ffixer

Dependencies:

  • eye3D
  • grep command-line tool. grep can be found in the grep package on major Linux distributions.
  • sed command-line tool. sed can be found in the sed package on major Linux distributions.

This utility does a few things automatically that I like to keep my collection in order.

First, it finds MP3 files that have song titles like "Scratches All Down My Back (Buckcherry vs.Toto)" and moves the artists that are in the parentheses or brackets to the "Album Artist" field. Searches recursively from the directory you run it in, and stores a CSV of changes made in your $HOME directory. Use --dryrun as an option first if you like.

Second, it fills in the album artist and composer fields if they are empty, preferentially using the artist tag. I like this because different music players sort "artists" using different fields.

Third, it standardizes all the "date" fields (release date, original release date, and recording date) to YYYY only and fills in any empty fields.

Finally, it does all this while preserving the original file modification time so that your collection isn't a flying mess of "new" tracks.

ffixer_covers

This script walks recursively from the directory it starts from and ensures there are both cover.jpg and folder.jpg files. If none exists in the directory, it attempts to extract them from the ID3 tags.

It will also embed found cover art into the ID3 tags if none exists, and will attempt (if not found in any of the above) to find a cover on the interwebs.

Dependencies:

mpdcontrol.sh

Select whether you want to choose a playlist, or by album, artist, or genre. Clears playlist, adds what you chose, starts playing. The SSH version is for exactly that, especially if you don't have pick on that machine.

The mpdcontrol_add.sh file does not clear the queue so that you can add to the existing playlist.

Dependencies:

output

terminal_multiplexer

Uses tmux, xterm, ncmpcpp, cava, and terminal covers to provide a nice layout. Title set to screen by wmctrl. No tmux.conf file needed. Inspired by this reddit post.

Dependencies:

One or more of the following:

AA-lib asciiart img2txt

bpmhelper.sh

Uses the bpm-tools package, which analyzes BPM quite nicely on linux, but then writes tags that overwrite album and genre tags. So this wrapper uses eyeD3 to determine if a BPM is already written, then analyzes the file, then uses eyeD3 to do the writing to the file. I already have eyeD3 for the album art script; a solution that does not rely on that dependency can be found at bpmwrap.

bpm-tools outputs error messages if you do not have id3v2 and sox with mp3 headers already installed and thus makes the script fail. You can either tweak the script or install the packages sox, libsox-fmt-mp3, and id3v2.

Accepts two command line arguments (optional)

Use --save-existing to save existing data.
Use --skip-existing to skip further analysis of those that have existing BPM Use --quiet to suppress output (eyeD3 may still output to the screen)

Analyzes the current directory and all subdirectories.

Dependencies

mp3gainhelper.sh

Performs mp3gain analysis and writes to id3 tags. The MP3Gain utility apparently writes by default to APE tags, which aren't used by MPD. But apparently mp3gain has issues corrupting ID3 data if you write directly to ID3 tags, and will just crash and abort if it runs into an error instead of continuing onward.

Accepts only one command line argument (optional) giving the directory to analyze. Otherwise analyzes the current directory and all subdirectories.

Dependencies:

webserver.covers.sh

Very simple script to make your album covers accessible by MPoD or other remote clients without exposing your entire music directory by copying the cover files to the webserver root. (You need to edit this, obvs.)

Dependencies:

terminalcovers.sh

A kind of hack-y way to show terminal covers in the terminal. Uses either AA-lib or libcaca. AA-lib looks MUCH better, but doesn't automatically exit, so requires killall (yeah, that sucks). You will need to edit the script to choose a different renderer.

Dependencies:

One or more of the following:

AA-lib output

AA-lib

libcaca output

LibCaca

mediakey.sh

This script uses the MPRIS interface to control your media players.
Currently supported players include MPD, Pithos, Audacious, and Clementine
