+## Definition
+
+**TCC (Temporal Coarse Caption):**  
+A brief text description for the overall audio scene.  
+*Example*: `a dog barks`
+
+**TDC (Temporal Detailed Caption):**  
+A **caption with timestamp information** for each event.  
+It allows precise temporal control over when events happen in the generated audio.  
+*Example*: `a dog barks(1.0-2.0, 3.0-4.0); a man speaks(5.0-6.0)`
+
+---
+
+## Input Requirements & Format
+
+- **TCC** is **required** for audio generation.
+- **TDC** is **optional**. If provided, it should follow the format:  event1(start1-end1, start2-end2); event2(start1-end1, ...)
+        *Example*:  a dog barks(1.0-2.0, 3.0-4.0); a man speaks(5.0-6.0)
+- **Length** (in seconds) is optional, but recommended for temporal control.
+- **Enable Time Control**: Tick to use TDC and length for precise event timing.
+
+---
+
+## Notes
+
+- If TDC format is incorrect or length is missing, the model will generate audio **without precise temporal control**. 
+- For general audio generation, it is recommended to input '"random"' for TDC.
+- You may leave TDC blank to let the LLM generate timestamps automatically (subject to API quota).
