Retro Mix 💽

Retro Mix is a dedicated offline, high-fidelity audio workstation and vintage turntable player engineered for purists who demand studio-grade, bit-perfect local audio reproduction without streaming compression, telemetry, or system bloat.

Built from the ground up in pure Java using low-level Digital Signal Processing (DSP) and custom 2D hardware-accelerated vector graphics, Retro Mix merges the warmth of analog crate digging with precision modern audio mixing.
