Mp3 metadata populator app

Introduction

This app does what you think it does. Mark important parts of the audio's file name and the metadata will be generated for you. It is a quick side project so it has its bugs

Technologies

Setup

To run this project, place it in your music folder, and run $python3 manager.py. For some music apps, generated '.jpg' covers might not work. You would then have to update them with another application (simple load and save with Mp3tag might work).

Quick tutorial

Almost everything you do, you do by changing the file name. The first way to do it, is to place the metadata inside the curly brackets {}. You define the field, and the corresponding metadata will be generated.
For example:

{-a Nikolay $1 -c Chopin -d 2015 -i lugansky_chopin -b $c by $a} Lugansky Chopin Piano Concerto No. 1 in E minor.mp3

will output the .mp3 file with the following metadata fields.

  • Artist: Nikolai Lugansky
  • Composer: Chopin
  • Release date: 2015
  • Front cover: Covers/lugansky_chopin.jpg
  • Album: Chopin by Nikolai Lugansky

$1 stands for the first word in the file name.
Note that the order of the fields matters for some are generated using others.
Additionally there are the default values for each field, so that they are generated despite you not providing their values. They are defined in the Manager/MetaFile class and can be changed easily.
The second way to populate the fields is to place the $[] marks just before the corresponding words.
For example:

$b2 $a Lugansky $c Chopin $t- Piano Concerto No. 1 $ in E minor $i lugansky_chopin.mp3

will output:

  • Artist: Lugansky
  • Composer: Chopin
  • Album: Lugansky Chopin
  • Title: Piano Concerto No. 1
  • Front cover: Covers/lugansky_chopin.jpg
    The $b2 says that the next 2 words are for the album. $c is an equivalent for $c1. $t- means that the title is the words until the next $ character.
    Additionally there is the name replacing functionality that maps the provided name-values to known artists or composers defined in the Manager/NameReplacer.py file. For example Bach would be changed to Johann Sebastian Bach.

TODO

The planned functionalities are:

  • Expanding the command line arguments from 0 to more than 0. (ex. giving different default values)
  • Trimming the videos
