OSMIX
Suno gives you stems. Osmix gives you a session.
SA9's Atomic music suite grew up. Osmix is one Rust engine across six surfaces: analyze (tempo, key, structure), separate (Demucs), classify per-onset drums, repair AI artifacts, extract MIDI, and master to EBU R128 — then write Reaper, Ableton, Logic, and Pro Tools sessions. Not a stub: real DSP, 185+ passing tests. The Atomic Sound / Video / Distro work SA9 pioneered is now Osmix's flagship engine.

CAPABILITIES
What OSMIX can do
Purpose-built capabilities engineered to deliver on every promise.
Separate
Canonical Demucs CLI source separation into vocals, drums, bass, and other.
Classify
Per-onset drum classification — kick, snare, hat, other — via spectral features.
Repair
De-reverb, phase coherence, and AI-artifact notching at Suno frequencies.
Extract
Spectral-flux onset + YIN pitch tracking into quantizable MIDI note events.
Master
EBU R128 LUFS matching + lookahead true-peak limiter, MP3 and WAV per preset.
OUR MISSION
One Rust engine. Six surfaces. Suno in, a real session out.
