  1. My crazy bass trap design, with waterfalls!

    Home Audio Acoustics
    Hi everyone, first real post. I used REW to measure my bass traps, and picked up a few good construction tips from this site, so I figured I should make at least one post about how they went. So it's a variation on a limp mass absorbers, or membrane absorbers, whatever. The real difference in...
  2. Group Delay, Waterfalls & Spectrograms

    REW Forum
    In reviewing my Waterfalls and Spectrograms they clearly show the sub group delay that rises up to about 80+mS at 20Hz from zero at 80Hz. The Waterfalls have a flat top for this changing duration and the Spectrograph curves, both as would be expected. My question is that; while these graphs...

  4. Waterfalls, what to shoot for ?

    REW Forum
    I've read the 17+ pages on waterfalls, but I'm still not sure what result I should be trying to acheive. Is there a consensus view ? Without posting my waterfall plot, all frequencies are less than 300ms ~200ms except for around 20hz, where it looks like there is a little ringing. I remember...
  5. issues creating waterfalls and spectrals, Windows Vista

    REW Forum
    I upgraded to Vista since using REW last year, and reinstalled REW. I can take graphs and everything just fine. But I have issues when trying to do waterfalls and spectral charts. Say the measured response is 15-200Hz. The spectrals and waterfalls do the full range, but that full response is...
  6. War of the World's versus Bass I love you waterfalls

    DIY Subwoofers - General Discussion
    This one is for you Ryan. A few weeks back we had a conversation about that movie soundtrack. I thought that this would illustrate better what kind of sick bass is going on in the HT environment. This is a section of WOTW's where the highway gets blown up and it is the hottest bass section...
  7. Star Trek Bluray DolbyTrue spectrograms

    Movies | TV Shows | Hollywood
    Here are some direct to AVR of the low end from Star Trek Bluray B region, six-track Dolby stereo digital True, AVR is set at 0db. The screen captures have been taken with my Vivitar ViviCam 3785 from the CRT Panasonic there are artefacts due to way the camera sees the CRT image with over...
  8. Problem Graphing Waterfalls

    REW Forum
    I found a bug in how REW displays Waterfall plots . I am using REW V4.11 Build 1086. What I discovered is an error in the scaling of the waterfall data as shown in the following pictures. This first waterfall plot correctly shows a dip near 8.4kHz This waterfall plot was generated by simply...
  9. How do room modes show up on a waterfall plot?

    Home Audio Acoustics
    My room is 17 feet x 14 feet x 8 feet high. I used this page (http://www.bobgolds.com/Mode/RoomModes.htm) to get the theoretical room modes. I then put my subwoofer in the right front corner and my mic dead center of the three dimensional room space (ie 8.5 feet from the end, 7 feet from the...
  10. Waterfalls for "early reflection" investigation

    REW Forum
    Can REW do this? I wanted to generate a waterfall of the first 25ms (or so) and examine internal and early reflections of my full range speakers. But REW seems to limit me to a window length minimum of 50ms and a time span minimum of 200ms (!). Is there a reason why these limits exist versus...
  11. How to generate waterfalls?

    REW Forum
    Hello, I've seen numerous times people posting waterfall charts(?), as seen here for example. I guess the purpose of these is to analyze part of a source signal (like the ripped audio from a DVD) to show what frequencies are truely present in the recording (thus, for instance showing in theory...
  12. MF & HF Waterfalls

    REW Forum
    Hi to everybody, This is my first post. You excuse my English language bad use. Currently the LF waterfalls is truncated to 700 Hz MF & HF waterfalls, can be traced? thanks
  13. Waterfalls

    REW Forum
    I've read some posts lately that I haven't really agreed with. Point # 1 is regarding the effectiveness of equalization at low frequencies (15Hz-100Hz). The question posed is how can a parametric filter possibly correct room resonances. The assertion being that an EQ filter only lowers the...
