Element dependent filtering offers the possibility to optimize the sound coverage of vertical line arrays: distance dependent frequency response, as well as mid-low frequency beaming and air absorption can be partially compensated. Simulation of array elements contributions to venue acoustics is normally the input data for filters calculation, but some phenomena exist in the real world that are hardly addressed by simulations: for example, the dispersion of transducers responses, as well as the acoustic paths atmospheric conditions, among different array elements. This awareness induced us to develop an algorithm with the aim of being robust against these inaccuracies.
