MusicGen - Local AI Music Generator

Generate music from text prompts using Meta's open-source MusicGen model.

Quick Start

# 1. Run the setup script (creates venv, installs dependencies)
cd python_pkg/music_gen
./setup.sh

# 2. Activate the virtual environment
source venv/bin/activate

# 3. Generate music!
python music_generator.py "upbeat electronic dance music with synths"

Usage

Single Generation

# Basic usage
python music_generator.py "jazz piano with soft drums"

# Set duration (in seconds, max ~30 recommended)
python music_generator.py --duration 20 "epic orchestral soundtrack"

# Use smaller/faster model
python music_generator.py --model small "rock guitar riff"

# Use larger/better quality model (needs 16GB+ VRAM)
python music_generator.py --model large "ambient electronic"

Interactive Mode

python music_generator.py --interactive

In interactive mode:

• Type prompts to generate music
• :d 15 - Set duration to 15 seconds
• :h - Show example prompts
• :q - Quit

Model Sizes

Model	Size	VRAM	Quality	Speed
small	~500MB	~4GB	Good	Fast
medium	~3.3GB	~8GB	Better	Medium
large	~6.5GB	~16GB	Best	Slow

Requirements

• Python 3.10+
• 8GB+ RAM (16GB recommended)
• GPU recommended (CUDA or Apple Silicon MPS)
• Works on CPU but much slower

Output

Generated audio files are saved to ./output/ as WAV files with timestamps.

Example Prompts

• "upbeat electronic dance music with heavy bass"
• "calm acoustic guitar melody with soft percussion"
• "epic orchestral soundtrack with dramatic strings"
• "lo-fi hip hop beats for studying"
• "80s synthwave with retro vibes"
• "jazz piano trio with upright bass"
• "ambient electronic music for relaxation"
• "rock guitar riff with drums"
• "classical piano sonata in minor key"

Troubleshooting

Out of Memory

• Try --model small for lower VRAM usage
• Reduce duration with --duration 5
• Close other GPU applications

Slow Generation

• Make sure GPU is detected (check output at startup)
• Use --model small for faster generation
• Reduce duration

No Sound / Corrupted File

• Check if scipy is installed: pip install scipy
• Try a different audio player (VLC recommended)
