  1. Viewing saved peak data from RTA spectrum

    REW Forum
    I have saved RTA spectrum views with the SAVE button, and then these are saved in an *.mdat file, but I haven't worked out how to view this saved "peak data" again in the RTA, if indeed I can. There is a hint on p.158 of the PDF V5.19 HELP file "The saved measurements can be used as references...
  2. Date stamp on saved graph from RTA

    REW Forum
    Hi, I haven't been able to discover what controls the creation of the date and time stamp on the saved graph of the RTA. When I save a spectrum measurement as a JPEG I have sometimes had the date and time added, but recently the box is greyed out and I just see "no measurement". I'm running REW...
  3. Help with REW RTA measurement on generated sweep

    REW Forum
    Hello, This is my first post here and first stab at REW after lots of reading and video watching. I wanted to share what I did as a workflow and the graph I got so that someone can help me further as the results do not make sense to me. 1. Installed REW 5.19 with java 2. Connected my miniDSP...
  4. real time phase via RTA

    REW Forum
    Hello, My name is Andy, I am new to the forum. Thanks For having me!:smile: A while back I was using rew and setting up loop-backs and such. Just playing around and exploring features. Somehow I was on RTA and saw a phase check box and I checked it and I saw the Phase along with the frequency...
  5. Feature Request: Calculate distortion only on graph limits (RTA)

    REW Forum
    If possible, a checkbox to calculate the distortion only on the visible area of the RTA graph would be excellent. Often measuring at higher frequency rates makes it much quicker, but there's often a rise in noise above 24 or 48khz. An option to limit the distortion, THD and THD+N calculations...
  6. Difference trace in the RTA

    REW Forum
    I may have just missed the button. Is it possible to get the live difference between the reference and the mic feed on the RTA?
  7. RTA Phantom noise floor or setup issues??

    REW Forum
    Please bear with me...very noob thread. Trying to use REW for a car audio application. Got the UMIK-1 mic and calibration file. I am really thrown off by inexplicable noise floor measurments taken with the mic on it's tri-pod, in the house with nothing else on (silent as possible)?? I've gone...
  8. RTA mathematics

    REW Forum
    Dear all, Could anyone here explain to me (or point me to other sources) on the mathematics behind processing the frequency spectrum into the RTA plots as REW does? Also how is the dB(Z) value calculated? I have tried taking rms averages of both the RTA (1/48) data and the RTA at each integer...
  9. REW 5.1 Snapshot export font issue in RTA

    REW Forum
    If I use the camera icon to export the RTA screen to an image, the box in the upper left which indicates the levels of each harmonic and overall THD is unreadable. If I do a screen capture it looks fine, but I cannot overlay a title on the plot..!
  10. REW RTA - must be doing something wrong

    REW Forum
    So, I'm trying to take some simple RTA measurements using a Dayton Umm6, their provided calibration file, and uncorrelated (stereo) pink noise. My measurements are coming up with more slant than my ears hear. Comparing it to my housecurve you'd think it was super bass heavy (+30db above vocals)...
  11. Plotting multiple inputs on RTA

    REW Forum
    Is it possible to at least run two instances of REW with preferences set to different inputs, so that I can see 2 RTA graphs at the same time? Preferably to have functionality from 'All SPL' view in RTA. My usecase is a dance studio, where I assume the response should change a lot when it gets...
  12. RTA - Frequencies below 15.75 Hz

    REW Forum
    The Spectrum and RTA graphs in the RTA Window don't show any data below ~15.75 Hz. Is it possible for this to be extended lower with a few more octaves? Here is why I am asking: I'm able to route movies directly through REW using my MOTU 1248 AVB mixing panel. I used an 80 hz crossover with a...
  13. The RTA debate......

    Mobile Audio
    Hello all, my name is Nick, I am a professional car audio installer of 15+ yrs. I have been trying to find a forum with other professionals or advanced DIYers, is there anyone here who either uses REW or any other type of dual channel FFT analysis system for car audio system optimization, or...
  14. REW, umik-1 1000hz peak in SPL and RTA?

    REW Forum
    Hi i hope you can help me with this, I installed REW and chose the calibration file, everything seems fine, but, when i open the spl meter, it shows a level of 65db. When i open the RTA spectrum analyser, it shows a peak at 1000hz and a minor one at 2000 hz. what causes this, and how do I get...
  15. Feature request: RTA view of IR (ETC)

    REW Forum
    I have a proposal for your consideration: It would have been very convenient if REW could contain a real-time view of the impulse response, e.g. the envelope (ETC). My usage is when working on placing absorbers and diffusors in a listening room, I use the IR ETC envelope to identify...
  16. Using RTA To Get A Curve

    REW Forum
    So I got some new subs last week today I decided to try and get a nice sounding curve using the RTA feature instead of the measuring and adjusting back and forth way. I prolly need some practice but remember something Wayne said about using broad filters and as few as possible. Well i am using 3...
  17. RTA Results Help

    REW Forum
    Simple 2-channel system. Room 28.5 feel X 13 feet x 7 feet. At my listening position the RTA looks like this. Any suggestions has to how to bring up the frequency response above 2kHz or pull down the rest of the frequencies? I'm using no room treatments at this time and do not wish to insert...
  18. Monitor RTA with 1/3 Smoothing?

    REW Forum
    Is this possible? It sure would be great for actively monitoring the effect of eq mods.
  19. Live sound RTA help.

    REW Forum
    Hi guys, I know a bit to get around in live sound & need help in doing RTA for a system in a small hall. I'm using an M-Audio Fast Track interface with a Behringer ECM 8000 measurement microphone & RTA program from a laptop to generate pink noice. Basically from what I understand & read is the...
  20. RTA Mic Placement?

    Mobile Audio
    Thus far I've been using my UMIK-1 pointed strait up, along with a 90deg calibration. In this setup, my tweeters(dash) are probably 30degrees below the 90degree mic-plane, and my woofers are maybe 45 degrees below the 90degree mic-plane. By "mic plane" I mean the plane that is perpendicular to...
