## Installation ```bash pip install torch torchaudio "transformers<5" einops ``` > Tested with Python 3.10, torch 2.8.0+cu128, transformers 4.57. Not compatible with transformers 5.x. ## Prompt Format Dasheng-AudioGen uses structured tags to describe different audio aspects. A valid prompt **must start with the `<|caption|>` tag**, which provides the overall scene description. Other tags are optional and can be included as needed. | Tag | Description | Required | |-----|-------------|:--------:| | `<\|caption\|>` | Overall audio scene description | Yes | | `<\|speech\|>` | Speaker identity and speaking style | No | | `<\|asr\|>` | Spoken transcript / dialogue | No | | `<\|sfx\|>` | Sound effects | No | | `<\|music\|>` | Background music | No | | `<\|env\|>` | Environmental ambience | No | **Rules:** - The prompt must begin with `<|caption|>` — prompts without it will be rejected. - Only include tags that are relevant; omit tags with no content (e.g., skip `<|music|>` if there is no music). > **Multilingual note:** When using the multilingual model, all descriptive tags (`caption`, `speech`, `sfx`, `music`, `env`) should be in **English**. Only the `<|asr|>` field (the actual speech content to synthesize) uses the target language. ## Quick Start ### Usage 1: Aspect-wise Composition Pass each aspect as a named argument. The `caption` field is required; all other fields are optional. ```python import torchaudio from transformers import AutoModel model = AutoModel.from_pretrained("mispeech/Dasheng-AudioGen", trust_remote_code=True).cuda() prompt = model.compose_prompt( caption="A gritty detective narrating over the sound of heavy rain and a melancholic solo jazz saxophone.", speech="gritty deep male voice", music="melancholic solo saxophone", env="distant urban ambience", sfx="heavy rain hitting pavement", asr="The city never sleeps, but it sure knows how to cry.", ) audio = model.generate(prompt) torchaudio.save("output.wav", audio.cpu(), 16000) ``` ### Usage 2: Pre-formatted Prompt String Pass a complete tagged string via the `prompt` parameter. The string must start with `<|caption|>`. ```python import torchaudio from transformers import AutoModel model = AutoModel.from_pretrained("mispeech/Dasheng-AudioGen", trust_remote_code=True).cuda() prompt = model.compose_prompt( prompt="<|caption|> A gritty detective narrating over the sound of heavy rain and a melancholic solo jazz saxophone. <|speech|> gritty deep male voice <|asr|> The city never sleeps, but it sure knows how to cry. <|sfx|> heavy rain hitting pavement <|music|> melancholic solo saxophone <|env|> distant urban ambience" ) audio = model.generate(prompt) torchaudio.save("output.wav", audio.cpu(), 16000) ``` ### Batch Inference ```python import torchaudio from transformers import AutoModel model = AutoModel.from_pretrained("mispeech/Dasheng-AudioGen", trust_remote_code=True).cuda() prompts = [ model.compose_prompt(caption="A cat meowing softly.", sfx="Soft cat meow."), model.compose_prompt(caption="Thunder rolling in the distance.", env="Stormy night ambience."), model.compose_prompt(caption="A piano playing a gentle melody.", music="Soft piano ballad."), ] audios = model.generate(prompts) for i, audio in enumerate(audios): torchaudio.save(f"output_{i}.wav", audio.unsqueeze(0).cpu(), 16000) ``` ### Generation Parameters ```python import torchaudio from transformers import AutoModel model = AutoModel.from_pretrained("mispeech/Dasheng-AudioGen", trust_remote_code=True).cuda() prompt = model.compose_prompt(caption="A dog barking in a park") audio = model.generate( prompts=prompt, num_steps=25, # number of denoising steps (default: 25) guidance_scale=5.0, # classifier-free guidance scale (default: 5.0) sway_sampling_coef=-1.0, # sway sampling coefficient (default: -1.0, 0 for linear) ) torchaudio.save("output.wav", audio.cpu(), 16000) ``` ## Acknowledgments Dasheng-AudioGen was developed with contributions from **XIAOMI LLM PLUS** and **SJTU X-LANCE**. ## Citation ```bibtex @article{mei2026dashengaudiogen, title = {Dasheng AudioGen: A Unified Model for Generating Coherent Audio Scenes from Text}, author = {Jiahao Mei and Heinrich Dinkel and Yadong Niu and Xingwei Sun and Gang Li and Yifan Liao and Jiahao Zhou and Junbo Zhang and Jian Luan and Mengyue Wu}, journal = {arXiv preprint arXiv:2605.27838}, year = {2026} } ``` ## License This project is released under the [Apache License 2.0](LICENSE).
