NeoMusic 🎵
A high-performance, cyberpunk-inspired Android music player built with a 100% custom Canvas-drawn UI. NeoMusic rejects standard UI kits in favor of a hand-crafted, neon-drenched aesthetic powered by Jetpack Compose.
✨ Key Features
- Hand-Crafted UI: Zero Material3 widgets. Everything from buttons to seek bars is drawn using the Compose Canvas API, featuring chamfered corners, neon glows, and custom gradients.
- Real-Time Spectrum Analyzer: A 16-band log-spaced FFT visualizer that reacts instantly to your music with smooth spring animations.
- Retro Hardware Controls: Interactive "Rotary Knobs" and "Retro Seek Bars" that mimic high-end analog audio equipment.
- Cyberpunk Aesthetics: A "Neo" theme utilizing over 30 custom neon color definitions and the TiltNeon display font.
- Modern Audio Engine: Powered by Media3 (ExoPlayer) with a custom
SpectrumAudioProcessorfor precise frequency analysis. - Lightweight & Fast: Efficient MediaStore indexing and optimized Canvas rendering ensure a lag-free experience even on older devices.
