PyKaraoke: The Open-Source Karaoke App for Linux, macOS & WindowsPyKaraoke is a lightweight, open-source karaoke player designed to run on Linux, macOS, and Windows. It focuses on playing karaoke files (audio plus lyrics) in a simple, dependable interface without the complexity of commercial karaoke systems. Because it’s cross-platform and community-driven, PyKaraoke is a good choice for hobbyists, small events, educators, and anyone who wants a free, privacy-respecting way to run karaoke from a laptop or desktop.
What PyKaraoke does well
- Plays common karaoke formats: PyKaraoke supports widely used lyric formats such as KAR (MIDI+lyrics) and LRC (time-synchronized plain-text lyrics).
- Cross-platform compatibility: Works on Linux, macOS, and Windows with minimal differences in core functionality.
- Simple UI for live use: The interface is straightforward — select a song, play/pause, and the synced lyrics display in a large readable font for singers.
- Open-source and extensible: The source code is available for inspection and modification, enabling users to fix bugs, add features, or tailor the app to specific needs.
Supported file types and formats
PyKaraoke primarily focuses on lyrics-synced files rather than complex multimedia packages. Typical supported types include:
- KAR — MIDI files with embedded lyrics (common in traditional karaoke collections).
- LRC — Plain-text lyric files with timestamps commonly used with MP3/FLAC audio.
- Plain text files and basic subtitle formats (support may vary by version).
If you have MP3 or other audio files that lack a synchronization file, you can create an LRC file to add time-synced lyrics.
Installation overview
Installation steps vary by platform. Below are general approaches; consult your distribution/package manager or the project’s repository for exact commands.
- Linux: Install via your distribution’s package manager if available (e.g., apt, dnf) or run from source using Python and pip. Dependencies often include Python, PyQt or GTK bindings, and audio backends.
- macOS: Use pip to install from source or run a packaged app if contributors provide one; Homebrew may host packages maintained by community members.
- Windows: Download an installer or run via Python; portability builds are sometimes available. Windows users may need to install additional audio libraries.
Example (source-based) installation pattern:
git clone https://example.org/pykaraoke.git cd pykaraoke pip install -r requirements.txt python run_pykaraoke.py Key features and user experience
- Lyrics display: Large, clear text with basic highlighting to follow the singer.
- Playlist support: Queue multiple songs for continuous play.
- Tempo and pitch controls: Some builds offer minor audio manipulation (availability depends on version).
- Fullscreen mode: Useful for projecting lyrics onto a TV or monitor during performances.
- Lightweight resource use: Suitable for older machines and Raspberry Pi–class devices.
Where PyKaraoke fits compared to other options
PyKaraoke shines when you want a no-frills, transparent, and modifiable karaoke player. It’s less suited for commercial venues that require advanced scoring, complex visualizations, or integrated video playback. For those use cases, dedicated commercial software or heavier open-source projects with multimedia engines may be better.
Common tasks and tips
- Creating LRC files: Use a simple text editor or one of many LRC editors to timestamp lyrics to the song. Matching timestamps precisely improves the sing-along experience.
- Projecting lyrics: Use fullscreen on a second display or a projector; choose a large, high-contrast font.
- Handling incompatible files: Convert unsupported audio formats (e.g., via ffmpeg) and add an LRC file for lyrics.
- Running on Raspberry Pi: Choose a lightweight desktop environment and ensure the audio backend is configured properly to avoid latency.
Troubleshooting checklist
- No sound: Verify system audio output and volume; test playback with a normal media player.
- Lyrics not syncing: Check the timestamps in the LRC file and ensure the audio file matches the one used when creating the LRC.
- Missing dependencies: Re-run installation steps and confirm Python and required GUI/audio bindings are installed.
- Crashes on startup: Run from a terminal to capture error messages; look for missing library errors or Unicode issues in lyric files.
How to contribute or extend PyKaraoke
- Report issues and request features on the project’s issue tracker.
- Submit pull requests with bug fixes or new features. Common contributions include improved format support (e.g., subtitle formats), better audio backend handling, theming, and usability improvements.
- Create plugins or forks for specialized use cases (K-8 school music classes, community centers, or party-focused visual skins).
Privacy and licensing
PyKaraoke’s open-source nature means you can inspect the source and run it locally without sending any data to third parties. Licensing depends on the project’s specific open-source license (check the repository’s LICENSE file); most community karaoke projects use permissive licenses like GPL or MIT.
Final thoughts
PyKaraoke is a practical, community-driven choice for anyone needing a simple karaoke solution across Linux, macOS, and Windows. It favors transparency and adaptability over flashy features, making it ideal for users who want control, lightweight performance, and the ability to customize or extend the app themselves.
