 ## News and Updates
 
+* **2025.09.23 🔥**: We have released the [Data Processing Pipeline](https://github.com/tencent-ailab/SongPrep), which is capable of **analyzing the structure and lyrics** of entire songs and **providing precise timestamps** without the need for additional source separation. On the human-annotated test set [SSLD-200](https://huggingface.co/datasets/waytan22/SSLD-200), the model’s performance outperforms mainstream models including Gemini-2.5, Seed-ASR, and Qwen3-ASR.
 * **2025.07.25 🔥**: SongGeneration can now run with as little as **10GB of GPU memory**.
 * **2025.07.18 🔥**: SongGeneration now supports generation of **pure music**, **pure vocals**, and **dual-track (vocals + accompaniment separately)** outputs.
 * **2025.06.16 🔥**: We have released the **SongGeneration** series.
