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 2.1.0. To install AudioCraft, you can run the following:

```shell
# 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==2.1.0'
# You might need the following before trying to install the packages
python -m pip install setuptools wheel
# 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).
python -m pip install -e '.[wm]'  # if you want to train a watermarking model
```

We also recommend having `ffmpeg` installed, either through your system or Anaconda:
```bash
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](./docs/MUSICGEN.md): A state-of-the-art controllable text-to-music model.
* [AudioGen](./docs/AUDIOGEN.md): A state-of-the-art text-to-sound model.
* [EnCodec](./docs/ENCODEC.md): A state-of-the-art high fidelity neural audio codec.
* [Multi Band Diffusion](./docs/MBD.md): An EnCodec compatible decoder using diffusion.
* [MAGNeT](./docs/MAGNET.md): A state-of-the-art non-autoregressive model for text-to-music and text-to-sound.
* [AudioSeal](./docs/WATERMARKING.md): A state-of-the-art audio watermarking.
* [MusicGen Style](./docs/MUSICGEN_STYLE.md): A state-of-the-art text-and-style-to-music model.

## 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](./docs/TRAINING.md).

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](https://facebookresearch.github.io/audiocraft/api_docs/audiocraft/index.html) for AudioCraft.


## FAQ

#### Is the training code available?

Yes! We provide the training code for [EnCodec](./docs/ENCODEC.md), [MusicGen](./docs/MUSICGEN.md) and [Multi Band Diffusion](./docs/MBD.md).

#### Where are the models stored?

Hugging Face stored the model in a specific location, which can be overridden 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](https://huggingface.co/docs/transformers/installation#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](https://pytorch.org/docs/stable/hub.html#where-are-my-downloaded-models-saved).
