In this paper, active control is used in order to reproduce a given sound field in an extended spatial region. A method is proposed which minimizes the reproduction error at a number of control positions with the reproduction sources holding a certain relation within their complex strengths. Specifically, it is suggested that the phase differential of the(More)
The generalisation of conventional linear time invariant filter theory from one dimension to the two-dimensional time-frequency (TF) domain provides a powerful tool for the simulation of complex time variable systems. TF filtering is performed as convolution in the TF domain and is based on non-parametric modelling using direct convolution along the time or(More)
