rew

Hi, how can I put two graphs in REW and visualize only the difference between them. For example: Graph 1 has +15dB at 5kHz, Graph 2 has +10dB at 5kHz, the difference should display +5dB at 5kHz. Thanks in advance! :)

Hi again ASR community. Some time ago you helped me a lot in this thread Since then I have changed my audio setup and now it is KEF R3 with Lyngdorf TDAI-3400 streaming amp. Below please find the measurements I did using REW and UMIK-1 mic with RoomPerfect enabled (Lyngdorf room correction...

I currently have the XLR output of the Gustard DAC going to a Buckeye amp and it works well. The way I integrated the sub is with high level (speaker wires) since I don't have a receiver with LFE output and DSP room correction and speaker volume adjustments. I have the sub crossover dialed in...

The other day I mentioned elsewhere this wonderful video by @OCA. It covers many topics but it has one little trick that is so genius that I think it deserves its own thread. In short it is to make Audyssey believe that there is nothing to correct about your speakers and your room. This turns...

Dear All, I've bought a MiniDSP nanodigi, 2 8" subwoofers and a UMIK-1 and I've been experimenting with them for 20+ hours now. For my latest configuration, I have done the following: 1. REW sweep measurements in bass region for each of the 4 drivers for 3 LPs, I used acoustic reference on the...

I am sharing my REW measurements seeking for conclusions, thoughts, EQ and/or room treatment advise. What you see are the measurements of my main(2,2m) as well as my secondary(5m) listening position in a 30m2 non treated but really cared(curtains, carpets, furniture, canvas, positioning) room...

Currently my SMSL SU-10 DAC is also the preamp for my Audiophonics HPA S400ET poweramp via balanced connection. Powered sub is KEF KC62, fed by unbalanced output from SMSL. My room has a floor to ceiling glass wall & patio doors to entire left side. WAF precludes most acoustic treatment. Looking...

Hello everyone. Today I did a little experiment: I downloaded the Harman 2018 over ear target curve from AutoEQ repository and also the headphones measurement available there. I then used REW to equalize the headphones to the downloaded Harman target curve and, unexpectedly, the result doesn't...

I was wondering if one could flatten out a microphone by inverting the frequency response found in a graph. I would like to get a taste of the result without having to buy an expensive microphone for this... There's a Superlux microphone, which is pretty cheap, but requires an audio interface...

Hi all, So I set myself up today to re-calibrate my system which I was looking forward to but have had problems with REW not seeing my DAC's digital interface? I use an RME ADI2 PRO fs be and am connected to my laptop via a USB cable yet REW only sees the analogue 1+2 interface? Can anyone shed...

Room is almost a square (9x11 feet), with one side being a long doorway opening, to a larger room, therefore no right wall really. Right wall 5.5 feet away from Mic, with 3 windows. Mic is almost positioned in the middle of the room. There is pretty much no left wall as you can see. All graphs...

Hello! We have a PC connected to the TV in the living room which we use for streaming and music listening. Using a combination of measurement mic, REW and EQ APO I was able to bring the room FR to the following level. What I don't know is whether this is good enough or not or should I continue...

Were can i learn how to read frequency responses and what they mean? ..i have been using REW for a year now and there is still lots of questions i have. I am currently installing a full car audio build for SQ and i have everything but not the understanding. I tried reading rew how to guide but...

Hello Guy's, I just recently finished my "DIY" Theater Room and overall I am very happy with the result... :)... Admittedly I am very new to all this but doing research, planning, and implementation is what I love to do... Here is my setup...I am looking for ideas to further improve this room...

The most budget audio streamer option is an HDMI streaming stick. The cheapest of them fluctuates around $30. However, there is a problem. All known HDMI sticks upsample everything to 48kHz. Yes, connecting USB DAC to some of them is possible, but it complicates things and increases the price...

When generating sine tones in REW, exporting as WAV, then analyzing in both Audition and REW, the results are identical: However, when I generate and export the tone in Audition, then run the FFT with both programs, it looks like this: Where do these spurious tones come from? Here's the 1k...

Can you please inspect my measurement? It is an untreated 4000cubic ft office room . Edifier Mr4 + Temblor T8 sub https://www.dropbox.com/s/ikystyc963dq5oh/MR4%2BT8SUB.mdat?dl=0

Hey guys, I've spent a lot of time Optimizing my Speaker Positioning using REW and after weeks of tweaking my current set-up has the following psychoacoustically smoothed frequency response at the listening position as measured by a Umik-1 microphone: As you can see I've got a...

Hi clever nerds :) In a continuos search for better sound, I wonder how to interpret the phase diagram in REW. Can you tell me how a correct phase should look like? This is a recording from my room from en experiment. I used the in-line RCA crossover (built in) fixed 80 Hz 12dB/oct. in my...

Hey all, In another thread, y'all might be convincing me to invest in a minidsp UMIK-1 measurement microphone. I'm thinking about one advantage of a USB mic: portability. Could a smartphone use the UMIK-1 and its calibration profile? If so: Is there a recommended app for iOS/Android that's...
