1. Introduction to OpenAI Jukebox

OpenAI Jukebox is a generative model that employs deep learning techniques to create new music. It has been trained on a large dataset of over a million songs, including various genres, artists, and languages. The model can generate music with lyrics in the style of a specific artist, or even create entirely new compositions.

2. Prerequisites for Using Jukebox

Before diving into the world of Jukebox, you need to ensure you have the following prerequisites:

• A working Python environment (Python 3.7 or higher)
• An NVIDIA GPU with CUDA support (for faster training and generation)
• A Google account with access to Google Colab (optional, but recommended for users without a powerful GPU)

3. Setting Up Jukebox

To set up Jukebox, follow these steps:

1. Clone the OpenAI Jukebox repository to your local machine.

   git clone https://github.com/openai/jukebox.git

2. Install the required Python packages.

   cd jukebox
   pip install -r requirements.txt

3. Download the pre-trained Jukebox models.

   python -m jukebox.train --hps=small --name=small --sample_length=1048576 --bs=4 --audio_files_dir=./data/samples --labels=True --train --test --level=0 --aug_shift --aug_blend --save_iters=500

   This command will download the small model, which is suitable for most use cases. You can replace small with 1b_lyrics for the larger model.

4. Generating Music with Jukebox

To generate music with Jukebox, follow these steps:

1. Create a sample.py file with the following code:

   from jukebox.make_models import make_vqvae, make_prior, MODELS, make_model
   from jukebox.hparams import Hyperparams, setup_hparams
   from jukebox.sample import sample_single_window, _sample, sample_partial_window
   import argparse
   
   # Modify the following parameters as needed
   model = "small"  # or "1b_lyrics"
   artist = "The Beatles"
   genre = "Rock"
   prompt = "Imagine a world where everyone is happy and living in harmony."
   length_in_seconds = 20
   temperature = 0.8
   
   # Prepare the model, tokens, and hparams
   hps = Hyperparams()
   hps.sr = 44100
   hps.n_samples = (hps.sr * length_in_seconds) // 16 * 16
   hps.name = model
   hps.sample_length = 1048576
   hps.load_jukebox_model(hps, model, 'cuda')
   zs = [t.zeros(hps.n_samples // (2 ** (i * 2)), dtype=t.long, device='cuda') for i in range(hps.levels)]
   
   # Generate music
   zs = _sample(zs, labels, sampling_kwargs, [None], hps)
   t.save(zs, f"{artist}-{prompt}.pt")
   

2. Run the sample.py script.

   python sample.py

3. Convert the generated .pt file into a .wav file.

   python jukebox/sample.py --mode=reconstruct --name=small --codes_file="{artist}-{prompt}.pt"

4. You can now listen to your generated music in the {artist}-{prompt}.wav file.

5. Exploring Advanced Features

Jukebox offers several advanced features, including:

• Custom lyrics: You can provide your own lyrics for the generated music.
• Sampling temperature: Adjust the sampling temperature to control the randomness of the generated music (lower values result in more conservative samples, while higher values yield more experimental results).
• Multi-level generation: Generate music at different levels of the VQ-VAE hierarchy to control the generation quality and speed.

You can modify the sample.py script to explore these features and customize the generated music to your preferences.

6. Conclusion

OpenAI Jukebox is a powerful tool for music production, allowing users to generate new tunes and explore innovative sounds. By following this guide, you can harness the power of Jukebox for your own music production and create next-level compositions. Happy music-making!
