| Abstract | A preliminary study is presented that investigates processing of microphone array signals for multi-channel recording applications. Generalised, perceptually and acoustically based approaches are taken, where a spaced array of M microphones is mapped to an array of L loudspeakers. The principal objective is to establish transformation matrices that integrate both microphone and loudspeaker array geometry in order to reproduce a subjectively accurate illusion of the original soundfield. Techniques of acoustical vector synthesis and plane wave reconstruction are incorporated at low frequencies migrating to an approach based upon head-related transfer functions (HRTFs) at higher frequencies. Error surfaces based on the HRTF reconstruction error are used to assess perceptually relevant solutions. Simulation results presented in a 5-channel format are calculated for processed audio material with and without acoustical boundary reflections.
