Dr14 T.meter is an open source command line tool that computes the dynamic range of your music files. It’s a tool that I use in order to create reports for each of my FLAC albums I have in my music library.

Installing it in Archlinux was pretty easy:

$ yaourt -S dr14_tmeter

In order to create a report for an album you need the following command:

$ dr14_tmeter /path/to/album/

What is really nice about it is that you can use it recursively in order to create dynamic range repors for multiple albums at once:

$ dr14_tmeter -r /path/to/album/library/

The result of these commands is a file within the album directory named dr14.txt. Here is an example of such a file:
