    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...

    Just got new umik from csl. After REW sees it and I point it to the first 0deg file supplied with the usb sick, REW puts up a mssg box that says it doesn’t contain a cal file. I’ve emailed csl but I figured I’d ask y’all while waiting for a response. Thx! Btw...have y’all done a measurement...

    Hi there, I'm just getting started with using REW and practised taking some readings using an AKG CK61 ULS Capsule (probably not great to measure) but just to get used to the process - I'm getting there. I now have a Behringer ECM8000 - So two quick questions; 1) I have downloaded the...

    When taking a RTA measurement in REW you have the choice of taking spectrum measurements (power/hz) or various fractional octave measurements (ie 1/12 RTA). It is impossible to ever compare the graphs of the two due to the different units, though it is mathematically possible to convert at least...

    So I'm venturing into a REW & Umik to measure my sub. Is it worth the extra few dollars to buy a UMIK from cross spectrum (as opposed to one from mini dsp)? What are the advantages? Thanks!

    I bought two EMM-6 microphone which were recalibrated by CSL. Can Exact calibration be the proper choice for the alternative to the expensive one?

    I tried to order a Calibrated MiniDSP UMIK-1 microphone from Cross Spectrum today. At the bottom of the page it says they usually ship in 5 days, but when I try to complete the order it tells me they are out of stock. Does anyone know if there is a way to get on a waiting list? Is there...

    Hi All, I'm a new REW user so this may be a basic question! I have a calibrated Dayton EMM6 mic with a datasheet from Cross Spectrum labs. I have used the FRD file that they supplied to give REW a relative response of the mic. I was wondering if the supplied data for my mic is sufficient to...

    Hello, i am a new user for REW. I just need to know why I am having a big difference in dB level between the 1/1 octave option and spectrum option despite of choosing the option within one environment. as you can see thru the graphs attached, when I choose the spectrum option of RTA, the...

    I'm curious if anyone has discovered any specifications or specifics regarding the Media Player (ver 11) "Bars and Waves - Bars" spectrum display? I'm interested in getting a estimated amplitude measurement (in db) or number of frequency bins for music or signal playing. Are there any hidden...

    Hi There I apologize ahead of time for starting this thread if this question's been answered before but I couldn't find it. I'm about to buy a calibrated Dayton EMM-6 microphone from Cross Spectrum and I'm looking at either the Basic Plus version or the the Premium Plus varieties. The non...

    I’m interested in speaker design and construction. One of the design decisions that must be made is determining the power rating of each driver in a multi-driver system. Anybody know if there is an available study that shows the typical relative power contained in each segment (1/2 octave, 1/3...

    Hello. When I export a 1/3 octave Spectrum measurement I've taken, and export the graph as a .txt file, I get thousands of data points, rather than the 1/3 octave frequency centers I've chosen for the graph display. Is there a way to export the data but just have the file show the levels at the...

    Using REW and looking at the crossover can be complex. Espicially when looking at mulitple crossover sources such a CD player, receiver, pre/pro, external crossover. Which one do we use and how do we look at it under a microscope? First you need to hook up your source to the input of your...
