The Hybrid Production Standard (HPS-1.0) — Technical Specification & Executive Takeaway

Three Essential Stakeholders

Built for Artists, Distributors, & Platforms Alike

HPS bridges the divide between independent creators, distributor ingest pipelines, and global streaming platforms.

For Artists & Advocates

Elevating Human Craftsmanship

Provides positive proof of human composition and tracking. Protects independent creators from false AI takedowns while giving hybrid artists a proud, transparent label.

For Distributors (DistroKid, FUGA, Believe)

Zero-Friction Fraud Defense

Replaces unverified checkboxes with tamper-evident audio essence hashes (`raw_audio_essence`). Maps 1-to-1 into existing DDEX ERN 4.3 delivery feeds.

For DSPs (Spotify, Apple, YouTube)

Audit-Ready Legal Compliance

Fully satisfies EU AI Act Article 50 disclosure mandates. Surfaces clear Transparency Badges (`[HPS-X1]`) and credits without flattening creative context.

The Industry Gap

Binary labels collapse process into a single bit.

A single "Was AI used?" checkbox creates two major failure modes across the industry today:

Failure Mode A — Over-Flagging

A songwriter tracks acoustic drums and vocals live, then runs an AI mastering plugin. They receive the exact same binary "AI" flag as a 10-second prompt generator.

Penalizes standard studio tools

Failure Mode B — Erasure of Craft

A producer spends 40 hours re-pitching, re-arranging, stem-separating, and re-performing an AI vocal seed. They are forced to hide their process or get branded as automated junk.

Erases human artistry

HPS does not ask "did you use AI." It evaluates who made the creative decisions at each stage — classifying the process, not the tool.

Core Standard

The Five Axes of Music Production

Every work is scored across five core production stages as H (Human), A (AI), or H+A (Hybrid / Co-Creative):

Axis
Production Stage
Key Question

01. Origination

Composition & Writing

Where did the core idea come from — melody, chords, lyrics, or structural seed?

02. Performance

Tracking & Vocal Execution

Who performed the final vocal, instrument, or MIDI performance in the master?

03. Curation

Editing & Arrangement

Who selected, chopped, re-arranged, and sequenced stems into the final structure?

04. Sound Source

Timbre & Synthesis

Is the raw audio source a physical instrument/voice, or an AI synth model?

05. Post-Production

Mixing & Mastering

Who executed mixing, equalization, dynamic processing, and final mastering?

HPS Live Tag Builder

HPSX1

Human-Led Hybrid

Human origination and performance. AI confined to sound design, texture, or mastering.

HPS: X1 [Origination: H, Performance: H, Curation: H, Sound: H, Post: H]

Classification Matrix

Three Tiers. The Hybrid Gradient is the Point.

Tier H — Human

Origination and performance are both human. Minimum 4 of 5 axes human. AI, if present, is restricted to post utility or corrective plugins.

Tier X — Hybrid

Primary human creative authorship on origination or performance with AI contribution on complementary axes.

X1 Human-Led — AI used for texture, sound design, or mastering only

X2 Co-Creative — Human & AI co-compose/sing; human retains edit control

X3 AI-Led — AI origination/synth; human substantially re-arranges & transforms

X4 Curated — AI origination/performance; human selects and lightly edits

Tier A — AI

Origination and performance are both AI-generated. Human input limited to text prompting and selection without structural rework.

Distributor Portal

Zero-Friction Ingest & Fraud Protection for Distributors

Distributors (DistroKid, TuneCore, FUGA, Believe) can adopt HPS in three seamless phases without rebuilding ingestion pipelines.

PHASE 1 · ZERO BUILD

Structured 5-Axis Self-Report

Replace flat AI checkboxes in upload forms with 5-axis dropdowns. Automatically maps directly to standard DDEX ERN 4.3 XML AI fields.

PHASE 2 · OPTIONAL PROOF

Cryptographic Essence Signing

Artists generate Ed25519-signed `hps_manifest.json` via HPS CLI or DAW plugin. Ingestion server verifies raw PCM SHA-256 hash on drop.

PHASE 3 · AUTOMATED PIPELINE

Verified Source of Truth

Signed manifest populates all release delivery metadata. Surfaces verified `[HPS-X1]` badges directly on streaming partner UIs.

Raw PCM Essence Hashing (`raw_audio_essence`)

HPS hashes decoded PCM audio samples, ignoring container headers. If ID3 tags are altered or format converted, the essence hash remains valid. If audio samples are edited, the hash invalidates automatically.

Distributor Verification API Spec

POST https://api.trustnodelogic.com/v1/verify

Submits file or manifest. Returns boolean verification, essence hash match status, and Ed25519 signature validity.

DSP Specification

DSP Badging & Metadata Guidelines (Spotify, Apple Music)

HPS specifies how streaming platforms display transparency badges and credits without cluttering UI design:

UI Badging Standards

        [HPS-H] Human Produced
        [HPS-X1] Human-Led Hybrid
        [HPS-X2] Co-Creative Hybrid
        [HPS-A] Synthetic AI
      

Clicking any badge reveals full 5-axis process credits (e.g., Vocals: Human, Master: AI Assist, Composition: Human).

Regulatory Compliance

EU AI Act Article 50 Legal Compliance Matrix

EU Provision

Article 50 Binary Mandate

HPS-1.0 Technical Standard

Article 50(2) Provider Marking

Machine-readable flag for synthetic audio.

Full Tier A & X4 cryptographic manifest integration.

Article 50(4) Deployer Disclosure

Disclose artificially generated/manipulated content.

Granular 5-axis role breakdown (e.g., AI vocal vs AI master).

Article 50 Exemptions

Artistic/Creative assistance exemptions.

Tier H & X1 provide verifiable positive proof of human craft.

The standard that ends the "AI vs. Human" culture war.
