|
Audiocraft is a PyTorch library for deep learning research on audio generation. At the moment, it contains the code for MusicGen, a state-of-the-art controllable text-to-music model. |
|
|
|
## MusicGen |
|
|
|
Audiocraft provides the code and models for MusicGen, [a simple and controllable model for music generation][arxiv]. MusicGen is a single stage auto-regressive |
|
Transformer model trained over a 32kHz <a href="https://github.com/facebookresearch/encodec">EnCodec tokenizer</a> with 4 codebooks sampled at 50 Hz. Unlike existing methods like [MusicLM](https://arxiv.org/abs/2301.11325), MusicGen doesn't require a self-supervised semantic representation, and it generates |
|
all 4 codebooks in one pass. By introducing a small delay between the codebooks, we show we can predict |
|
them in parallel, thus having only 50 auto-regressive steps per second of audio. |
|
Check out our [sample page][musicgen_samples] or test the available demo! |

|
|
We use 20K hours of licensed music to train MusicGen. Specifically, we rely on an internal dataset of 10K high-quality music tracks, and on the ShutterStock and Pond5 music data. |
|
|
|
## Installation |
|
Audiocraft requires Python 3.9, PyTorch 2.0.0, and a GPU with at least 16 GB of memory (for the medium-sized model). 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. |
|
pip install 'torch>=2.0' |
|
# Then proceed to one of the following |
|
pip install -U audiocraft # stable release |
|
pip install -U git+https://git@github.com/facebookresearch/audiocraft#egg=audiocraft # bleeding edge |
|
pip install -e . # or if you cloned the repo locally |
|
``` |
|
|
|
## Usage |
|
We offer a number of way to interact with MusicGen: |
|
1. You can play with MusicGen by running the jupyter notebook at [`demo.ipynb`](./demo.ipynb) locally, or use the provided [colab notebook](https://colab.research.google.com/drive/1fxGqfg96RBUvGxZ1XXN07s3DthrKUl4-?usp=sharing). |
|
2. You can use the gradio demo locally by running `python app.py`. |
|
3. A demo is also available on the [`facebook/MusicGen` HuggingFace Space](https://huggingface.co/spaces/facebook/MusicGen) (huge thanks to all the HF team for their support). |
|
4. Finally, you can run the [Gradio demo with a Colab GPU](https://colab.research.google.com/drive/1-Xe9NCdIs2sCUbiSmwHXozK6AAhMm7_i?usp=sharing), |
|
as adapted from [@camenduru Colab](https://github.com/camenduru/MusicGen-colab). |

## API |
|
|
|
We provide a simple API and 4 pre-trained models. The pre trained models are: |
|
- `small`: 300M model, text to music only - [🤗 Hub](https://huggingface.co/facebook/musicgen-small) |
|
- `medium`: 1.5B model, text to music only - [🤗 Hub](https://huggingface.co/facebook/musicgen-medium) |
|
- `melody`: 1.5B model, text to music and text+melody to music - [🤗 Hub](https://huggingface.co/facebook/musicgen-melody) |
|
- `large`: 3.3B model, text to music only - [🤗 Hub](https://huggingface.co/facebook/musicgen-large) |
|
|
|
We observe the best trade-off between quality and compute with the `medium` or `melody` model. |
|
In order to use MusicGen locally **you must have a GPU**. We recommend 16GB of memory, but smaller |
|
GPUs will be able to generate short sequences, or longer sequences with the `small` model. |
|
|
|
**Note**: Please make sure to have [ffmpeg](https://ffmpeg.org/download.html) installed when using newer version of `torchaudio`. |
|
You can install it with: |
|
``` |
|
apt-get install ffmpeg |
|
``` |
|
|
|
See after a quick example for using the API. |
|
|
|
```python |
|
import torchaudio |
|
from audiocraft.models import MusicGen |
|
from audiocraft.data.audio import audio_write |
|
|
|
model = MusicGen.get_pretrained('melody') |
|
model.set_generation_params(duration=8) # generate 8 seconds. |
|
wav = model.generate_unconditional(4) # generates 4 unconditional audio samples |
|
descriptions = ['happy rock', 'energetic EDM', 'sad jazz'] |
|
wav = model.generate(descriptions) # generates 3 samples. |
|
|
|
melody, sr = torchaudio.load('./assets/bach.mp3') |
|
# generates using the melody from the given audio and the provided descriptions. |
|
wav = model.generate_with_chroma(descriptions, melody[None].expand(3, -1, -1), sr) |
|
|
|
for idx, one_wav in enumerate(wav): |
|
# Will save under {idx}.wav, with loudness normalization at -14 db LUFS. |
|
audio_write(f'{idx}', one_wav.cpu(), model.sample_rate, strategy="loudness", loudness_compressor=True) |
|
``` |
|

## FAQ |
|
|
|
#### Will the training code be released? |
|
|
|
Yes. We will soon release the training code for MusicGen and EnCodec. |
