The aim of sound field reproduction is to physically reproduce a sound field in an extended area using loudspeaker arrays. Typically, the virtual scene is described by a composition of simple sources (spherical waves, plane waves) fed by monophonic signals from proximity microphones or a microphone array recording. It would be useful to combine these approaches in order to separate monophonic signals to drive simple foreground virtual sources from the remaining immersing sound environment. In this paper, the combination of proximity microphones and microphone arrays is investigated in order to separate the sound source signals with proximity microphones from the remaining sound environment. Optimal (Wiener) filters are used for this purpose. Results of numerical simulations and acoustic imaging illustrate the viability of the approach.
