The use of spatial audio reproduction techniques is widely employed for the subjective analysis of concert halls and, more recently, complex outdoor sound environments. In this work a binaural reproduction technique is developed based on a 32-channel spherical microphone array, optimized for the simulation of a virtual microphone with directional characteristics that approximate the directivity of the human head. A set of weights is calculated for each microphone of the constituting array based on a regularized least-square solution. This technique allows for adaptation of the auditory scene based on source direction. The performance of variants of the technique has been evaluated by means of listening tests. Furthermore, its use for the auralization of outdoor soundscapes has been illustrated.
