Aqloss

A cross-platform music player engineered for bit-perfect, lossless, and hi-res audio playback - on every device you own.

---

Why Aqloss?

Most music players resample, normalize, or quietly degrade your audio before it reaches your ears. Aqloss does not. It decodes your files exactly as they were recorded and sends them to your hardware without touching a single sample.

• Bit-perfect output - WASAPI Exclusive (Windows), CoreAudio (macOS/iOS), PipeWire/ALSA (Linux), AAudio (Android)
• Hi-res support - up to 32-bit / 384kHz
• True lossless formats - FLAC, WAV, AIFF, ALAC, DSD (DSF/DFF)
• One codebase - Flutter UI runs natively on all 5 platforms
• Rust audio engine - high-performance, memory-safe, zero compromises
