AudioCraft

AudioCraft is a PyTorch library for deep learning research on audio generation. AudioCraft contains inference and training code for two state-of-the-art AI generative models producing high-quality audio: AudioGen and MusicGen.

Installation

AudioCraft requires Python 3.9, PyTorch 2.0.0. To install AudioCraft, you can run the following:

# Best to make sure you have torch installed first, in particular before installing xformers.
# Don't run this if you already have PyTorch installed.
python -m pip install 'torch>=2.0'
# Then proceed to one of the following
python -m pip install -U audiocraft  # stable release
python -m pip install -U git+https://git@github.com/facebookresearch/audiocraft#egg=audiocraft  # bleeding edge
python -m pip install -e .  # or if you cloned the repo locally (mandatory if you want to train).

We also recommend having ffmpeg installed, either through your system or Anaconda:

sudo apt-get install ffmpeg
# Or if you are using Anaconda or Miniconda
conda install "ffmpeg<5" -c conda-forge

Models

At the moment, AudioCraft contains the training code and inference code for:

• MusicGen: A state-of-the-art controllable text-to-music model.
• AudioGen: A state-of-the-art text-to-sound model.
• EnCodec: A state-of-the-art high fidelity neural audio codec.
• Multi Band Diffusion: An EnCodec compatible decoder using diffusion.

Training code

AudioCraft contains PyTorch components for deep learning research in audio and training pipelines for the developed models. For a general introduction of AudioCraft design principles and instructions to develop your own training pipeline, refer to the AudioCraft training documentation.

For reproducing existing work and using the developed training pipelines, refer to the instructions for each specific model that provides pointers to configuration, example grids and model/task-specific information and FAQ.

API documentation

We provide some API documentation for AudioCraft.

FAQ

Is the training code available?

Yes! We provide the training code for EnCodec, MusicGen and Multi Band Diffusion.

Where are the models stored?

Hugging Face stored the model in a specific location, which can be overriden by setting the AUDIOCRAFT_CACHE_DIR environment variable for the AudioCraft models. In order to change the cache location of the other Hugging Face models, please check out the Hugging Face Transformers documentation for the cache setup. Finally, if you use a model that relies on Demucs (e.g. musicgen-melody) and want to change the download location for Demucs, refer to the Torch Hub documentation.
