MIXI-CUTOpen-source DVS timecode for vinyl.

Generate. Decode. Cut. The timecode protocol designed for lathe-cut vinyl --- from protocol to platter.

3 kHz Stereo Quadrature

Dual-channel carrier with 90-degree phase offset. 2.5x resolution of Serato, instant direction detection, 0 ms re-lock after needle skip.

Dual-layer error protection. CRC-16 for O(1) fast-reject of corrupted frames, Reed-Solomon for full correction. Survives -24 dB SNR.

Frame acquisition in under 500 ms. Barker code autocorrelation guarantees sidelobe ratio of 1/13 --- no false lock.

500 Hz AM-modulated channel for instantaneous speed readout. Bypasses mass-spring damper latency --- instant scratch response.

Adaptive frame density --- 2x encoding rate on inner groove where linear velocity drops. Compensates for reduced SNR automatically.

Python, C, Rust, JavaScript. Every decoder is open source, tested, and production-ready. No vendor lock-in, no DRM, MIT license.
