Oculizer 🎵 💡

Originally developed for a Halloween party, Oculizer is an advanced DMX lighting automation system that creates real-time, music-reactive light shows by combining Spotify metadata with live audio analysis. It uses mel-scaled FFT to analyze audio and maps frequency components to DMX values through configurable scenes.

⚠️ Note: This project is currently in development and requires some technical setup to get working. Use at your own risk!

Features

Real-time audio reactivity using mel-scaled FFT analysis
Spotify integration for metadata and playback control
Configurable scene system with JSON-based mapping rules
Support for various DMX fixtures:
- RGB lights
- Dimmers
- Strobes
- Lasers
Live scene switching through keyboard commands
MIDI control support
Audio visualization tools for debugging

Prerequisites

Python 3.8+
USB to DMX adapter (compatible with OpenDMX)
DMX-controlled lights
BlackHole virtual audio driver (for macOS) or equivalent
Spotify Premium account

Required Hardware Configuration

DMX lights connected and addressed properly
USB to DMX adapter connected and recognized
Audio routing to capture Spotify playback (e.g., BlackHole setup on macOS)
MIDI controller (optional)

Installation

# Clone the repository
git clone https://github.com/yourusername/oculizer.git
cd oculizer

# Install required packages
pip install -r requirements.txt

Configuration Steps

Spotify Setup:
- Create a Spotify Developer account
- Create a new application
- Set up proper redirect URIs
- Create spotify_credentials.txt with the following format:
```
client_id YOUR_CLIENT_ID
client_secret YOUR_CLIENT_SECRET
redirect_uri YOUR_REDIRECT_URI
```
DMX Profile Configuration:
- Review profiles/ directory for example profiles
- Create/modify profiles to match your DMX setup
- Update channel numbers and fixture types
Scene Configuration:
- Review scenes/ directory for example scenes
- Create/modify scenes to match your desired effects
- Test scenes individually before running full show

Usage

Main script:

python oculize.py

Alternative interfaces:

# MIDI control interface
python run_midi.py

# Basic testing interface
python run_tester.py

# Development/debugging interface
python run_dev.py

Key Commands

q: Quit
r: Reload scenes
Scene-specific hotkeys (defined in scene JSON files)
Space: Manual trigger (when in appropriate mode)

Scene Configuration

Scenes are defined in JSON files with the following structure:

{
    "name": "scene_name",
    "description": "Scene description",
    "type": "effect",
    "midi": 60, # MIDI note number (optional)
    "key_command": "1", # Keyboard command (optional)
    "lights": [
        {
            "name": "light_name",
            "type": "rgb",
            "modulator": "mfft",
            "mfft_range": [0, 20],
            "power_range": [0, 2],
            "brightness_range": [0, 255],
            "color": "red", 
            "strobe": 0
        }
    ]
}

Development Status

This project is actively being developed. Known areas needing attention:

Error handling improvements
Better documentation of scene configuration options
More robust Spotify token refresh handling
General code cleanup and optimization
Additional visualization tools
Better handling of audio routing setup
More flexible light modulators in mapping.py
More audio features
