A modern, feature-packed internet radio player built with JavaFX. Search thousands of stations worldwide, save your favorites, and enjoy synced audio visualizations — all without any external dependencies.
Version 2.0 is a complete rewrite of the audio engine. VLC is no longer required. The app now uses pure Java audio decoding, which means users just download and run — no extra installs needed.
Other improvements include DNS-based server discovery for the Radio Browser API (automatically finds working servers), a synced FFT visualizer that feeds directly from the audio stream instead of capturing from the microphone, proper thread management, and URL-encoded search queries.
Global Search — Find stations worldwide using the Radio Browser API with automatic server failover. Results are sorted by popularity and show codec info.
Favorites — Save, organize, and quickly access your favorite stations. Stored locally in a simple text file.
Audio Playback — Supports MP3, AAC, WAV, OGG Vorbis, and FLAC streams through pure Java decoders. No VLC, no GStreamer, no native installs.
Synced Visualizer — Real-time FFT bar visualizer that reads directly from the audio stream. Hanning window, logarithmic amplitude scaling, and frequency boosting for a balanced display.
Volume Control — Synced sliders across Search and Favorites tabs with real-time PCM volume scaling.
Dark Theme — Eye-friendly dark interface for comfortable listening.
Built-in Clock — Digital clock display in the status bar.
Java 21 or newer. That's it.

JavaFX 21 for the UI, Java Sound SPI with mp3spi, JOrbis (OGG), and JFlac (FLAC) for audio decoding, JTransforms for FFT, Jackson for JSON parsing, and Ikonli for icons. All dependencies are managed through Maven and bundled automatically.
Contributions are welcome. Some areas that could use work:
- Visualizer improvements (different modes, smoother animations)
- Station metadata display (bitrate, genre, country)
- Playlist/queue support
- Equalizer
- System tray integration
