walrio 1.3.7

Modular audio library management system for playing, managing, and editing music files (requires FFmpeg, GStreamer, rsgain)

Walrio

Walrio is a modular library/set of files that let you play, manage, and edit music and music-related files. Every file should be usable via the terminal except documentation.

Contributing

For those interested in contributing code/documentation, please check the contribution guidelines. On top of these guidelines, this specific project requires a single comment at the top of each file explaining what it does so that help commands properlyload dynmically.

All current contributors are listed both in the sidebar and (optionally) in the AUTHORS file.

Licensing (USE IN OTHER PROJECTS)

Star History

File Structure

Modules

The main folder with all the seperate walrio music modules you can use and walrio.py, the global file that lets you easily run any file without having the CD into each folder. ⚠️ Important: Most processing is done where the command is called in a subfolder called "output_dir". If this is a folder containing any sensitive data please considr renaming it/moving it while doing any file processing.

Addons

Files that are non-essential for playing music but are still very nice to have/relevant for maintaining a music library (converter files, replay gain, move files, etc.). Can require modules from the addons folder itself or the core modules.

Core

The core set of modules that are absolutely essential to playing your music files from your media library. Often required for addons/niche modules to function.

Database

Modules that require a SQLite database (walrio_library.db/database.py from the core section) to function. These provide advanced library management features like playback statistics, smart playlists, and database-powered queues. The database must be created first using the database module.

Niche

Very specific workflow related files or extremely niche functionality. Generally files combining multiple different core and addon modules together into a singular unified workflow or something to connect your music to external programs/hardware.

Installation

Quick Install (pip)

pip install walrio

⚠️ Important: Walrio requires system dependencies that pip cannot install:

• FFmpeg
• GStreamer
• rsgain

After installing via pip, check for missing dependencies:

walrio dependency_checker --verbose

Then install any missing system packages (see System Requirements below).

If you have all the needed dependencies, you can get started using walrio with the help command (walrio --help).

System Requirements

Walrio requires the following non-Python tools to be installed on your system:

• FFmpeg - Audio/video conversion and processing (also used for album art resizing)
• GStreamer - Audio playback engine
• rsgain - ReplayGain 2.0 loudness scanner

Installation by platform:

Fedora:

sudo dnf install gstreamer1-plugins-base gstreamer1-plugins-good gstreamer1-plugins-ugly gstreamer1-tools ffmpeg rsgain

Ubuntu/Debian:

sudo apt install gstreamer1.0-tools gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-ugly ffmpeg
# rsgain: See https://github.com/complexlogic/rsgain

Arch Linux:

sudo pacman -S gstreamer gst-plugins-base gst-plugins-good gst-plugins-ugly ffmpeg
yay -S rsgain  # or use another AUR helper

macOS:

brew install gstreamer gst-plugins-base gst-plugins-good gst-plugins-ugly ffmpeg rsgain
