Felicity is the third and final app in a series of three planned projects for learning purposes, following Positional and Inure App Manager. Time is being taken to ensure the app exceeds expectations in software quality. Patience is appreciated until the first results emerge. The project uses the codename Felicity, with the final name subject to future updates. Features Custom Audio Engine - Dual decoder utilizing both hardware and software decoding through FFmpeg. - Custom DSP: The entire audio processing chain (EQ, bass, reverb) is written in C++ via JNI. It utilizes ARM NEON SIMD auto-vectorization to process audio arrays with absolute minimum CPU overhead. - Supports bass, treble, and more. - Native downmixing support to pass multichannel audio to stereo output. - Advanced effects: Integrated spatial effects including stereo widening and tape saturation for an analog feel. - 10-band equalizer: A powerful equalizer with 10 adjustable frequency bands up to +/-15 dB, with dedicated preamp support. - Gapless playback: Seamless transitions between tracks without gaps or interruptions. - High-resolution audio support: Support for high-resolution audio formats such as FLAC, ALAC, and DSD for audiophile-grade sound quality. - Multi-channel audio support: Support for multichannel audio formats like 5.1 and 7.1 surround sound for an immersive listening experience. User Interface - Fully custom-built and highly optimized interface inspired by Inure App Manager. - Dynamic theming: The app's theme dynamically adapts to the album art of the currently playing track, creating a visually cohesive and immersive experience. - Custom animations: Smooth and visually appealing animations throughout the app, enhancing the user experience and making interactions more engaging. - Themes: Multiple themes including light, dark, AMOLED black, Material You, and others. - Core: Predictive back, edge-to-edge, and adapted to all modern Android UI features. - Embedded lyrics: Reliable, on-the-fly LRC extraction and support for online downloading from LrcLib. - Dual fast scroll: Simultaneous support for both slide-to-scroll and jump-to-letter fast scroll. - Realtime audio visualizer: A lock-free, zero-allocation visualizer rendering on the Canvas at native FPS, powered by a native PFFFT implementation. Library Management - Realtime library updates: The app automatically detects and updates the music library in real-time as new tracks are added or removed from the device (adapted from Peristyle app). - All storage support: Full support for both internal and external storage, including SD cards and USB drives. - Auto scanning: The app automatically scans for new music files and updates the library without requiring manual refreshes. Smart Core - True randomized shuffle: Choose between Miller and Fisher-Yates shuffle algorithms. This feature list is not exhaustive; only the main features are listed.
