    UMIK Measurement and Tuning

    Hello, I recently purchased a UMIK 1 to tune my car audio system and I am still learning the ropes with tuning and SQ analysis. I have ESB 3.165 doors and ESB 3K UMA units (Mids and Tweeters combined) installed powered by two Rockford Fosgate P400 4ch amps. All signals and crossovers are from...

    Stepped sine THD and N calculation

    Hello John, First of all thank you for making REW and all that it makes possible. I am currently using REW for distortion measurements of a DIY 100W power amplifier, with the usual idea to make it as quiet and distortion less as possible. Currently I am measuring around 0.00015% distortion...

    RTA vs Measurement difference

    Hi to all, sorry for the stupid question. I'm a newbie on REW, and I'm struggling to figure out where I'm going wrong. My setup is composed of a UMIK-II connected to a laptop, a miniDSP HD, and amplifier and a commercial speaker. I did several test to check how it works REW, and I noticed a...

    Save RTA data individually

    Please help me. I want to save these 16 data individually. If I press Cerrent, an error appears, such as a pop-up [An error has occurred]. 1. [Save inputs to independent measurements] is checked in [input Selection]. 2. Both Java and REW are up to date. Is there any way?

    Target Curve (House Curve) in RTA

    Hi, is there any way to display a target curve as known from the EQ module in the RTA module? Purpose is to do a live adjustment on the dsp and see the results vs the wanted target immediately. Many thanx Thomas

    Display Target House Curve in EQ or RTA Window?

    Hello, I am trying to tune a system (6 drivers with active crossovers and 30-band EQ) to match a house curve. It would seem that the easiest way to do this would be to display the Target Curve in the RTA window so I can see how actual Pink Noise compares to the the target curve, but I cannot...

    USE of REW RTA for engineering applications

    Hi all, I'm a mechanical engineer looking to do some acoustic analysis of a small device. I cant declare what it is that I am working on due to confidentiality, but I have a pretty solid analogy for it. Imagine a train conductors whistle, which has a cork ball in it to create that signature...

    How to set PC microphone level for spectrum analysis?

    I want to do some audio spectrum analysis on an appliance so I bought a Daytonaudio measurement USB microphone. I hope to use it with the REW to do the analysis. I plugged the USB microphone to my computer and tested the "RTA" and "measure" function in REW. I think they are working and it did...

    Apply desired smoothing to new RTA measurements in Overlays

    Hi! The above question was not an issue in earlier versions of REW. I am currently running the latest version 5,19 Beta 7, and every time i want to compare new measurements in Overlays i have to set desired smoothing manually. Maybe i have missed out on something? Here are my defaults:

    REW + UMIK-1 : RTA : erroneous low freq spectrum ?

    Newbie to this forum ... your enlighten is very much appreciated. Just got my UMIK-1, and I am not sure why I get so much unexpected spectral reading on low freq ( < 30 Hz ) ? The test the scenario, runs on a win10 desktop, with crappy speakers ( still betther than those on a laptop ) 1) Run...
