## Overview

This directory contains comprehensive documentation, resources, and implementation guides for integrating **Pedalboard** (Spotify's Audio Processing Library) with GNN (Generalized Notation Notation). Pedalboard provides high-performance DSP capabilities, VST3/AU plugin ecosystem, and Python-native API for sophisticated audio representations and real-time sonification of Active Inference models.

**Status**: ✅ Documentation Module  
**Version**: 1.0  

---

## Purpose

Pedalboard integration enables:

- **Model Sonification**: Auditory representation of Active Inference models
- **Real-Time Audio**: Real-time sonification of model dynamics
- **Audio Analysis**: Audio-based model analysis and debugging
- **Professional Quality**: High-quality audio processing for research and presentation
- **VST3/AU Plugin Support**: Professional audio plugin ecosystem integration

## Documentation Structure

This module is organized as follows:

- **Overview**: High-level description and purpose
- **Contents**: Files and subdirectories
- **Integration**: Connection to the broader pipeline
- **Usage**: How to work with this subsystem

## Integration with Pipeline

This documentation is integrated with the 25-step GNN processing pipeline:

### Core Processing (Steps 0-9)
- **Step 3 (GNN)**: Pedalboard audio generation from parsed GNN models
- **Step 7 (Export)**: Audio parameter mapping in export formats

### Simulation (Steps 10-16)
- **Step 15 (Audio)**: Real-time sonification using Pedalboard
- **Step 16 (Analysis)**: Audio-based model analysis

### Integration (Steps 17-24)
- **Step 20 (Website)**: Audio visualization integration
- **Step 23 (Report)**: Audio analysis results in reports

See [src/gnn/AGENTS.md](../../src/gnn/AGENTS.md) for complete pipeline documentation.

## Function Signatures and API

> ⚠️ **Planned / Not Yet Implemented**: `src/gnn/audio/pedalboard/` is currently a scaffold only (no `.py` source). The signatures below are planned and do not describe shipped functions.

### Audio Processing Functions

```python
def generate_audio_from_gnn(gnn_model: GNNModel, audio_params: dict) -> AudioFile:
    """
    Generate audio representation from GNN model using Pedalboard.

    Parameters:
        gnn_model: Parsed GNN model structure
        audio_params: Audio generation parameters

    Returns:
        AudioFile with sonified model representation
    """


def apply_audio_effects(audio: AudioFile, effects: List[Plugin]) -> AudioFile:
    """
    Apply Pedalboard audio effects to generated audio.

    Parameters:
        audio: Input audio file
        effects: List of Pedalboard plugins to apply

    Returns:
        Processed AudioFile with effects applied
    """
```
