TRUESTEN v 1.3

WHAT IS TRUESTEM?
-----------------
TRUESTEM is the first forensic audio tool that analyzes real physics of sound,
not metadata or tags. Detects AI where ears and other detectors fail.
Now with full SUNO v6 support - latest generation.

WHAT IT DETECTS?
----------------
- Suno v6 - LATEST + backward compatible v3/v4/v4.5/v5/v6
  (even with organic HF mimic - new gen Suno v6 faking organic roll-off)
- Udio, Stable Audio, MusicGen, Eleven Music
- Hybrids: human + AI mastering, AI mastering with human vocal
- Limiter signatures, loudness normalization, spectral flatness
- Timeline: 6-190s tracks

HOW IT WORKS?
-------------
1. MULTI-BAND SPECTRAL ANALYSIS - FFT 2048, Web Audio API - SUNO v6 READY
   - 4 bands: 2-8kHz (mids), 12-16kHz (Suno v6 plateau - key to v6!), 18-20kHz (HF sheen), flatness
   - Not single metric. Suno v6 has low 18-20k ratio but high absolute High 0.2-0.3
   - v1.3 adds: absolute HF bonus +12/+22/+30pts, ratio12 12-16kHz +15pts, flatness +10/+22/+10
   - Tuned specifically for Suno v6 organic mimic

2. TIMING ANALYSIS
   - Onset detection, micro-timing std
   - AI: <30ms too perfect, Human: 80-150ms natural drift
   - Final: 85% spectral + 15% timing

3. 100% OFFLINE - KEY DIFFERENCE
   - No file leaves your computer
   - Single HTML file, no cloud, no API, no upload
   - Works in Airplane Mode. Your tracks never hit a server.
   - Perfect for labels, Splice, Beatport - zero leaks

WHY DIFFERENT FROM OTHERS?
--------------------------
Other detectors (IRCAM etc):
- Based on metadata, require cloud upload
- Limit 1 file, subscription $20/mo
- Miss Suno v6 organic mimic (show HUMAN 22% on pure Suno v6)
- No batch, no CSV, no privacy

TRUESTEM v1.3 - SUNO v6 READY:
- Real physics, not metadata - detects Suno v6
- 100 files drag&drop batch
- Catches Suno v6 (test 4 files v4/v6: 22% HUMAN -> 66-92% AI LIKELY)
- One-time license, CSV export, 100% privacy
- 100% offline - your demo never goes to AI company

FOR WHOM?
---------
- Labels, A&R, Splice / Beatport / Spotify screening - Suno v6 filter
- Music publishers, libraries
- Producers: ghost production verification
- Artists: proof of humanity vs Suno v6
