==Introduction to DR14 T.meter==

'''DR14 T.meter''' is a free and opens source command line tool for computing the '''DR - Dynamic Range''' of your music according to the procedure used in the off-line meter released by the '''[http://www.pleasurizemusic.com/ Pleasurize Music Foundation]'''. 

This tool is very useful to measure how is loud your music and for understanding that a good quality album always has also a good dynamic, and it's also useful for understanding the effects of the so called [http://en.wikipedia.org/wiki/Loudness_war loudness war]. 

'''Dr14 t.meter''' is released under the terms of the  [http://www.gnu.org/copyleft/gpl.html GNU GPLv3] license and  is intended for the '''Linux''' users that can not use the Windows application released by the Pleasurize Music Foundation or the [http://www.jokhan.demon.nl/AudioStats/index.htm plugin for Foobar2000]. 

I've largely tested this application and it has always returned results identical to those of the official off-line meter.

==How it works:==

it simply scans a given directory and it compute the DR value of the audio files stored in the directory. Actually we support the mp3, flac, m4a, ape and ogg formats. 
As a result it writes the resulting values in three files located in the same directory of the audio files: 

dr14.txt 
A tabbed text file 
dr14_bbcode.txt 
A table formatted in bbcode (useful for forums) 
dr14.html 
An html table, for your web-site or blog. 

To have an idea of the returned tables visit: [[DR Examples|DR results]] . For a full list of the features visit the featuers page.

==System requirement:==

The tool is written in python (3) so you must install the python package in your system and the libraries numpy and scipy as dependencies. Dr14-tmeter works correctly with python 2 and python 3. 
For decoding the audio-files the packages: '''lame''' '''flac''' '''vorbis-tools''' '''faad''' (2) and '''ffmpeg''' are required!

==How to use:==

Install in your system the tool or enter in the directory where you have putted the tool and give the command: 

 > dr14_tmeter [your music directory] 

When the computation is finished you will find in your music directory the file ''dr14.txt'' described above.  
For example if your favorite album is stored in the directory ''/home/donald-duck/mymusic/wow music'' you shold take the command: 

 > dr14_tmeter "/home/donald-duck/mymusic/wow music" -m 

If you are located in a music directory you should give the command without options, and it scan the current directory:
 
 > dr14_tmeter 

For more information type the command: 

 > ./dr14_tmeter --help 

Read also '''[[How to Use]]''' page, for more detailed tips

or read the man page. 

==Installation:==

*If you use '''Ubuntu''', '''Limux Mint''' and '''Debian''' download and install the package in .deb format. 
*If you use '''Fedora''' you shoould use the packade in rpm format, and for the rpm based distros like '''Suse''' or '''Mandriva''' you should try the source rpm package. 
*If you are an '''ArchLinux''' user use the PKGBUILD provided in the AUR repository. 

If you are using another distro use the python installer: 
Enter in the package directory and with the root privileges type the command: 
 > python setup.py install --root="/" --prefix="usr" --optimize=1 

This command will install the tool in your /usr/bin directory. 
After the installation you should use the command dr14_tmeter from the shell.
