Hi Everyone. I'm brand new to the forum and hope someone can help me. I have a 2.2 channel Roon / HQ Player server-based system. The speaker configuration is two satellite speakers and two subwoofers - each with a dedicated DAC channel. I'm currently running 80hz filters in HQ Player between...

Does anyone knows how set the time reference to time align different speakers?

Hello, I read the REW manual and explored online, but I'm a bit confused in regards to what the "loopback timing" measurement actually does. Or maybe I'm not confused, I probably just overloaded my brain :) Could someone please let me know if my understanding is correct? 1. Without the...

Hello, My first measurement over *Use acoustic timing reference* with HDMI and ASIO4ALL makes problem or I do not understand something here. I have to measure here in Stereo without RIGHT speaker or direct LFE, in Stereo i have delay time from 100ms. What is OK, see the files thank you...

First post newbie here :wave: I am just getting started on measuring my system and at some stage I will want to align the timing on at least the L/C/R/SW's and will need to use a timing reference. My measurement setup is a UMIK1 mic for input and Behringer UCA222 for output. The left output is...

Hi I am new to this but I am keen to use. The setup I have is REW 5.19 beta running on Mac Sierra OSX. I have setup the soundcard to use the aggregate device on HDMI and the MIC is my UMIK-1. I was trying to setup a timing reference using acoustical but when I do the measurement there doesnt...

Both my mains and the sub are ported. I remember reading a while back that ported speakers disrupt relative timing between speakers and subs. Is this true and if so, can it be easily taken care of with external delays provided by a miniDSP or equivalent?

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 would like to do measurements using wav files playing though a DAC. The wav files I created with the generator does not seem to have a timing reference; the measurement never starts, it is waiting for the reference. Do I miss something? I am using miniDSP UMIK-1 USB Mic and running the...

I'm trying to use MSO and I realize that my measurements need a timing reference. UMIK-1 USB Microphone Win 7 Computer with latest drivers HDMI connection to AVR In the computer, I can set it to 7.1 and sent a test tone to each speaker in the system. However, when I go to REW Preferences, I...

John, Thanks for such a great product! Suggestion: The timing reference selection, Preferences > analysis > impulse response calculation > timing reference is not retained. It defaults to acoustic timing reference, which I never use, and I have to change it every time I start REW. Hopefully...

Hi please can someone point me in the right direction cant seem to find instructions? OS Windows XP Thanks in advance

Hello, I am new to REW and the forum. I installed V.5.17 B11 and was setting it up using my MacBook air speakers and my Berhinger ECM8000 connected to my IrigPro interface. The timing reference sound is heard when I run the measurement. When I connect to HDMI, the timing reference is not...

I currently have the latest beta of REW, but ever since the timing reference update, I can't measure 2 channels at once (via HDMI and ASIO). I have not selected use timing reference under preferences and when I select channel 1 and 2 for FL+FR+subs, I get output just from channel 1. The next...

I just downloaded REW's latest version...I have a Focusrite Clarrett 8PreX interface connected via Thunderbolt to my Macbook Pro. Avantone Mix tower powered speakers. Dayton EMM-6 (calibrated). I'm trying to figure out how to get a "System Delay" calculation made. I've imported the mic...

I've been trying to use a timing reference, but keep getting a frequency response plot that looks altered. I initially had lots more interference until I disconnected my amp from the XLR connection, but after figuring that part out, the freq plot looks decent, but is skewed only when using a...

I have been using loopback timing reference to measure speaker distances from the microphone tip (=listening position). I got realistic distances (calculated from the impulse response delay times) with my older soundcard M-Audio Fast Track Pro (Java), but the new Focusrite Scarlett 18i8 (ASIO)...

Hello, see my system and my room dimensions in my profile. I use Antimode to eq the sub. All measurements were taken with Antimode on. YPAO EQ the 5 channels only. Ypao filters was to flat. Distance from mains to MLCP= 2,70m; same from the center channel and the SW. Although YPAO set the same...

Hi all, I'm currently stuck at trying to get my drivers time aligned using REW. I have setup the system in the following manner: 1.) ECM8000 is connected to Steinberg UR22 preamp/audio interface on the right intup channel. 2.) Steinberg is connected via USB to the Mac Mini. 3.) Mac Mini is...
