Troubleshooting PyKaraoke: Common Issues and Quick Fixes

Getting Started with PyKaraoke — Installation, Features, and TipsPyKaraoke is an open-source karaoke player written in Python that supports multiple lyric formats, audio playback, and a simple user interface suitable for casual singing sessions, home parties, or small events. This guide walks you through installation, core features, configuration tips, and troubleshooting so you can get singing quickly.

What is PyKaraoke?

PyKaraoke is a lightweight, cross-platform karaoke application that plays audio files alongside synchronized lyrics. It supports common lyric formats like KAR, LRC, and CDG, and can play standard audio formats (MP3, WAV, OGG, etc.). Because it’s Python-based and open-source, it’s a good choice if you want something simple, customizable, and free.

System requirements

A computer running Windows, macOS, or Linux
Python 3.6+ (for source installation) — many distributions include a packaged version that bundles dependencies
Audio output device (speakers, AUX, Bluetooth)
Optional: external microphone and sound mixer for live vocals

Installation

Below are several methods to install PyKaraoke depending on your platform and preference.

1) Install from package manager (Linux)

On Debian/Ubuntu-based systems, PyKaraoke may be available via apt. Update package lists and install:

sudo apt update sudo apt install pykaraoke

On Fedora or other RPM-based distributions, check your package repositories or use Fedora’s package manager:

sudo dnf install pykaraoke

If your distribution doesn’t include a package, use one of the source-based methods below.

2) Install via pip (source-based)

If a packaged version isn’t available, install from PyPI (if published) or from source. First ensure Python 3 and pip are installed:

python3 -m pip install --user --upgrade pip setuptools wheel

Then install PyKaraoke:

python3 -m pip install --user pykaraoke

If the project isn’t on PyPI, clone the repository and install:

git clone https://github.com/pykaraoke/pykaraoke.git cd pykaraoke python3 -m pip install --user .

3) Windows installation

If packaged as an installer, download the Windows installer from the project’s releases page and run it.
Or use pip in Command Prompt/PowerShell:

python -m pip install pykaraoke

Make sure Python is added to PATH.

4) macOS

Use Homebrew if a formula exists, or install via pip as above.
You may need to grant microphone/sound permissions when running.

First run and basic workflow

Launch PyKaraoke from your applications menu or run pykaraoke from the terminal/command prompt.
Add your music and lyric files: most users place media and corresponding lyric files in the same folder. PyKaraoke will scan and list tracks.
Select a track — the player shows synchronized lyrics and playback controls (play/pause/seek).
Adjust audio output device and volume. If using a mic, configure input and mixing externally or via the OS sound settings.

Supported formats

Karaoke: KAR (MIDI with lyrics), CDG (MP3+CDG), LRC (timestamped lyrics)
Audio: MP3, WAV, OGG, FLAC (format support depends on installed audio backends)
Playlist: M3U, simple directory scanning

Key features

Synchronized lyric display with scrolling and highlighting
Playlist support and track queuing
Adjustable font size, colors, and display layout (depends on version)
Basic search and library organization
MIDI/KAR playback (if MIDI backend available)
Lightweight UI with low resource usage

Configuration and customization

Theme and appearance: Some versions allow changing font, size, and colors via preferences or configuration files. Look for a settings menu or edit a config file (often in ~/.config/pykaraoke or similar).
Hotkeys: Configure or learn keyboard shortcuts for playback, seeking, and toggling fullscreen.
Display output: For external displays (projector/TV), set PyKaraoke to fullscreen on the desired monitor or extend your desktop and drag the window.
Microphone input: PyKaraoke generally handles playback only; mix live mic input through your OS sound settings or a hardware mixer so vocals go to your speakers while the app plays tracks.

Tips for best experience

Keep audio and lyric files together and named consistently (e.g., “Song Title.mp3” and “Song Title.lrc”) for automatic pairing.
Use high-quality audio files and an audio interface if you need low latency and good mic mixing.
Pre-create playlists for parties and use the queue feature to manage requests.
For large screens, increase font size in settings or use fullscreen mode.
Test MIDI/KAR files beforehand—MIDI playback depends on available synthesizer/backends.

Common issues & troubleshooting

No audio: check system volume, output device, and whether another app is blocking audio. Verify codecs are installed (e.g., MP3).
Lyrics not showing: confirm lyric file exists and is formatted correctly (LRC timestamps, KAR pairing). Rename files to match if needed.
MIDI/KAR playback problems: ensure a MIDI synthesizer or Timidity++ is installed and configured.
Crashes on startup: run from terminal to see error messages, check dependencies, and update Python packages.
