Magic = Audyssey One by OCA (Obsessive Compulsive Audiophile) + REW John Mulcahy's free and amazing Room EQ Wizard (REW)

ManCaveAudio · Mar 19, 2024

Great News for the users of Denon and Marantz who are using the Audyssey MultEQ Mobile app for room calibration.

Obsessive Compulsive Audiophile introduced "Audyssey One" which eliminates the complicated and tedious process of manual EQ to a simple "push this button" application for optimizing an Audyssey calibration with the help of REW. To proceed you required the MultEQ Editor mobile app and John Mulcahy's free and amazing Room EQ Wizard (REW).

This "Audyssey One" works for any configuration that the Audyssey MultEQ Editor App can measure and is covered from 2.1 to 9.1.6 including Auro-3D.

Below is the link for the YouTube video uploaded by the OCA and since upload he is responding to each one with their query.

https://youtube.com/watch?v=iU1ZBsru76M&si=pe41ERqXwOCQ2ZKU

Just keep in mind that you will get better results with max position measurements (8 positions and more) with the Audyssey MultEQ App. Better the calibration = Better the result. So ensure to get good measurements before processing.

Huge thanks to OCA for making this script and for constant improvement by introducing new versions of the Script (the Current version is Audyssey One v 1.1) and John Mulcahy's free and amazing Room EQ Wizard (REW) and making them available for free to all.

User's views, experiences and comments are invited to discuss on this.

With Regards,
Bhavik

What does this do exactly, looks like it's for the MultEQ Editor App, I have the MultEQ-X software

It works with ".Ady" file generated from Audyssey MultEQ Mobile App. You need to export your calibration ".Ady" file to the PC from your mobile App and import it to the Audyssey One where you will get the Zip File of all your 8 measurements you took while calibration through the mobile app.

Once you import these measurements in the REW and start optimization, it will automatically optimize and make necessary corrections and EQ, time alignments, SPL alignment etc within 1.5 minute and will give your new optimized ".Ady" file to import in to AVR through the Mobile App. It also works for multi subwoofer.

I did it, it took hardly 5 minute in all process and I could really hear and feel the differences between inbuilt Audyssey Cal vs Audyssey One.

You can give it try.

I just watched OCAs video the other night. While I've been running Dirac on my AV10 I plan to give this a go over the weekend!!!!!

Thanks, Please share your experience with all of us. Dirac vs Audyssey One..... waiting for your feedback.

I tried it with my AVR cannot say anything conclusive as I need to measure a bit more. This is my center channel

C0 is multieq measurements
C is REW measurements with Audyssey on in the same point (approx). Crossover is set at 150Hz rest looks very similar, I think I missed something.
I need will remeasure with factory reset to see if there will be any difference.

I found that latest multieq app is quite stable compared to the previous versions.

This is what I get in the MultiEQ correction window. It feels to me that Audyssey was not on during REW measurements.

This is a another one of those once in a while game changers! Completely amazed by its creation and so happy I'm aware of it.
Thank you @serko70

I do have the Audyssey App, not the X, I'm using Minidsp 2x4hd, is that part of the whole set-up??

No, because you need mobile app to export your calibration to your AVR through app. This Audyssey One gives you .ady file which requires mobile app.

You need $20 MultEQ mobile app. You can get help of any your friend who has mobile app and if it works for you, you can think to buy it.

MiniDSP 2x4 Hd can be used pre or post Audyssey calibration for better tuning your system.

Just tried OCA Audy One today, all went well after I figured out I needed the Beta version for my Mac.

A couple of questions/observations:

Audy One sets my LCR at the same distance even though the center is closest and Audy shows that.
Speaker trims are lower than Audy (1-2 dB)
The sub distance is 26.7' vs. Audy at 13.9' (sub is set 180˚ polarity to correct a dip.)

Running Denon X3800H so should be on speed of sound issue. Thoughts?

I used A1 as well, but didn't like the result at all, but I've used it as well as miniDSP to give me a much better result

Thanks, I have been working with Audy over a year and also Dirac since December and have not concluded that one is better than the other. I thought I would give Audy One a shot and see how it goes. Just tested with a few concert songs and it seems ok, will have to try on wider range of source material to see where it ends up. Just trying to understand what is right and wrong with it.

Just for curiosity, why do you have your crossover so high at 150?

This was my result after using A1

I don't, all are set at 80 by Audy One. Are you looking at the sub phase which can be 0 or 180˚ on my unit?

I have not got this far yet to check the work, just listening.

No, is just that you said that "Crossover is set at 150Hz" just curious, on mine A1 was set to 80hz, but the best I can get in my room is 110

Dr.OP · Apr 8, 2024

Gerry Iaria said:

I have crossovers set at 80-100hz. All 9 speakers are identical mtm layout with some closer to the wall leading to a slightl boost in the output.

Is there a way to automatically measure all 5.x.4 speakers? With a script or something?

Gerry Iaria · Apr 20, 2024

As anyone tried the latest version yet? I believe that there's a v1.3 and a v1.3x, I haven't tried them yet, my wife is traveling and she has the only laptop that we have

Yesterday I came to know the new manual A1 calibration method in AVSForum. I did it try and going to explain this experiment in five stages: Steps, Results, Challenges, Advantages, and Disadvantages.

1) Steps I followed:
As said by @ImageMaximum I set my AVR into pure mode. Audyssey Off, DEQ & DV off, Distances are set to Zero, Speaker levels set to Zero and speakers set as large (Full Range). I have 5.1 set-up as my secondary HT (where I leave on rent for my job. I have plenty of time to play around in the absence of family :greengrin:

). (AVR is Denon X4700H, going to install Marantz Cinema 70s which is in transit and X4700H will move to the main bedroom theatre at home in 5.1.4 set-up)

I took 8 measurements for each position (full range 0 to 20000) with 1M sweep. Save that file as .mdat. Export all measurements impulse as text (please untick Normalise sample to peak value). Remove all frequency responses from REW and import the impulse response you exported. Change the name of all measurements (C0,C1, FL0,FL1, etc.). Go to All SPL, select all, right-click the on first measurement, Click on Change Selection Cal, and Import your Calibration Mic Cal File in Mic/Meter Calibration. You can align SPL of all measurements to avoid any SPL offset while optimization.

The next step is to open A1 in editor mode and change the Max Gain Value from 0 to 3,6,8 as per your like (I use 8 because this helps me to measure my sub flat down to 31HZ, without that it measured flat down to 45HZ), Change the upper limit to 20000 from 200 by default, replace the offset value -42 to 0 and save A1 file. (These are the modifications I made before running optimization which are not necessary to do if you do not want to alter OCA's settings. This was an experiment for me to learn the best possibilities to get better sound with the help of A1)

Now run your A1 as normal. Import your .ady file, but ignore the exported zip file extracted from A1 (please ensure your impulse responses are there in REW and all basic settings are done for A1 as suggested by OCA). Click optimization.
Your new .ady file is ready to upload. Enjoy your new sound.

2)Results:
The results are quite surprising. Frequencies are much flatter than the native A1 process done with .ady file. Got a much flatter response and sounds better than the native A1.

Post A1 optimisation I only EQed my Elac 3010 Sub with inbuilt 8-band PEQ. Thanks to Elac for 8-band PEQ

Below is the final results (LFE, FL, FR & C speakers) post optimization. You can see a big peak or bump between 1 and 2 khz which is never there. Can anyone help to understand the reason behind it?

The main .mdat file is attached herewith (https://drive.google.com/file/d/1SrfMz4Zl4yQCFOHrf-5CvdoeJEkzzR0Q/view?usp=drivesdk) for review and help on this bump observed in FL & C speaker between 1 to 2 khz. It would be great if someone could help with this.

My FL & FR (Wharfedale Dimond 212) speakers are not measured well from 1KHZ (specifically FL). you can see in the below graph. A1 never recovered or made it flat (But Aydyssey calibration from the Mobile Editor App. Aydyssey MultEQ-X or Calibration through AVR can recover it/make it flat). I am going to replace it with a Dynavoice DM6 bookshelf speaker (used one).

Measurements are separated for better illustrations.

Same calibrations without separation:

3) Challenges:

This process takes more time than basic A1 optimisation (but finds to be worth it).
I forgot to untick the Normalise sample to peak value while exporting the impulse responses which was giving me very odd optimisation results. Two times ran optimisation then I realised the mistake I made.
Unexpected bump is observed in my FL & C speaker between 1 to 2 KHZ which was not there.

Other than this, no other challenges I faced.

4) Advantages:

The main advantage of this method is you have full control over your measurements. At any point in time, you can add a new position, replace any measurement with an old one, remove a position, Increase measurement numbers or decrease it, if you replace speakers, you just need to replace the old speaker's measurements with a newer one.
You can get high-resolution measurements like 1M, 2M, 3M etc....
You can do SPL alignment before optimisation
Can compare before and after results
A calibrated microphone can be used for measurements
No need to worry about Audyssey Mobile Editor App Version. (read many discussions around this in this and other traces whether it is 1.7.2 or newer version. I do not think it is important with this method. Please make me correct on this as I could not understand the error people talking about).

5) Disadvantages: For me, I must EQ my sub post optimisation (even after Audyssey of A1 calibration) other than this I haven't seen any disadvantages in comparison to the native A1 optimisation process.

Inputs/suggestions on this are welcome to correct any mistake I made in this process.

This was a warm-up for me before the new AVR and Speakers going to be installed.

This is quite long but I hope this will help others to experiment with their system.....

That must have taken you a while to do, I got lost after the first few lines but I've tried A1 1.1 and 1.3, but didn't not like the result, I think I'll stick to REW -Minidsp

ManCaveAudio · May 15, 2024

This is the same REW + MiniDSP. You do not need to run Audyssey. Audyssey is only use to import this manual calibration in to AVR. This is manual process but only automated. If you don't like Dr. Toole curve used by OCA, you can replace it with Harman curve. Just need to alter A1 codes.
