acoustic signal orientation system的用法和样例：
- In acoustic signal processing,it is valuable to determine whether a real room acoustic system is nonlinear deterministic.
- Nicety and easy operational frame orientation system.
- The underwater acoustic signal is the main information for the underwater detection and identification system, so it is very important to get the acoustic signal efficiently.
- A nondestructive testing hardware system for eggshells based on DSP was established. The system had multiple functions,such as controlling knock device,sampling and processing acoustic signal emitted by eggs,communicating with PC and so on.
