Installation

PyPI Installation

pip install image2sound-newrealm                # core only
pip install 'image2sound-newrealm[ui]'          # + Gradio UI
pip install 'image2sound-newrealm[opencv]'      # + OpenCV feature extraction
pip install 'image2sound-newrealm[audio]'       # + Soundfile output
pip install 'image2sound-newrealm[ml]'          # + scikit-learn clustering
pip install 'image2sound-newrealm[full]'        # all extras

Development Setup (Current)

# Clone the repository
git clone https://github.com/newrealmco/image2sound.git
cd image2sound

# Create virtual environment
python -m venv .venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate

# Install with UI support
pip install -e .[ui]

Quickstart

GUI (Recommended)

image2sound-ui

Opens a beautiful web interface in your browser where you can:

• Upload images with drag & drop
• Choose musical styles and settings
• Watch real-time generation progress
• Play generated music instantly
• Download files and open in file manager

Command Line

python -m image2sound.cli examples/demo.jpg -o out.wav --style ambient --duration 20

How it works

• Extract features: Brightness, contrast, edge density, and 5-color palette from image
• Map to music: Hue → key, brightness → BPM/scale, contrast+edges → intensity
• Compose arrangement: 4/4 time with chords, lead melody, bass, and drums
• Synthesize audio: Sine waves with harmonics and ADSR, drums as noise bursts

Styles

• neutral: Balanced mapping, piano/lead/drums
• ambient: Slower, major scale, soft pad/lead/bass instruments
• cinematic: Faster tempo, orchestral pad/lead/bass
• rock: Fastest, minor scale, piano/lead/drums with punch

Examples

# Basic usage
python -m image2sound.cli photo.jpg

# Custom style and duration
python -m image2sound.cli landscape.png --style cinematic --duration 30

# Output to specific file
python -m image2sound.cli portrait.jpg -o music.wav --style rock --duration 15

Batch demo

Generate a comprehensive demo set with musical metadata for analysis:

# Run batch processing on all images in examples/
python scripts/batch_demo.py

# Creates files like: bright_gradient_ambient_C_ionian_95bpm_4-4_I-V-vi-IV.wav
# Outputs CSV with: file,image,style,bpm,key,mode,meter,progression,seed,brightness,contrast,edge_density

The batch script processes all images in examples/ with each of the 4 styles (neutral, ambient, cinematic, rock), creating descriptive filenames that include the musical parameters and outputting detailed CSV metadata for analysis.
