+# Waveform Generator
+
+A standalone module for generating random procedural waveforms with various interpolation methods and smoothing techniques.
+
+## Features
+
+- **Multiple Interpolation Types**: Linear, exponential, logarithmic, and cubic curves
+- **Randomness Strategies**: Uniform, Gaussian, and smooth distributions
+- **Variable Resolution**: 8-64 control points for different levels of detail
+- **Smooth Rendering**: Anti-aliased curves with bezier interpolation
+- **Configurable Aesthetics**: Line width, colors, and smoothness controls
+
+## 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

+})
+```
+
+### Smooth Organic Curves
+```typescript
+const organic = generateWaveform({
+ splits: 24,
+ interpolation: 'cubic',
+ randomness: 'smooth',
+ smoothness: 0.7
+})
+```
+
+### Sharp Electronic Waveform
+```typescript
+const electronic = generateWaveform({
+ splits: 32,
+ interpolation: 'exponential',
+ randomness: 'uniform',
+ lineWidth: 1
+})
+```
+
+The generated waveforms are perfect for audio visualization and spectral synthesis applications.

-# 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)
