How to read mp3 tags in shell?

  • 772

Is there a way to read the mp3 tags of a file from the shell? Something like: mp3tags MyFile.mp3 author should output the author-tag of an mp3-file.

command-line

  1. You can also use ffprobe which is part of ffmpeg.

    sudo apt-get install ffmpeg
ffprobe file.mp3

    If you don't want other information, like track length and so on, you can combine the output with grep:

    ffprobe file.mp3 2>&1 | grep -A90 'Metadata:'

    Or in order to get only the author:

    ffprobe -loglevel error -show_entries format_tags=artist -of default=noprint_wrappers=1:nokey=1 file.mp3

    You can select other tags by separating them with a comma, such as format_tags=title,album.

    I wanted to search for a keyword in all mp3 files in a folder. The folder had 486 files, so it became interesting to know which of the solutions mentioned here is the fastest. Here is the loop I used:

    # sudo apt-get install ffmpeg lltag eyed3 mp3info id3v2 libimage-exiftool-perl libid3-tools id3tool

keyword='fill_me_in'

getTitleFF()   { ffprobe "$1" 2>&1 | sed -E -n 's/^ *title *: (.*)/\1/p'; }
getTitleLL()   { lltag --show-tags title "$1" | sed -nE 's/^  TITLE=(.*)/\1/p'; }
getTitleEyed() { eyeD3 2>&1 "$1" | sed -n 's|\x1b\[[0-9;]*mtitle[^:]*: ||p'; }
getTitleInfo() { mp3info -p %t "$1"; }
getTitleId3()  { id3v2 -l "$1" | sed -nE 's/^(TIT2 \([^)]*\)|Title *): (.*)/\2/p'; }
getTitleExif() { exiftool -title -b "$1"; }
getTitleId3i() { id3info "$1" | sed -nE 's/^=== TIT2 \([^)]*\): //p'; }
getTitleTool() { id3tool "$1" | sed -n 's|^Song Title:\t||p'; }

for prog in FF LL Eyed Info Id3 Exif Id3i Tool; do
    echo "=== getTitle${prog} ==="
    time \
    for file in *.mp3; do 
        if "getTitle${prog}" "$file" | grep -q "$keyword"; then 
            echo "$file"
        fi
    done
done

    Notes:

    • lltag and mp3info don't find a title, because the files I was using had ID3v2 tags, see the comment by @s-prasanth: How to read mp3 tags in shell?
    • eyeD3 is problematic to use programmatically, because it uses color codes (boldness).
    • eyeD3 and also id3v2 (but only for ID3 v1 tags) return the title and the artist on the same line, which further complicates things; therefore getTitleEyed and sometimes getTitleId3 return both the title and the artist, so please don't copy-paste those functions.

    • getTitleId3 will only work for ID3 v2 tags, because id3v2 has different formats for ID3v1- and ID3v2-tags, i.e.

      Title  :                                 Artist:

      vs. ID3v2:

      TIT2 (Title/songname/content description):

    • As the only program of these 5 eyeD3 prints a red warning for two of the files:

      Invalid mode/bitrate combination for layer II
No ID3 v1.x/v2.x tag found!

      It seems like those two files have ID3v1 tags, because those two files are the only ones where lltag and mp3info can get a title. I'm wondering if this is a bug in eyeD3 as no other program mentioned here has a problem with these files ...

    Results (real time):

     Program  | Version    | Time / s
----------+------------+-----------
 exiftool | 10.25      | 49.5 ± 0.5
 lltag    | 0.14.5     | 41   ± 1.0
 ffprobe  | 3.1.3-1+b3 | 33   ± 0.5
 eyeD3    | 0.6.18     | 24   ± 0.5
 id3info  | 3.8.3      | 4.2  ± 0.1
 id3v2    | 0.1.12     | 2.9  ± 0.1
 id3tool  | 1.2a       | 1.7  ± 0.1
 mp3info  | 0.8.5a     | 1.4  ± 0.1

    Time-wise the winner here is id3tool (mp3info is faster, but doesn't work with ID3 v2). id3v2 is also quite fast, but the getTitleId3 function would need adjustment to also work with ID3v1-tags, which may at worst slow it down by factor 2.

    Ok, I found a program by myself. It is called mp3info and installed by

    sudo apt-get install mp3info

    To get single mp3 tags from a file, one has to call

    mp3info -p %a file.mp3

    which gives the artist of the file. The %a means that one want to get the artist and there are some other keys for the other tags.

  3. You can use eyed3. First, from a terminal, install:

    sudo apt-get install eyed3

    Then, run:

    eyeD3 song.mp3

    Combine that with grep to get specific tags in one line.

    eyeD3 song.mp3 | grep artist

    (to strip all mp3 tags, see HERE)

  4. I prefer to use id3v2, just type id3v2 -l somefile.mp3. You can also see the id3v2 man page for more specific use.

  5. You can try exiftool(Read and write meta information in files).

    "ExifTool is a platform-independent Perl library plus a command-line application for reading, writing and editing meta information in a wide variety of files. ExifTool supports many different metadata formats including EXIF, GPS, IPTC, XMP, JFIF, GeoTIFF, ICC Profile, Photoshop IRB, FlashPix, AFCP and ID3, as well as the maker notes of many digital cameras by Canon, Casio, FLIR, FujiFilm, GE, HP, JVC/Victor, Kodak, Leaf, Minolta/Konica-Minolta, Motorola, Nikon, Nintendo, Olympus/Epson, Panasonic/Leica, Pentax/Asahi, Phase One, Reconyx, Ricoh, Samsung, Sanyo, Sigma/Foveon and Sony." - ExifTool by Phil Harvey

  6. Check out lltag if you are looking for a solution which supports more than just mp3/ID3.

    Install it with:

    sudo apt-get install lltag

    to view all tags with it: (-S is for show)

    lltag -S somefile.mp3

    to view certain tags with it:

    lltag --show-tags artist,album,title,number somefile.mp3

  7. Beets

    You can start with this screencast and the Getting started guide

    Install either:

    pip install beets  # latest version
apt install beets  # repo version

  8. I've just recovered dozens of deleted mp3 files from a memory card using PhotoRec. PhotoRec is not able to recover the original file name, so assigns names to the files in order of recovery - eg. f1234567.mp3.

    I wanted a quick way of reading and listing the ID3 tags so that I could see what the recovered recordings were without having to open, listen to and rename each mp3 file in turn. I'm using Linux Mint 20 ('Ulyana') Cinnamon and have previously installed the free open source app EasyTAG for editing ID3 tags via a GUI.

    If you open EasyTAG and navigate to the folder containing the mp3 files, its default behaviour is to list the file name (eg. f1234567.mp3 assigned by PhotoRec) alongside the Song Title (eg. La Vie En Rose) extracted from the Title field of the ID3 tag for all files in that folder. I appreciate that this does not use the shell as stated in the original question, but is an alternative which is incredibly simple to use. Hope this helps.

  9. I have the same problem and need some app but I have python on my ubuntu, then I decide to use python. you can use the python package tinytag if you have python on your ubuntu

    first, install tinytag using pip

    pip install tinytag

    now

    from tinytag import TinyTag
tag = TinyTag.get('/some/music.mp3')
print('This track is by %s.' % tag.artist)
print('It is %f seconds long.' % tag.duration)
