+
+## Project Overview
+
+CoolSoup is a React + TypeScript + Vite application that generates visual patterns and converts them to audio through spectral synthesis. The app features multiple image generators (Tixy expressions, geometric tiles, external APIs) and an advanced audio synthesis engine that treats images as spectrograms.
+
+## Development Commands
+
+- `pnpm dev` - Start development server with hot reload
+- `pnpm build` - Build for production (TypeScript compilation + Vite build)
+- `pnpm lint` - Run ESLint on the codebase
+- `pnpm preview` - Preview production build locally
+
+## Architecture Overview
+
+### Core Application Structure
+- **State Management**: Uses Nanostores for reactive state with persistent atoms
+- **UI Layout**: Two-panel design - main content area (generator + image grid) and collapsible audio panel
+- **Generator Pattern**: Pluggable generator system where each generator implements a common interface
+
+### Main Store (`src/stores/index.ts`)
+Central state management with these key atoms:
+- `appSettings` - Generator selection, grid size, colors
+- `generatedImages` - Array of generated images with metadata
+- `selectedImage` - Current image for audio synthesis
+- `synthesisParams` - Audio synthesis configuration
+- `panelOpen` - Audio panel visibility
+
+### Generator System
+Four built-in generators located in `src/generators/`:
+- **Tixy** (`tixy.ts`) - Mathematical expressions using t,i,x,y variables
+- **Waveform** (`waveform.ts`) - Procedural random waveforms with various interpolation curves
+- **Picsum** (`picsum.ts`) - External random images API
+- **Art Institute** (`art-institute.ts`) - Art Institute of Chicago API
+
+Each generator returns `GeneratedImage[]` with:
+- `id` - Unique identifier
+- `canvas` - HTMLCanvasElement
+- `imageData` - ImageData for synthesis
+- `generator` - Generator type
+- `params` - Generation parameters
+
+### Spectral Synthesis Engine (`src/spectral-synthesis/`)
+Advanced image-to-audio synthesis library:
+- **Core Logic** (`core/synthesizer.ts`) - Main ImageToAudioSynthesizer class
+- **Types** (`core/types.ts`) - SynthesisParams and related interfaces
+- **Audio Export** (`audio/export.ts`) - WAV file generation and download
+- **Utilities** (`core/utils.ts`) - Helper functions for frequency mapping and peak detection
+
+Key features:
+- Mel-scale frequency mapping for perceptual accuracy
+- Spectral peak detection to reduce noise
+- Temporal smoothing for coherent audio trajectories
+- Auto-detection of image type (spectrogram vs diagram)
+- Configurable synthesis parameters (duration, frequency range, resolution)
+
+### Audio Export System (`src/audio-export/`)
+Batch audio processing capabilities:
+- Single image export with custom parameters
+- Batch export of all generated images
+- ZIP file generation for batch downloads
+- Progress tracking for long operations
+
+## Key Implementation Details
+
+### Image Generation Flow
+1. User selects generator and parameters in `GeneratorSelector`
+2. `App.tsx` calls appropriate generator function
+3. Generator returns array of `GeneratedImage` objects
+4. Images displayed in `ImageGrid` component
+5. User can click image to select for audio synthesis
+
+### Audio Synthesis Flow
+1. User selects image from grid (sets `selectedImage`)
+2. `AudioPanel` provides synthesis parameter controls
+3. Synthesis triggered via spectral-synthesis library
+4. Audio can be played directly or exported as WAV
+5. Batch export processes all generated images
+
+### Component Architecture
+- **App.tsx** - Main layout and generation orchestration
+- **GeneratorSelector** - Generator picker with settings
+- **ImageGrid** - Grid display of generated images
+- **AudioPanel** - Audio synthesis controls and export
+- **AudioControls** - Playback controls for generated audio
+
+## Generator Module Structure
+Both tixy-generator and waveform-generator modules are designed as standalone packages:
+
+**Tixy Generator**:
+- `README.md` - Documentation and usage examples
+- `core/types.ts` - Type definitions
+- `index.ts` - Main exports
+- Generator-specific files (evaluator, patterns, etc.)
+
+**Waveform Generator**:
+- `README.md` - Documentation and usage examples
+- `core/types.ts` - Interfaces and configuration
+- `core/interpolation.ts` - Curve interpolation functions (linear, exponential, logarithmic, cubic)
+- `core/generator.ts` - Control point generation and randomness strategies
+- `renderer/canvas.ts` - Canvas rendering with smooth anti-aliased curves
+- `index.ts` - Main exports and convenience functions
+
+## Development Notes
+- Uses Rolldown Vite for improved performance
+- Tailwind CSS for styling (no rounded corners per user preference)
+- ESLint configured for React + TypeScript
+- All generators support time-based animation parameters
+- Image synthesis supports real-time parameter adjustment

+## Quick Start
+
+```typescript
+import { generateRandomWaveform } from './waveform-generator'
+
+// Generate a single random waveform
+const waveform = generateRandomWaveform()
+document.body.appendChild(waveform.canvas)
+
+// Generate with custom configuration
+const customWaveform = generateWaveform({
+  splits: 32,
+  interpolation: 'cubic',
+  randomness: 'smooth',
+  lineWidth: 3
+})
+```
+
+## API Reference
+
+### Main Functions
+
+#### `generateWaveform(config?)`
+Generate a waveform with optional configuration override.
+
+#### `generateRandomWaveform()`
+Generate a waveform with randomized parameters for maximum variety.
+
+#### `generateWaveformBatch(count)`
+Generate multiple random waveforms efficiently.
+
+### Configuration
+
+```typescript
+interface WaveformConfig {
+  width: number              // Canvas width (default: 256)
+  height: number             // Canvas height (default: 256)
+  splits: number             // Number of control points (8-64)
+  interpolation: InterpolationType  // Curve type
+  randomness: RandomnessStrategy    // Distribution strategy
+  lineWidth: number          // Stroke width (1-4)
+  backgroundColor: string    // Background color
+  lineColor: string         // Line color
+  smoothness: number        // Curve smoothness (0-1)
+}
+```
+
+### Interpolation Types
+
+- **Linear**: Straight lines between points
+- **Exponential**: Accelerating curves (slow → fast)
+- **Logarithmic**: Decelerating curves (fast → slow)
+- **Cubic**: Smooth bezier-like curves
+
+### Randomness Strategies
+
+- **Uniform**: Pure random distribution (maximum variation)
+- **Gaussian**: Bell-curve distribution (center-biased)
+- **Smooth**: Smoothed random with edge tapering
+
+## Algorithm
+
+1. **Control Point Generation**: Create evenly-spaced X coordinates with random Y values
+2. **Randomness Application**: Apply distribution strategy (uniform/gaussian/smooth)
+3. **Smoothing**: Optional smoothing and tension application
+4. **Interpolation**: Generate curve points between control points
+5. **Rendering**: Draw smooth anti-aliased curves to canvas

-# Geometric Tiles Generator
-
-A standalone package for generating geometric tile patterns in black and white. Similar to Tixy but focused on classic geometric and algorithmic patterns.
-
-## Features
-
-- 20 built-in geometric patterns
-- Tile-based rendering system
-- Configurable tile size and colors
-- Standalone, reusable package
-
-## Patterns
-
-- **Checkerboard**: Classic alternating squares
-- **Stripes**: Horizontal and vertical lines
-- **Diagonal**: Diagonal line patterns
-- **Diamond**: Diamond grid patterns
-- **Cross**: Plus/cross intersections
-- **Maze**: Maze-like corridors
-- **Triangles**: Triangular tessellations
-- **Hexagon**: Hexagonal patterns
-- **Waves**: Sine wave based patterns
-- **Spiral**: Spiral arm patterns
-- **Concentric**: Concentric circle rings
-- **Bricks**: Brick wall patterns
-- **Dots**: Regular dot grids
-- **Zigzag**: Zigzag patterns
-- **Random**: Pseudo-random noise
-- **Voronoi**: Cell-like patterns
-- **Fractal**: Sierpinski-like fractals
-- **Complex Maze**: Procedural maze generation
-
-## Usage
-
-```typescript
-import { GEOMETRIC_PATTERNS, renderTilesToCanvas } from './geometric-tiles'
-
-// Get a pattern
-const checkerboard = GEOMETRIC_PATTERNS.checker
-
-// Render to canvas
-const result = renderTilesToCanvas(checkerboard, {
-  width: 512,
-  height: 512,
-  tileSize: 8,
-  time: 0,
-  backgroundColor: '#000000',
-  foregroundColor: '#ffffff'
-})
-
-// Use the canvas
-document.body.appendChild(result.canvas)
-```
-
-## API
-
-### TileExpression
-- `name`: Human-readable pattern name
-- `code`: String representation of the pattern logic
-- `compiled`: Function that generates the pattern
-
-### TileRenderOptions
-- `width`: Canvas width in pixels
-- `height`: Canvas height in pixels
-- `tileSize`: Size of each tile in pixels
-- `time`: Time parameter (for animated patterns)
-- `backgroundColor`: Background color (hex)
-- `foregroundColor`: Foreground color (hex)
-
-The tile function receives: `(x, y, i, t, size)` where:
-- `x, y`: Tile coordinates
-- `i`: Linear tile index
-- `t`: Time parameter
-- `size`: Grid size (max of width/height in tiles)
