OK, digging into it, I see that they came up with the DR meter before the EBU "Loudness range" was set (and neither had anything but stereo at the time). https://web.archive.org/web/20111028114837/http://dynamicrange.de/ar/new-free-ebu128-vst-meter-plugin-pc-available kinda indicates they should agree, and so does the common 3-second window, but ...
So we have a standard and a defunct "official" ...

Anyway, thanks for maintaining a consistent one. I have used that extensively to rough-sort when CD ripping metadata (that were acquired automatically) gave bogus release years and mastering info. The "scale" doesn't really matter as long as the numbers help me sort and identify. Of course I don't need a DR figure to understand that a 5.1 version is not the same pressing as a CDDA version.

As I said, the calculation of DR is specified and it doesn't tell you to filter out channels by any criteria. There is no "unofficial multi-channel extension", there is only the specification. You can read it here: https://web.archive.org/web/20131206121248/http://www.dynamicrange.de/sites/default/files/Measuring%20DR%20ENv3.pdf.

I see that the the original foobar2000 component actually ignored completely blank channel, though I'd count that as a bug. It for example prints peak and RMS for such channels as "-1.#J".
Simply adding minimal dither noise to the channel triggers the old component to use the channel like it should be used. Just because a channel has DR0 doesn't mean it's not there.

You are right that the exclusion criteria you quoted from MMH isn't academic. It's completely made up. If you are following DR specs you can't invent your own rules.
If you have been scanning your files with MMH you might want to double check the results. I scanned three test files with it and for one it claimed front left and front right channels to be DR2/3 when in reality the channels were around DR10.

Engineering specifications get updated all the time when issues or ambiguities are found. 

Spec quote: "The overall DR is finally calculated as the average of the channel DR values rounded to the next integer value. "

I would submit this sentence was meant to apply only to stereo (roughly equal levels),  not for surround sound channels with large differences in level.   Casual specs like this are not pure mathematics or ironclad (legal) laws and cannot be interpreted without engineering judgement.

You could ask Friedemann Tischmeyer (MAAT)(*), but I submit that the above line does not apply to surround sound multichannel.   My evidence:  The TT DR utility did not allow calculation of overall DR beyond stereo, the current MAAT DROffline utility does not allow calculation of DR beyond stereo and the professional $50 MAAT DROffline MkII does not allow the calculation of DR beyond stereo.  And I don't think it is because MAAT is lazy.   Note, that the MAAT DROffline(s) refuses to process MP3s by design.

(*) Though Tischmeyer probably would not respond because MAAT DROffline is the only "Official"/"Real" DR calculator, i.e. you are a competitor.   I guess you ask: "Can I take MAAT DROffline DRs for surround channels and average them together to make a "MAAT Official" overall DR?"

I hope @Case will not change the calculations nor remove multichannel from DR Meter:)

If no consensus is reached about how to do it, I agree this would at least make some sense for multi-channel (as an optional advanced setting).

Anyway I think that at least ideally, the average should be volume-weighted in some manner, so that a blank channel counts for nothing. And, for the sake of the argument: what if one "was blank, but dithered in the mastering" so every block has something - then way out in the roundoff.

I agree about point below though, even if I understand Case's points.

On one hand. it makes no sense at all that channel-volume levels affect DR scores, that kinda defeats the purpose of DR and it should be taken into consideration when computing averages.

On the other hand, if you split channels as tracks, then the average DR would also be the average of every track. And it doesn't matter if they have different volume levels... So considering every stream as a single entity, it doesn't matter if it's a channel, a track or whatever. They are all averaged the same.

One could also argue that an artificial track where the L channel has a DR1 and a R channel with DR14 but mostly silent would also output "wrong" DR. And that's "true", that value is mostly useless. You have just fooled the meter (like the all pass EQ filter + phase changes). It's not multi-channel problem only. (this is what Case's points are about, it's just how the standard works)

I would say, in this case the standard is simply incomplete, and Porcus solution makes much more sense to "patch" the standard, even if it's an opt in option.

Note, I am not asking for any change in calculation or removal of multichannel.  Multichannel capability is convenient for a "batch" run of the DR algorithm.  Just the output of a "caveat" line for the overall value in the log file when outputing surround overall DRs something like "Overall DR is based on a simple average of the individual surround channel DRs".   One would hope that existing DR log processing routines could handle a extra information line without getting an error.

An interesting search in the DR Database is to put "Atmos" in the Album search field and leaving "Artist" blank.   You will get results based on the averages and results based on downmixes.  What you do not see is DR logs with all the information for all the channels.

I think the problem is that all the great surround per channel data is not spammed into the log in some form.   If there was per channel data in the log, you could see that the "DR14" track 1 is actually  DR 8.81/8.40 dB  for the dominant front channels.

The log format mimics the reference design. Single track scans have all the details, album scans are just a summary.

I can add channel DR results to the album log, if you think it won't cause problems.

Re: Dynamic Range plugin

Reply #184 –
I seem to have suffered from tunnel vision last night, the test component and example log I posted just repeated the channel results of the first track for all the tracks.
Unfortunately this forum still doesn't allow me to remove the attachments from old posts, so I can't nuke the dangerously buggy component.

Here's a fixed test version that reports the information from the correct channels. And I realized the reported bitdepth was incorrect for HDCDs (it reported 16 from static information). This version gets the decoded bitdepth value after possible decode postprocessors.

I'll make an official release if @spongebob128 confirms log mutilations like these don't cause issues for log consumers.

@mexx : I was going to implement time estimate display yesterday, but the SDK helper for these threaded tasks doesn't support status bar display like is seen in the built-in ReplayGain scanner. I don't feel like inventing my own tools when the SDK offers otherwise superb solution, so for now this is all you get.

...I was going to implement time estimate display yesterday, but the SDK helper for these threaded tasks doesn't support status bar display like is seen in the built-in ReplayGain scanner. I don't feel like inventing my own tools when the SDK offers otherwise superb solution, so for now this is all you get.

OK, no problem. It would have been nice, but it's not absolutely necessary. Thanks for your effort.

I'll make an official release if @spongebob128 confirms log mutilations like these don't cause issues for log consumers.


Thank you for this great efforts.  I wish I had such god like powers (this week I found that my code mistake caused an engineering results disaster).  I guess the main consumer of the log is the Dynamic Range Database "https://dr.loudness-war.info/".   I currently I do not have any insight in what the DR Database submission code will except or won't except (though I guess I could test it myself).    From my understanding, a main pain for the database website is the problems with the RIAA (music industry piracy enforcement) if the submissions are not carefully screened to make sure they do not contain any music download information.   This means the log file may be extremely restricted to be a certain format.   Currently, they only have to check the "Comments Field" for "bad" information (yes, they check every one).

The runner of site seems to have some motivation to maybe change the code if necessary.  In this post:

Downmixes are problematic because if all the tracks of a 5.1 mix are extremely compressed, the downmix would still look and measure rather good. So, DR values of stereo downmixes of surround mixes have no real significance. There are also many ways to downmix, like at which volumes you mix the different channels, like rear channels at -3 dB or -6 dB.

I agree that downmixing opens up a whole can of worms, especially for coming up with repeatable authoritative DR numbers.

Providing the individual surround channel numbers seems to be good solution.  The only addition is that I would like to see the RMS numbers too.    In this way you can get a "feeling" for how much a channel's DR number would effect the overall DR.   An average "pseudo peak"  could always be inferred by  (DR + RMS) for a track so the actual peak value is not that important.

I just uploaded version 1.0 that reports per-channel DR and RMS statistics for multichannel albums. And I added time information to the titlebar of the progress dialog.

Would it be possible to log stereo L/R channels separately?
This might be a bad idea as the default behavior, but could it be configurable?

Re: Dynamic Range plugin

Reply #190 –
Serves me right for reusing padding code I wrote for numeric values. Fixed version uploaded that can calculate string lengths correctly regardless of special characters. And I added an option to include per-channel statistics for stereo albums too.

@Case
thank you for new additions to the component.
One remark regarding new method of bitdepth display in the log. In case of HDCDs it can be misleading/confusing as we have 16bit file and get 24bits in the log. Plus I scanned a file that has TF but no PE nor LLE so your TPS shows 17bits but new DR shows 24bits which may again be confusing (I presume those are different values - "measured" vs. "decoded to"). Maybe it would be better to show both values in the log - input bitdepth (16) and decoded bitdepth (24) or at least name or rename the visible value so that we know which one is displayed.

Re: Dynamic Range plugin

Reply #192 –
My recommendation has always been not to pretend that fake HDCDs are HDCD-enabled. That way you do not get any confusions anywhere. Note that the bit depth is purely what the source reports, it will never be fact checked to see if the bits are actually present.

I strongly disagree that log should contain values that are irrelevant, like what the source file specs are prior to decoding.
