Astra - Audiophile music player with real-time DSP and EQ controls

Astra - Audiophile music player with real-time DSP and EQ controls by Razvan Serea Astra is an audiophile music player designed for local music libraries, supporting MP3, FLAC, WAV, AAC, OGG, M4A, OPUS, WMA, AIFF, and more via FFmpeg. It offers gapless playback with pre-buffering, multichannel audio remapping, and Dolby Atmos decoding, ensuring albums play seamlessly while maintaining high-fidelity sound. Astra features real-time DSP visualizers powered by a native C++ engine, including an oscilloscope, spectrum analyzer, and vectorscope. A fully parametric 10-band EQ with live frequency response, built-in presets, and AutoEQ headphone calibration import lets you precisely shape your sound. Playback controls include shuffle, repeat, and drag-and-drop queue management, while the library automatically extracts metadata, album artwork, and supports global search, favorites, and recently played tracking. Additional features include output device selection, delay calibration, customizable themes, fullscreen and mini-player modes, Discord Rich Presence, optional Last.fm scrobbling, and an opt-in local API for integrations. Astra delivers a complete, high-quality desktop audio experience with no telemetry, accounts, or streaming.
