    calculating the dynamic range of your music files in Ubuntu

    If you are interested in calculating the dynamic range of your music files you can use the foobar2000 1.3.16 / Dynamic Range Meter 1.1.1 under Wine

    DR (or Dynamic Range) is a term for the degree of dynamic variation within a piece of music or album. Low values (e.g. DR3) reflect a high abuse of compression. Tracks that are DR3 have a range of three decibels between the average and peak program signal. A natural recording, with a low amount of dynamic processing, would have a much higher DR value (e.g. DR12+). The DR system is intended to avoid black and white judgment of dynamic quality. While DR7 is low for rock music or very low for Jazz, it is quite acceptable for electronic club music which has nowadays often values below DR4. All values above DR12 have generally a high dynamic quality.

    OR


    you can use a native Linux command-line tool >>


    DR14 T.meter >>

    https://sourceforge.net/projects/dr1...l.deb/download


    it may tell you on 16.04 that 2 things are missing

    faac and python-support so >>

    Code:
    wget http://launchpadlibrarian.net/109052632/python-support_1.0.15_all.deb
    sudo dpkg -i python-support_1.0.15_all.deb
    Code:
    sudo apt install faad

    then you can install DR14 T.meter deb linked above
    ==========

    USAGE:

    ● enter a folder and run
    Code:
    dr14_tmeter
    ● for a single file you run>>
    Code:
    dr14_tmeter -f NAMEOFFILE

    It gives you this kind of reading [here on a digitized cassette]

    Code:
