
    Hi guys thanks for having me, and hello everyone, I can't seem to generate a readable waterfall, i just get a big rectangle, its more than likely user error, I am on a mac running sierra (not high sierra) if anyone could tell me which settings to change that would be wonderful. Thanks Christian
  2. waterfall graph before and after initial room treatment - opinion request

    REW Forum
    Hello, I'm new to this forum in that I knew it since a long time (since I discovered REW through a GENELEC product specialist) but only now I began experimenting with acoustic treatment. I use a room in my house as a home recording studio, it's a rectangular room and it had a very bad acoustic...
  3. Waterfall vs Spectogram anomaly?

    REW Forum
    I don't understand why the waterfall is showing the decays well into 600ms but the spectogram shows no decays much past 400ms. Thanks
  4. Problems with Waterfall measurements

    REW Forum
    Is there anything that I could have messed up with my measurement equipment that would cause a very large decay time in the high frequency ranges? My waterfall 5k and above shows that sounds stay in the room forever and never go away. What could cause this? The purple was a previous...
  5. waterfall question

    Home Audio Acoustics
    I have built diy corner traps in both of the rear corners. Also across the top corner of the rear wall to ceiling. I have no other absorption in the room. Here is my waterfall. I am not sure how to read it or what steps to take next.
  6. Windows 10 and graphics corruption with waterfall

    REW Forum
    Has anyone experienced any issues with REW's interface becoming corrupted under windows 10? The application works fine, but it starts drawing in the wrong parts of each window if I open up the waterfall and hit generate or hit the DB meter. The other function seem to work properly, so those...
  7. Waterfall reading issue

    REW Forum
    Hi all, I had just applied some acoustic treatment to my room and was working into recalibrating and doing a new REW measurement. My first reading looked OK I believe. But I was playing with crossovers and speakers levels trying to learn / improve the graphic and then ... I broke something I...
  8. First Time REW results - Two nulls - any ideas?

    REW Forum
    I have completed my first REW tests. It looks to me that my major problems are the 2 nulls at 90 and 500 (with maybe a whole other bunch of problems) and the bass ringing <80 on the waterfall chart. I could be COMPLETELY off, so any feedback is welcomed. Any ideas? I know my gear is not that...
  9. 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...
  10. waterfall interpretation, cathedral ceiling

    REW Forum
    Thanks in advance to the folks who helped my out a few months ago. Wayne +1. I moved and I'm back to testing one of the rooms in which I hope to record classical guitar. It has a cathedral ceiling, sliding glass doors and plate glass windows and a rug. Understood it's not ideal, but it's where...
  11. Question on predicted waterfall decay chart

    REW Forum
    Is there a setting that may help to improve the accuracy of the predicted waterfall decay shown in the EQ window after REW creates filters? For instance after I do a measure I have almost no ringing. The waterfall shows that at 300ms there's some at 20 Hz and a little left at 30 Hz. By 450ms...
  12. Question about Waterfall graph first slice

    REW Forum
    Hi What is the meaning of the first slice of the waterfall graph, the one at 0.0 milliseconds? It shows the frequency response at this time but I can´t understand it well. This is the time where the first sound wave reaches the measurement microphone? It is the time when the first sound...
  13. Waterfall analysis in V5.1

    REW Forum
    Can anyone elaborate on this: "After V5.0 the waterfall behaviour has been enhanced to improve control over its appearance and extend its use to include the analysis of drive unit and cabinet resonances."- From REW V5.1 Help
  14. Waterfall Graphics Analysis Genelec 1031 vs KRK ERGO vs Trinnov MC²

    REW Forum
    Hi Folks, I measured Genelec 1031 Speakers with different sound optimizers/equalisers in a broadcast truck for a student projekt. Guess that might be interesting for many of you too ;-) Now I made Waterfall graphs and I think/hope I analyzed it right. There are quite big differences in the...
  15. Best Settings for Waterfall Graph

    REW Forum
    Hi, can you say me what are the best settings for the Waterfall Graph? A measure of my DBA with 4 Subwoofer. What are the best values for "Total slices", "Time Range", "Window", "Rise Time" ....... What do you say to the waterfall? I do not understand the long reverberation time at 33Hz ...
  16. Look At My Waterfall

    REW Forum
    What am I seeing in the 20hz range? Is that ringing? How can I fix this if it's a problem?
  17. Waterfall correct when using loopback?

    REW Forum
    I'm using JRiver and its loopback function and that enables me to measure the response with REW too. However, wil the waterfall (which is time based) be correct when doing this?
  18. 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...
  19. Waterfall graph from a RAM 1500 pickup truck

    REW Forum
    Long time lurker (almost 2 years with only 4 posts... 5 counting the post pad I needed...) I recently broke down and bought a new truck. It is a 2014 RAM 1500 with a "Premium" (cough, cough) Alpine sound system that really has the bottom end over-emphasized. Configuration of the system is 3...
  20. odd noises show in waterfall, spectrogram

    REW Forum
    Hi! First, let me say that I am a happy and experienced user of REW. I mostly use it with a MiniDSP 2x4 to room correct and provide EQ for Bose 901s, currently with a DIY subwoofer. I've come close to EQ-ing to my house curve (another concept I learnt here at HTS). What is odd is the past few...
