Free and open source (FOSS) Qobuz client for Linux with native, high-fidelity playback. QBZ-NIX removes browser sample-rate limits and delivers hi-res audio through a purpose-built Rust playback engine.

Why QBZ-NIX

Browsers cap audio output around 48 kHz, while Qobuz streams up to 192 kHz. QBZ-NIX uses a native playback pipeline so your system and DAC can receive the original resolution, with proper device control, caching, and media integration.

Features

Streaming and Playback

Qobuz authentication and full catalog search (albums, tracks, artists, playlists).
Native decoding for FLAC and MP3 with real-time playback state updates.
Quality selection with automatic fallback across Qobuz tiers.
Audio device enumeration and per-device output selection.
Gapless-ready playback pipeline with precise position tracking.

Queue and Library

Queue management with shuffle, repeat, and history navigation.
In-memory audio cache with LRU eviction and next-track prefetching.
Favorites and playlists from your Qobuz account.
Local library backend: directory scanning, metadata extraction, CUE sheet parsing, and SQLite indexing.

Integrations

MPRIS media controls and media key support on Linux.
Desktop notifications for track changes.
Last.fm scrobbling and now-playing updates.
Shareable Qobuz URLs and universal SongLink links (Odesli).

Interface

Now playing, queue panel, and full-screen playback views.
Focus mode for distraction-free listening.
English and Spanish localization.

Open Source

QBZ-NIX is MIT-licensed and fully open source. No telemetry, no lock-in, and no hidden services. Just a clean, transparent player built for Linux audio fans.

Inspiration

QBZ-NIX draws inspiration from projects like qobuz-dl, and from the broader Linux audio community that values open tools and high-fidelity playback.
