+DiffRhythm 2 (Chinese: 谛韵, Dì Yùn) is the next-generation open-sourced music generation framework that advances the original DiffRhythm with a semi-autoregressive diffusion architecture. It is capable of generating full-length songs with precise lyric alignment and coherent musical structures. The name inherits the essence of DiffRhythm — “Diff” reflects its diffusion-based generative backbone, while “Rhythm” emphasizes its dedication to musicality and temporal flow. The Chinese name 谛韵 (Dì Yùn) continues this dual symbolism: “谛” (attentive listening) represents perceptual awareness, and “韵” (melodic charm) captures the expressive beauty of music.

+
+
+## 📢 News and Updates
+
+* **2025.10.30** 🚀 We released the [DiffRhythm2 paper](https://arxiv.org/pdf/2510.22950), demo code, and [model weights](https://huggingface.co/ASLP-lab/DiffRhythm2).
+
+## 📋 TODOs
+- [ ] Support Colab.
+- [ ] Gradio support.
+- [ ] Song extension.
+- [ ] Instrumental music generation.
+- [x] Release code and weights.
+- [x] Release paper to Arxiv.
+
+## 🔨 Inference
+
+Following the steps below to clone the repository and install the environment.
+
+```bash 
+# clone and enter the repositry
+git clone https://github.com/ASLP-lab/DiffRhythm2.git
+cd DiffRhythm2
+
+# install the environment
+## espeak-ng
+# For Debian-like distribution (e.g. Ubuntu, Mint, etc.)
+sudo apt-get install espeak-ng
+# For RedHat-like distribution (e.g. CentOS, Fedora, etc.) 
+sudo yum install espeak-ng
+# For MacOS
+brew install espeak-ng
+# For Windows
+# Please visit https://github.com/espeak-ng/espeak-ng/releases to download .msi installer
+
+## install requirements
+pip install -r requirements.txt
+```
+
+On Linux you can now simply use the inference script:
+```bash
+# For inference using a reference WAV file
+bash inference.sh
+```
+
+Weights will be automatically downloaded from Hugging Face upon the first run.
+
+Example files of lyrics and reference audio can be found in `example`. 
+
+
+## 📜 License & Disclaimer

+DiffRhythm 2 (code and weights) is released under the [Apache License 2.0](https://www.apache.org/licenses/LICENSE-2.0). This open-source license allows you to freely use, modify, and distribute the model, as long as you include the appropriate copyright notice and disclaimer.
+
+We do not make any profit from this model. Our goal is to provide a high-quality base model for music generation, fostering innovation in AI music and contributing to the advancement of human creativity. We hope that DiffRhythm 2 will serve as a foundation for further research and development in the field of AI-generated music.
