Parametric spatial processing is a promising and emerging technique that is fundamentally different from traditional spatial processing techniques. First, a relatively simple sound field model is adopted and the parameters of the model (such as for example the direction of arrival and diffuseness), are estimated in a time-frequency domain. Second, the estimated parameters are used to process the received microphone signals. The compact and efficient representation of the sound field can be used to develop algorithms for different applications. In this tutorial different sound field models and corresponding parameter estimation techniques will be presented. We will then focus on selected applications such as speech enhancement (directional filtering and dereverberation), acoustical zooming, spatial audio communication, surround sound recording, and reproduction.
