| ### More details | |
| The model will generate a short music extract based on the description you provided. | |
| The model can generate up to 30 seconds of audio in one pass. | |
| The model was trained with description from a stock music catalog, descriptions that will work best | |
| should include some level of details on the instruments present, along with some intended use case | |
| (e.g. adding "perfect for a commercial" can somehow help). | |
| Using one of the `melody` model (e.g. `musicgen-melody-*`), you can optionally provide a reference audio | |
| from which a broad melody will be extracted. | |
| The model will then try to follow both the description and melody provided. | |
| For best results, the melody should be 30 seconds long (I know, the samples we provide are not...) | |
| It is now possible to extend the generation by feeding back the end of the previous chunk of audio. | |
| This can take a long time, and the model might lose consistency. The model might also | |
| decide at arbitrary positions that the song ends. | |
| **WARNING:** Choosing long durations will take a long time to generate (2min might take ~10min). | |
| An overlap of 12 seconds is kept with the previously generated chunk, and 18 "new" seconds | |
| are generated each time. | |
| We present 10 model variations: | |
| 1. facebook/musicgen-melody -- a music generation model capable of generating music condition | |
| on text and melody inputs. **Note**, you can also use text only. | |
| 2. facebook/musicgen-small -- a 300M transformer decoder conditioned on text only. | |
| 3. facebook/musicgen-medium -- a 1.5B transformer decoder conditioned on text only. | |
| 4. facebook/musicgen-large -- a 3.3B transformer decoder conditioned on text only. | |
| 5. facebook/musicgen-melody-large -- a 3.3B transformer decoder conditioned on and melody. | |
| 6. facebook/musicgen-stereo-*: same as the previous models but fine tuned to output stereo audio. | |
| We also present two way of decoding the audio tokens | |
| 1. Use the default GAN based compression model. It can suffer from artifacts especially | |
| for crashes, snares etc. | |
| 2. Use [MultiBand Diffusion](https://arxiv.org/abs/2308.02560). Should improve the audio quality, | |
| at an extra computational cost. When this is selected, we provide both the GAN based decoded | |
| audio, and the one obtained with MBD. | |
| See [github.com/facebookresearch/audiocraft](https://github.com/facebookresearch/audiocraft/blob/main/docs/MUSICGEN.md) | |
| for more details. | |

| (you will then need a paid GPU from HuggingFace). | |
| If you have a GPU, you can run the gradio demo locally (click the link to our repo below for more info). | |
| Finally, you can get a GPU for free from Google | |
