flac2lib is a simple script I've made (and then expanded with like a milion random ideas) for myself for easier music library management, specifically batch converting flac files into mp3 with regard to my mp3 music library schema.

• Python 3
• Pydub (pip install pydub)
• ffmpeg / libav (required by Pydub)
• PyYAML (pip install PyYAML)
• opencv-python (pip install opencv-python)

Download the files

• Clone the repo:

git clone https://github.com/PokerFacowaty/flac2lib

• ... or simply download flac2lib.py and config.yaml and store them in the same directory

• Open config.yaml
• By default, the file will look like this:

# Docs: https://github.com/PokerFacowaty/flac2lib
flac_albums_dir:
dst_albums_dir:
entire: False
num_albums_to_show: 10
dir_name_prompts: True
latest: False
get_cover_art: True
default_cover_art_name: cover # copied straight to the album folder
cover_art_suffixes: ['jpg', 'png', 'jpeg']
destination_format: mp3
ffmpeg_params: -q:a 2
# For the MP3 preset, use the "ffmpeg option" table in this article
# of the ffmpeg docs:
# https://trac.ffmpeg.org/wiki/Encode/MP3
# Use for other formats accordingly.

Explanations for all config entries:

• flac_albums_dir: - the directory that contains album folders with flac files
• dst_albums_dir: - the destination directory for converted files
• entire: - convert entire albums without asking for a list of songs to be converted; False by default
• num_albums_to_show - the amount of albums that should be listed when albums are presented to be chosen; 10 by default, ignored when entire: is set to True or the -e / --entire option is used
• dir_name_prompts - prompt about album/artist folder paths, uses ARTIST and ALBUM tags for dir and subdir without asking if False; True by default
• latest - pick the most recently modified flac folder; False by default
• get_cover_art - copy the cover art; True by default
• default_cover_art_name - the default name for the main cover art without its suffix; cover by default
• cover_art_suffixes - a list of accepted covert art suffixes; ['jpg', 'png', 'jpeg'] by default
• destination_format - the format that flacs will be converted to
• ffmpeg_params - additional ffmpeg parameters, the preset / bitrate for MP3 should be specified here; -q:a 2 (VB2) by default

To use flac2lib, simply start it when in the same directory:

python flac2lib.py

(or if you have Python 2 installed)

python3 flac2lib.py

• -h, --help - show help
• -c, --config <file> - use a custom config file
• -e, --entire - convert the entire directory
• -s, --source <dir> - specify the source album directory
• -d, --destination <dir> - specify the destination album directory
• -l, --latest - only convert the most recently modified folder in the flac albums directory
• --skip-cover-art - skip the process of copying covert art entirely
• --skip-dir-prompts - skip prompts about album/artist folder paths, use ARTIST and ALBUM tags for dir and subdir without asking
• --compilation - skip the prompt about whether a compilation tag should be added, mark the album as a compilation
• --not-compilation - see above

• Fixing case-sensitivity for retrieving artist and album names from tags
• Showing covert art's size when listing
• Fixing main cover art for multi-CD albums (is copied to the main directory and therefore usually not found by players which are looking inside the final (ex. Disc 1 directory))
• Warning about potential non-allowed characters in filepaths (especially with Windows in mind)
• An option to download cover art (MusicBrainz? covers.musichoarders.xyz?)
• Marking the album as a compilation
• Queueing files as to not wait for conversions
