Dirac Live with Volume Dependent Loudness Compensation
GET EXTRA 10% OFF WITH CODE #SIMPLE – LEARN HOW
Includes Dirac Live Curve Editor Excel Tool used to implement Loudness Compensation & Dirac Live Loudness Memories Excel Tool used as a cheat sheet!
Dirac Live is great – no – amazing, when set up correctly. But – and this is a huge but – it doesn’t have loudness compensation built in. This means you need to mess around with so called “house curves” and you aren’t quite sure if you are getting the correct tonality as the content was meant to be heard.
- Are you confused about what “house curve” to use?
- Have you been messing around with Dirac Live target curves for just to get it to sound right and it still isn’t quite there?
- Do some curves work great for one content but sound totally rubbish for others?
If you want to LISTEN TO CONTENT AS THE CONTENT CREATORS INTENDED, then this guide is for you…

What is in the Guide?
(See Table of Contents below and Change Log)
I reveal the secrets to getting amazing results with Dirac Live including:
- The 5 Pillars of Reference Playback (new in v2.0) – an overview map with detailed diagrams for each 5 major areas to serve as a map for the guide.
- How to set up your speakers and your room for optimum results to ensure Dirac Live is spending processing on polishing up the sound, NOT correcting setup issues.
- How to integrate single and multiple subwoofers with Dirac Live
- The Dos and Don’t of Dirac Setup
- 5 Microphone patterns in addition to what is available with Dirac Live (new in v1.0)
- Tight, Medium and 2 wide patterns
- On restricted pattern used for troubleshooting bass issues
- Emulate Audyssey Dynamic EQ, Yamaha YPAO Volume and ISO226 Loudness Compensation Solutions with Dirac Live
- Calculate the exact curves based on two blended ISO226:2003 approaches based on hundreds of hours of research, measurement, number crunching and testing.
- Configure and print out your own personalised cheat sheet based on your listening habits that enables you to switch between Dirac Live slots based on volume / content level OR based on input source.
- Calculation spreadsheet (Dirac Live Curve Editor Excel Tool) that
- allows you to switch between base curves
- select loudness compensation strategies and select the compensation amount based on volume and offsets
- add your own custom base curves
- add your own unique corrections based on your room if needed
- edit the Dirac Live Target files with the help of the spreadsheet and included guide
- Customised Dirac Live Target files that are ready to load based on your requirements without having to mess with a spreadsheet (compatible with Dirac Live 3.X)
- A section on Content Mastering for different content (new in v2.0)
- Reworked Loudness Compensation Chapters (reworked in v2.0)
- A section on Volume and Amplification (new in v2.0)
- 100+ pages of dense but easy to understand material
- 30+ diagrams explaining the concepts in a visual manner
- Lots of easy to understand explanations to guide you through each step of the process.

I note that the mic pattern are the same for Audyssey and Dirac. I wonder if I can also use those mic patterns with ARC Genesis (Anthem) or if ARC really expect that you follow the exact proposed pattern in the software?
Hi Yanick,
Not quite. I say in the guide that Dirac’s own mic patterns should be used with Dirac as they work very well. The Audyssey mic patterns were left in, in case they are needed for troubleshooting.
I would recommend the same for ARC Genesis: follow their own patterns. However, if you are interested, you can give the tight or medium patterns a go and see if they work well with ARC.
Roland-thank you for your quick response:
I have watched the video you suggested several times and many others prior to this email. I have run Audyssey multiple times. I believe I can run Dirac Live and understand the Dirac process for the most part. I have no problem booking a time to talk with you, but I would like to ask these few simple questions first to see if you think that would be necessary. My plan would be to use option 2. Here are my questions.
1. Filters: Do you load the same filter that is calculated by LM EXCELL TOOL into all speaker groups including subwoofers?
2. Which Dirac filters do you suggest using AUD or SHC1?
3. I believe you have to do this for each input-correct?
4. How do you go about saving the file after you have exported the file to your receiver without having to run Dirac live again for the next input?
5. Don’t quite understand this part. Do you have to load a base curve first? And when do you do this or is this for only using option #1?
6. Adjusting surround speakers: the db’s that are calculated from the LM excel tool-Do you adjust them in levels in your AVR after calibration?
7. Last question how do you save or copy your calibration so in the future you can add different filters or do you have to run Dirac over again?
Hi Mike,
No worries at all. Please see below for the answers to your questions:
1. Yes, you load the same filter into all speaker groups including the subs. Obviously, the subs will not have the curtains pulled full-range.
2. Well, as described in the guide, it is up to you regarding your preference. I would personally use the SHC1 curves as they are fully filtered based on the ISO standard. The Audyssey curves are there if you need a one to one match to Audyssey’s curves as measured on their implementation of XT32. The guide does provide a bit more guidance so I would recommend re-reading that chapter.
3. Nope, the filters are loaded into one of 3 memory slots. So once you select which 3 to load, you can select the one of them per input. You do that on the AVR however.
4. When you run Dirac, you save your run as a project file. You can re-open that file, load a new target curve and save the result into a different memory slot on the AVR. You don’t need to re-run Dirac. I would recommend consulting the Dirac Live 3 manual to find your way around the menus if still unsure. Or just give it a go.
5. Well, if you are using the spreadsheet to calculate your corrections, then you do need to select a base curve in that spreadsheet before you apply the corrections. However, it might be easier to use the pre-made files (there’s ones for SHC1).
6. Yes, you do this in the AVR after calibration. Exactly. Now I believe each Dirac Memory Slot should allow you to have different speaker levels which is helpful. If they don’t, the Quick Select memory function should allow you to change the speaker levels using the options menu and save that. Refer to your Denon or Marantz manual on this function.
7. You save your project file from the file menu after you have run Dirac. I think they should have covered this in the video hopefully. But basically once you completed a run, everything can be saved as a project.
The video we are referencing is below for everyone’s benefit:

There’s also a longer webinar about the Dirac Live feature on Denon / Marantz AVRs here:

Ultimately, it will only start making sense as you give it a go and start doing it step by step and use the software tools. Although I know it’s a bit scary at first. Dirac isn’t exactly going to win awards for being user-friendly.
Is this going to work with Pioneer VSX-LX305?
Hey Mike. Yes, it will. Any AVR with full-band Dirac Live can take advantage of the included curves and guidance.
Great. One more question. Is it possible to import current settings/calibration data from the amp and edit them or I will have to calibrate again to be able to edit curves?
No, you can import new curves, as long as you saved your project! You just open it and do the necessary edits and upload back into the AVR. 🙂
But I recommend you edit the surround volumes for each curve. There’s a spreadsheet there to help you! But you have to read the relevant chapter first.
Hi is this still good for dirac live 3 w multi sub? I just did mine and im disappointed at the lack of low end bass.
Hi Jonathan,
Yes, loudness compensation curves can help. The question is how much of your problem is lack of even bass coverage versus the tone curve. In any case, I can’t listen to Dirac without either proper volume on the dial or a proper curve loaded.
