ToneForge Compiler is the missing “linker” layer that turns ToneForge from a powerful authoring system into a ship‑ready production platform. Below is a complete, standalone PRD that positions it cleanly in the architecture without overlapping Runtime, Integrations, or CLI.

🧱 ToneForge Compiler

Product Requirements Document (PRD)

1. Product Overview

Product Name

ToneForge Compiler

Description

ToneForge Compiler is the build, optimization, and packaging module of the ToneForge ecosystem. It transforms curated procedural sound and visual behaviors into platform‑specific, production‑ready artifacts, deciding what remains procedural, what gets baked, and how assets are bundled for shipping.

ToneForge Compiler does not generate sound or visuals.
It decides how ToneForge content becomes deliverable assets.

2. Role in the ToneForge Ecosystem

ToneForge Compiler sits between Library curation and Integration / Shipping:

Library → Compiler → Integrations → Engine / Runtime
              ↑
         Intelligence

Its purpose is to:

  • optimize procedural systems for deployment
  • reduce runtime cost
  • enforce platform constraints
  • produce deterministic build artifacts
  • formalize the “shipping” step of ToneForge

3. Design Goals

Primary Goals

  • Deterministic, reproducible builds
  • Platform‑aware optimization
  • Explicit procedural vs baked decisions
  • CI‑friendly execution
  • Transparent, inspectable output

Non‑Goals

  • Runtime playback
  • Asset authoring
  • AI inference
  • Manual editing

4. Core Responsibilities

ToneForge Compiler handles:

  • Procedural → baked decision‑making
  • Asset bundling and packaging
  • Platform‑specific constraints
  • Dependency resolution
  • Build validation
  • Output manifest generation

It does not:

  • modify creative intent
  • alter sound behavior
  • make irreversible decisions without configuration

5. Compilation Inputs

ToneForge Compiler consumes:

  • ToneForge Library entries
  • Stack definitions
  • Sequencer patterns
  • Visualizer recipes
  • Context and State references
  • Platform target configuration
  • Compiler ruleset

6. Compilation Outputs

Depending on configuration, outputs may include:

  • WAV / OGG / MP3 assets
  • Sprite sheets / VFX textures
  • Procedural presets
  • Runtime manifests
  • Dependency graphs
  • Validation reports

All outputs are versioned and deterministic.

7. Procedural vs Baked Decision Model

Compiler decides per asset:

Option Use Case
Procedural High repetition, low cost
Hybrid Procedural core + baked layers
Fully Baked Cinematic, performance‑critical

Decisions are:

  • rule‑driven
  • overrideable
  • explainable

8. Platform Targeting

Compiler supports multiple targets:

  • Web
  • Mobile
  • Console
  • Desktop
  • Low‑power / accessibility modes

Each target defines:

  • CPU budget
  • memory limits
  • audio format constraints
  • visual complexity limits

9. Compiler Ruleset

Rules are declarative and human‑readable:

{
  "target": "mobile",
  "maxVoices": 16,
  "bake": {
    "category": ["explosion", "cinematic"],
    "durationAbove": 2.0
  }
}

Rulesets can be:

  • project‑specific
  • platform‑specific
  • CI‑enforced

10. Intelligence Integration

ToneForge Intelligence can:

  • suggest bake thresholds
  • detect over‑proceduralization
  • flag redundant assets
  • recommend optimization strategies

Compiler never auto‑accepts Intelligence suggestions without approval.

11. Validation & Safety

Compiler validates:

  • loudness compliance
  • duration bounds
  • missing dependencies
  • platform constraints
  • determinism guarantees

Failures are explicit and build‑blocking when configured.

12. Build Manifests

Every compile produces a manifest:

{
  "buildId": "tfc_2026_02_20",
  "target": "web",
  "proceduralAssets": 42,
  "bakedAssets": 128,
  "hash": "a9f3c2"
}

This ensures:

  • traceability
  • reproducibility
  • auditability

13. CLI & Automation

ToneForge Compiler is primarily invoked via CLI:

toneforge compile \
  --target web \
  --library combat \
  --rules mobile.json

Designed for:

  • CI/CD
  • headless builds
  • incremental compilation

14. Performance Targets

  • Incremental builds where possible
  • Parallelizable compilation
  • Predictable memory usage
  • Scales to large libraries

15. Debugging & Tooling

Optional tooling includes:

  • dry‑run compilation
  • diff between builds
  • asset size breakdowns
  • procedural vs baked visualization

16. Future Extensions

  • Cloud‑based compilation
  • Build caching
  • Cross‑project dependency reuse
  • Marketplace‑aware packaging
  • Runtime hot‑swap support

17. Why ToneForge Compiler Matters

Without a compiler:

  • procedural systems remain theoretical
  • shipping becomes manual
  • performance tuning is ad‑hoc

ToneForge Compiler turns procedural intent into production reality.

18. Summary

ToneForge Compiler is the final transformation layer of the ToneForge ecosystem.
It bridges creative procedural systems and real‑world deployment by compiling sound and visual behavior into optimized, deterministic, platform‑ready assets.

It is the difference between having a powerful system and shipping with confidence.

If you want next, the strongest follow‑ups are:

  • a Compiler + Runtime interaction spec
  • example compiler rulesets for different platforms
  • or a comparison to traditional audio middleware build pipelines
