Biometric sound synthesis

Your body
becomes
sound.

Praenox reads your HRV, sleep architecture and stress — then generates a therapeutic soundscape engineered for your exact physiological state. Not generic. Not approximate. Yours.

01
Biometric input
Enter your daily HRV, resting HR, deep sleep %, REM %, stress score and sleep duration. The app builds a full physiological picture of your state and 7-day recovery trajectory.

02
Analysis engine
Praenox computes your recovery score, HRV velocity, sleep debt, and HRV spike classification. It selects a protocol — Maintenance, Delta, Cortisol, REM Restore, or Cardiac — and derives exact frequencies for your state.

Sound generation
A unique soundscape is synthesized: binaural beats, isochronic pulses, carrier tones, noise blends, breath guides, and ambient layers — all tuned to your exact biometric fingerprint and a dynamically built story arc.

⬡ Phase 2 — Coming

Control
before it
happens.

Phase 1 restores. Phase 2 predicts. Praenox will read your biometric trajectory and intervene before decline begins — adjusting soundscapes in real time as your body signals what's coming next, before you feel it.

Join the waitlist
Predictive intervention
HRV velocity and spike patterns identified 12–24 hours before physiological decline. Sound protocol adjusts before symptoms emerge.
Wearable live sync
Direct integration with your wearable — Praenox listens to your body in real time, not just after the fact. Dynamic soundscape morphing as biometrics shift.
Pre-emptive sound chamber
Not recovery. Not reaction. A continuous biometric-to-audio feedback loop that keeps you in a peak recovery corridor before you ever drop out of it.
In development — Phase 1 active since Feb 2026
