DR14 T.meter is a free and opens source command line tool for computing the Dynamic Range of your music according to the procedure used in the off-line meter released by the 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 loudness war.

        -r, --recursive       Scan recursively the subdirectories
        -a, --append          Append all results in a single file; it should be used
                              in couple with -r
        -b, --basic_table     Write the resulting tables in the basic format
        -n, --turn_off_out    do not writes the output files
        -p, --print_std_out   writes the full result on the std_out

                              Write the resultings files into the given directory
        -t {h,t,b,w,a}, --tables {h,t,b,w,a}
                              Select the output files to be written. h=html t=text
                              b=bbcode w=mediawiki a=all_formats
        -f, --file            Compute the DR14 of a single file and exit
        -d, --dr_database     Output file compatible with the DR database at
        --hist                Plot the histogram of dynamic of a single file and
        --lev_hist            Plot the histogram of the saples levels of a single
                              file and exit
        --spectrogram         Plot the spectrogram of a single file and exit (beta)
        --plot_track          Plot the track of the given file and exit
        --plot_track_dst      Plot the track in a cool manner of the given file and  exit
        --compress {very_soft,v,soft,s,medium,m,hard,h,very_hard,vh}
                              Perform the dynamic compression on a single file and
                              exit, the resulting track will be written in a temp
