This library contains components that can be used to efficiently generate noise which can be used in simulations. Examples of the these components are:

- Sample-free TimeBasedNoise which allows for faster system simulations
- Signal-based noise which allows a noise that is based on a system input. This signal-based noise can be for example as a source of road-irragularities.
- Colored noise

The AdvancedNoise library is developed at the DLR Institute of System Dynamics and Control.

The autors of the library are: A. Klöckner, F. v.d. Linden, D. Zimmer, M. Otter.

**Acknowledgments**

Many thanks goes to T. Beutlich for his help in cleaing up the library, M. Sjoelund for his help with OpenModelica tests and D. Winkler for his advice with the Noise C code.
