    I am using a USB calibrated UMIK-1, a USB DAC and REW 5.20 Beta 12. I noticed that the IR plots phase inverts as the sweep length changes between 128K and 1M. Is this normal behavior ? If so, why would the polarity change based on the sweep length ? :huh: TIA

    I just upgraded my theater to a 7.2 speaker setup, from a 5.2 setup. The rear surrounds were added over the last week. It was expensive, after hiring my electrician to run the wires! Plus the purchase of new Klipsch speakers (which sound great!). But my T163 was previously programmed with the...

    Good day, I can't find an answer to the question how to deconvolve the exported impulse response using the sound card calibration in REW. From my experiments, it looks like by default REW doesn't do it. Here is what I tried: 1) Calibrated the sound card 2) Made a loopback measurement -- the FR...

    I have a saved measurement in which the Filtered IR frequency selection drop-down is greyed out, locked in a certain setting. Also, just loading that file starts keeping the CPU busy. The fix I found is to uncheck and recheck Zero Phase Filtering (in Filtered IR's Controls). Is this a known...

    Hello, I would like to perform a phase measurement at the LP. But I have some difficulties to interpret the IR response: 1st: There are 2 impulses quite similar within 1 ms. When I'm pressing "Estimate IR delay" sometimes the second is selected... So I don't know which one I should select in...

    I'm new to time-domain measurements and have a question, because most of the time I take things literally. But first, some background: It's no secret REW is able to use timing references in measurements to calculate system delays so that separate measurements have the same absolute timing...

    I'm trying to understand impulse charts and what they are telling me. I'm trying to integrate and time align 3 subs using REW that are connected to a MiniDSP 2x4 HD. (3 Rythmik F15HPs) Attached is the overlay graph for Impluse on the 3 subs. Config is 2 subs up front next to mains about 14 ft...

    Hi, Is it possible to inactivate the option "Set t=0 at IR Peak" to an imported Impulse Response? I want the first point of the IR at t=0, not the IR peak at t=0. Thank you for the help.

    I am experimenting with REW and what I will call Inverse Deconvolution IR Convolution Room Correction. I have a way to also limit too below any frequency (example: below 500hz). Would it be best to export measurement as just regular impulse, or minimum phase? Another way of asking, if one was...

    I am having a very difficult time finding a dimmer that is compatible with dimmable LED lighting and can be controlled via IR remote, so I can control them with my Harmony remote. I would think this would be easy to find, but I have not been able to find anything that does this for under $100...

    Would like to be able to import IR's from SysTune Pro, the problem is that in SysTune, the peak of the IR is aligned with time zero, and the full FFT length "circular". The end is the beginning is the end........like this So, zoomed in it looks like this: When I export the IR from SysTune...

    Hi guys, new to the forum. I just recently purchased a Panamax M5300 power conditioner with always on and switched outlets. I would like to take advantage of the switched outlets. There is one bank (switched outlets) dedicated to high current devices (receiver and subwoofer). I want to put...

    Hi Shackers, I imported IR wav files that I measured with another program (EASERA). My problem is that REW estimates what "comes" below and over the frequencies that are included in my IR files. E.g. I measured from 20Hz to 20kHz and saved the IR as .wav files. When I import them in REW it...

    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...

    I am working with the IR window and the Impulse graph, but I am not sure if my impulse graph should look like this. It is looking so messy. Also, I can't find out what the left and right windows mean and is there perhaps some advise or info available on what these different type of "algorithms"...

    Hello, I hope it is a quick question ... I am trying to make some measurement for my new mini-monitor that has Hypex AS2.100 (2 channels). When I get the IR exported file it covers between 1 and 2 seconds (~130K samples). In the Hypex software the IR graph space is limited to about 100 ms...

    I have a Denon AVR-1910 which the front IR receiver has stopped working. I'm attempting to utilize the "Remote In" jack on the back that's a 3.5mm plug, however I can't find an IR Extender or Emitter that transmits OUT to a 3.5mm jack. Any thoughts?

    Hi, Could anyone please advise if I should use the REW feature under the estimate IR delay tab that will shift the IR so the highest peak is aligned to time = zero, before I create my EQ filters? I am trying to create an IR EQ filter for some nearfield studio monitors. Am using one channel of...

    Hi all, I am trying to EQ some nearfield studio monitors via Cubase 7 recording software in my home studio. Cubase 7 comes with Reverence reverb that I can use to load IR EQ filters created via the REW export function. I am having difficulty getting the IR's created by REW give full width...

    Are there any products available that will allow me to hide my receiver yet still be able to use the original factory remote control. This is for a onkyo txnr818 thx!
