EQ curve cloning with REW - how to??

[poddex]

Hello! Sorry for a wrong forum section for my thread if I make a mistake.
I have some non-standard question. Maybe it can sound weird, but...
For a years I have a software setup in my PC for listening a music. I create it more than 10 years ago from many experiments. It was a hard way, but I find a sound chain that plays for me over 10 years.
This setup is: Winamp + input plugin: MAD Plugin 0.15b + VST Izotope Ozone 7 (some settings there) + output plugin: AudioBurst PowerFX 2.10 from QOLabs + SRS Audio Essentials (virtual audiocard) 1.***. I use this setup (so call it Main Setup) for listening in headphones only - AKG K550.
Looks weird? Maybe, bit this setup brings me a lot of sound-opium for a years.
The problem is that I can't reproduce this system on Windows 10 x64! Thats because 2 of 3 main links in a chain - PowerFX and SRS Audio Essentials - doesn't work on it. SRS causes a BSOD with USB-soundcards (and it's discontinued), PowerFX doesn't work in player AIMP which I want switch to (because of their improved smart-playlists feature).
For now I use my Main Setup on a virtual machine Huh Every time I want to listen my sound-doping, I must start VmWare machine and listen through it. But I tired from this - after 3 years I tired so much.
I see that REW can record an EQ curve from audio output. I guess that all my DSP-chain finally produce ONE EQ qurve to audio output, so I can measure it and reproduce in Equalizer APO. Headphones are the same! Soundcard is the same. Only software has a difference. I think that AIMP mp3-decoder EQ differ from Winamp + MAD, but I even hasn't a base which I will move from. So I want to make a copy of my Main Setup sound curve (from Winamp on VM) and after that bring it to a Windows 10 setup.
So a question: how can I measure EQ in my situation and can I measure it at all? I see that people uses it for measure from a MIC, how can I measure for only cloning a curve from output and from specific player?
Please, any help will be welcomed! Need assistant, can't find, how make it myself.
Thanks for reading.

Thanks a lot, but I already see it. And I can't get an answer: how can I measure not from REW, but, using REW, capture EQ from specific player.
Can I do this or not? How can I get "currently played" EQ-curve?
Maybe I can obtain summary EQ virtually from soundcard currently playing some song, but how? I'm some newbie in sound tech

 

[John Mulcahy]

Use the procedure linked above. Connect a line output from the system to a line input to make the measurement. You don't play a song, you play the test signal.

And what it does for me? I want to measure sound curve from windows output with specific player played a song, not from REW. Maybe, I don't understand, so please, explain.
I see that CurveEQ and other software can capture live signal from DAW, how can I capture live signal from a player or windows sound chain?

 

[John Mulcahy]

It does exactly what you want. You say you want to know the EQ curve, which is the way your setup is changing signals (songs, test signals, whatever) you play through it. That is what measurement tells you, or would tell you if you were to try it.

Ok, if I think right - how can I obtain sweep or reference test mp3-sound for my player?

Measuring with File Playback.

 

[poddex]

I find Virtual Audio Cable (for avoiding analog signal via loopback out-in), but can't configure it for REW measurement trying again.

 

[poddex]

Ok. I made the setup with VAC and REW can measure output from VAC. Good.
I generated measure sweep via Generator. But I can't find the description of the process step-by-step. How can I open a window for offline measurement? I have VM with Winamp installed, and I can play generated WAV via Winamp, but how can I catch this output with REW, how can I open this window? Doesn't see this in a help, only screenshots, but not how open them

From the first lines of the help:

Making a Measurement

• Press the Measure button
  
  (or Ctrl+M) to bring up the Measurement dialog

Make sure you have the current version.

)) I opened it. I find a button Start Measure. It starts a Sweep sound. So, I measure what REW plays. But I need measure what Winamp on a virtual machine plays! Because of my plugins works in Winamp, not in REW. I need measure whole audio tract. How? I can't undertstand step-by-step and it seems to me that we speak on different topics. I don't need REW reproduce signal. I need REW to measure signal from a specific player by file genereted in REW. How can I load it or capture it in REW? Of course I have latest version.

 

[John Mulcahy]

Why didn't you follow the instructions in Measuring with File Playback? I don't know what else I can do, I keep pointing you to the instructions which explain exactly what to do and it seems you keep ignoring them.

 

[poddex]

I can't find what should do next I made sweep file. Then I saved it in wav. What should I do next? I can't find this (in attach)

 

[John Mulcahy]

Open the Measure dialog
Press the From file button
Load the sweep file in REW so it knows the file settings, either using the Browse button or dragging and dropping it onto the window that says "Drag the sweep file here or use the Browse button"
Press the Start button
Play the sweep file on your player

 

[poddex]

Where is this button?

 

[John Mulcahy]

When you said "Of course I have latest version" I guess you didn't bother following the link I posted to the latest version?

 

[poddex]

Ahhh, crap, sorry!!! Downloaded another link, my mistake. Will download right and try again......See it only now.

 

[poddex]

Thanks for your patience, John. Everything fell into place when I downloaded latest version.
I made a setup and get a sound, but I can't measure signal from VAC. I measured signal from virtual machine "Winamp+SRS", but I can't measure signal from "Winamp w/o SRS" - REW doesn't hear a timing reference. Also REW can't hear a timing reference from "clear AIMP". Maybe it's because a VAC latency, but exactly I don't know why. REW doesn't see timing reference sound and signal accept as noise.
So I will buy some cables and try to measure signal via traditional way - making a loopback from output to input.

 

[John Mulcahy]

The instructions are much easier to follow with the right REW version

Make sure you are measuring the channel which had the timing reference added to it when you generated the sweep file.

)))) you are the greatest with your last solve. But I can't understand exactly what helps me, your solve or maybe a cosmochaos)) I boot my OS againd and try to measure again...and REW measured!!! I can't understand, what I did, I changed nothing. So I still think that VAC latency or other VAC-related problem caused the issue.
Great thanks for help!
