DR14 T.meter a dynamic range meter for Linux

bred · 2012-01-03 09:30:30

dr14_tmeter is a simple command line tool that compute the DR (dynamic range) of the audio files in your music collection.
dr14 t.meter uses is based on the algorithm described by the Pleasurize Music Foundation.

For understanding the main propose of the DR14 visit:
http://www.pleasurizemusic.com/

And for having a better idea about the loudness war:
http://en.wikipedia.org/wiki/Loudness_war

In a few words higher is the DR of an audio track will be more pleasant to hear.

The tool is very simple to use, you must type the command by specifying a music directory:

dr14_tmeter [your music directory] -m

for example:

dr14_tmeter /media/usb_disk/data/Music/Music/Sex\ Pistols/ -m

And it starts!

After the computation by default it writes the results in three tables named dr14.txt dr14.html and dr14_ddcode.txt located in the music directory.

The option -m for enabling the multithread is highly recommended!

For more details and options:

dr14_tmeter --help

AUR:
https://aur.archlinux.org/packages.php?ID=54278

Github:

Il tool is written in python and works correctely with python2 and python3.
It support the audio formats: mp3 flac ogg ape wma mp4

Can you make it to scan recursive?

For the moment try this command

for i in *; do dr14_tmeter -m "$i"; done

That's not recursive, but it's better than noting.

Added to wish-list

Thank you!

Tristelune · 2012-01-04 20:36:31

Thank you for this tool I was just searching some tool to analyse the dynamic range!!!

But I have a problem: for some flac files I get this kind of error:

 - ERROR ! 
Elapsed time: 1.18
No audio files found

In the directory there are some flac files.

Do you have any idea ? What input do you need ?

Copy and paste the command line and the full output.

It uses the flac command for reading the files, so you must install the flac package with pacman.

pacman -Sy flac

The full dependencies list: faad2 ffmpeg flac lame python python-numpy python-scipy vorbis-tools

See also the AUR package:

I assume you are the developper of this tool. I've sent you a mail and
the flac package is installed on my computer. Such that the other also
know it seems to be a bug with flac 24 bits/96khz. For every cd I ripped, also
16 bits/44.1 khz, the tool works perfectly.

Yes, I'm the developer.
For being more precise is a bug wit the scipy libs that don't recognize the 24 bits sampling.

If you want to measure the DR of your 24 bits files, convert its to the mp3 format and measure these files.
Normally there's no difference.

Ok, thank you for for the suggestion. Should I make a bug report for the scipy libs ?

That's not necessary

http://projects.scipy.org/scipy/ticket/1405

Is a well known problem.
Maybe we should try to send an example.

Ok, as I can see somebody already posted an example. But I'll probably send a
mail to ask if they need one..... just to show that other are also interested by a fix .

Now yes.

The version 0.8.3 has the option for the recursive scan.

Try it!

News ....

dr14 t.meter 1.0.5

Now it's capable to perform the Dynamic compression of the audio files; so if you want to experiment what's happen with the compression ... try it.

For example:

> dr14_tmeter 01-The_rolling_Stones_paint_it_black.mp3 --compress vh

The resulting file will be written in /tmp .... What happen to you music with the compression http://i49.tinypic.com/1i1nhi.jpg (the compressed file is bellow)

Now it support the 24bit files (via down sampling)

And the computation speed is dramatically increased.

It's doing also some audio analysis like histograms ...

Now it's also fully compatible with the DR database: http://www.dr.loudness-war.info/

Web page:
http://dr14tmeter.sourceforge.net

AUR:
https://aur.archlinux.org/packages.php?ID=54278

Github
https://github.com/simon-r/dr14_t.meter

That's the spectrogram of an audio file:

Enjoy ....

I'm having an issue using dr14_tmeter on MP3 files. I always get:

dr14_tmeter -f Wonderful\ -\ Everclear.mp3 2012-10-18 16:55:12,190 - dr14log - DEBUG - ciao
/mnt/R/Music/Top 40/Wonderful - Everclear.mp3

Unexpected error: (<type 'exceptions.ValueError'>, ValueError('total size of new array must be unchanged',), <traceback object at 0xa91ee8c>)

- ERROR !

It does seem to work fine on WAV files. LAME is installed. Any idea?

Have you updated to python 3.3 ?
If yes, rebuild the package via AUR and let's me known.

...but i agree that having sources with higer DR is better so that you can compress it according to your needs.

Higher DR is not better quality, but generally, compression don't improve the quality.

Hello,

I tried your tool with my music collection. It worked well for a couple hundred of songs, but then I encountered an error. Usually, it prints the name of the song followed by "DR xx", but just before the error message, it only printed "DR = 11" right at the beginning of the line.

My music collection is in ~/Music. From ~, I launched the following command :

dr14_tmeter -ra Music

The actual error message was :

Traceback (most recent call last):

In these tracks is specified the artist?
(See metadata).

There was a soundsort utility, but it only works on WAV and not MP3s.

I've seen, but dr14 is a completely different thing.
soundsort seems to be an audio classifier.
