You can see one post above yours where your complaint should go. It's wasted here.

This plugin has one annoying bug, in grouping mode it doesnot regard album artist. This leading to treat each single track on more artists albums as separate album. Causing race conditions on r/w operations (especially multitrack albums). Should enable a custom grouping pattern similar like replaygain scanner uses.


Regarding this bug, it indeed confuses artists on albums with track artists.
But it does not try to simultaneously read multiple tracks of the CD ! Maybe you should update your foobar2000 ?
And also, I advise to uncheck the Group playlist items in Preferences (CTRL+P) > Advanced > Tools > Dynamic range meter.
Only this way, the log file for an album with multiple track artists will be complete.

That's right, however the option of mass scanning is not available (I use always the latest foobar build anyway).

You mean you can’t scan several albums at once ? Well maybe but I don’t know as I only scan one CD (scanning CD itself in CD drive) at a time.

Not a very smart suggestion. If you uncheck this and scan several albums at once, all albums will be assigned the average dynamic rating across all albums.

You have doubts on my smartness but I said I scan CD per CD (CDDA, not FLAC, MP3, etc.). I have no such problem you describe. wink.gif
Anyway I said it’s the only way and I think it’s still true. If you don’t do that a single album will be split in as many as you have distinct track artists.

I use right-click show log as it cannot write any file on an Audio CD.
You can try that.

The author website is now down but you can still see it in webarchive and still download the foo_dynamic_range 1.1.1 plugin from this page I found. (same foo_dynamic_range_1.1.1.zip file mirror, thanks !).

Would this tool give sensible results if used on a 6-channel track? How does it calculate a DR?

I'm curious - I was reading that the DR values can come out different depending on how the files have been encoded. Is it still worthwhile using this tool to determine the DR of an mp3 album, especially if it has a low bitrate? I get the idea that the DR values of the actual CD would be more accurately reflected in a lossless rip, but I could be wrong.

I am pretty much a fanatical audiophile and my foobar2000 setup has this Dynamic Range plugin installed.....and I hardly ever use it! In my opinion the stats produced by this plugin are not much of a big deal at all for the purpose of judging the sound quality of an album and comparing to other releases.

Having said that, this plugin is helpful when you are trying to calculate a peak gain value to be applied with sound processing software (e.g. Saracon,) for the purpose of preventing clipping and maximizing volume when doing conversion jobs such as SACD DSD audio to PCM WAV.

foo_dynamic_range.dll is not the only way of reporting dynamic range and peak info; it can also be reported using the command line tool r128gain.exe

FYI, an actual comparison of the reports generated by those two tools on the same target album on my computer:

foo_dynamic_range.dll (@foobar2000 -> items in playlist -> context menu: Dynamic Range Meter)
CODE
Track1          Range: 15           Peak: -5.50 dB            RMS: -25.87 dB
Track2          Range: 18           Peak: -9.13 dB            RMS: -33.75 dB
Track3          Range: 16           Peak: -10.57 dB           RMS: -32.24 dB
Track4          Range: 15           Peak: -14.48 dB           RMS: -36.47 dB
Track5          Range: 14           Peak: -5.20 dB            RMS: -25.45 dB


r128gain.exe (@CommandPrompt -> r128gain.exe --r128 --db --progress=on "C:\<TargetFolder>")
CODE
Track1          Range: 19.9 db           Peak: -5.5 dbFS            RMS: -24.6 dbFS
Track2          Range: 19.2 db           Peak: -9.1 dbFS            RMS: -32.6 dbFS
Track3          Range: 18.6 db           Peak: -10.6 dbFS           RMS: -31.4 dbFS
Track4          Range: 18.3 db           Peak: -14.5 dbFS           RMS: -35.5 dbFS
Track5          Range: 21.0 db           Peak: -5.2 dbFS            RMS: -23.8 dbFS


As you can see, the tools do not report the exact same values for all calculations, but they do report accurate enough peak information to be used for applying 'clip-free gain' in further processing tasks. You use the lowest absolute peak number as 'reference value', which in this case is -5.20 and subtract one-hundredth to give some headroom, giving us -5.19.

So, the number to use as gain value in Saracon for the above case will be +5.19 , which will create output files having maximum volume with clip-free gain.
If the lowest absolute peak number 'reference value' is over 6dB , we insert +6dB (i.e. it is the ceiling value, no higher value to be used).

----

@marc2003,
Is there any chance you could create a WSH Panel mod script to run and display the r128gain dynamic range report ....that would be really cool!!!
It also gives people the option of NOT having to install this foo_dynamic_range plugin to view this type of information.
Thanks.

I tried converting a FLAC album to MP3 V4 (I deliberately chose a poorer bitrate, typical of what might be the rare lowest-quality audio I'd find in my library) and then ran the dynamic range plugin on the converted album. Here's the results:

FLAC:
CODE
DR         Peak         RMS     Duration Track
--------------------------------------------------------------------------------
DR15      -0.16 dB   -20.86 dB     15:16 06-Les Préludes
DR16      -1.62 dB   -24.56 dB     15:36 01-Symphonie fantastique: I. Rêveries - Passions
DR14      -5.44 dB   -24.86 dB      6:23 02-Symphonie fantastique: II. Un bal
DR19      -0.04 dB   -28.23 dB     16:15 03-Symphonie fantastique: III. Scène aux champs
DR13       0.00 dB   -18.15 dB      4:55 04-Symphonie fantastique: IV. Marche au supplice
DR14       0.00 dB   -20.32 dB     10:35 05-Symphonie fantastique: V. Songe d'une nuit du sabbat
--------------------------------------------------------------------------------


MP3 V4:
CODE
DR         Peak         RMS     Duration Track
--------------------------------------------------------------------------------
DR15      -0.36 dB   -20.86 dB     15:16 06-Les Préludes
DR16      -1.31 dB   -24.56 dB     15:36 01-Symphonie fantastique: I. Rêveries - Passions
DR14      -5.37 dB   -24.86 dB      6:23 02-Symphonie fantastique: II. Un bal
DR19      -0.05 dB   -28.23 dB     16:15 03-Symphonie fantastique: III. Scène aux champs
DR14       0.00 dB   -18.15 dB      4:55 04-Symphonie fantastique: IV. Marche au supplice
DR14       0.00 dB   -20.32 dB     10:35 05-Symphonie fantastique: V. Songe d'une nuit du sabbat
--------------------------------------------------------------------------------


There are only slight differences in the calculated peaks.

instead they have to install WSH panel mod, add a panel to their layout, download and extract my files into their profile folder, turn off safe mode and then import the script. much easier.... tongue.gif

if you really want to, my existing simple text reader script can display text files. by default it will load the first txt/log file it finds in the current playing track's folder but you can customise the folder path/filename with any titleformatting you like.

Vinyls are reported as having higher DR than CD using the same master, so it might not be accurate for comparing lossy encoded files either.

It would be nice it was updated to include R128 peak-to-loudness-ratio metric that's used by a few pro audio tools.
