In previous papers the Multichannel Microphone Array Design (MMAD) procedure has been used mainlyto determine the design of arrays giving complete 360° coverage of the sound field. Many soundrecording engineers however use the main microphone array to cover only the front sound stage, and addin early reflections and reverberation either by artificial means (electronic generation) or by using asecond array in the reverberation field. This paper describes MMAD procedure applied to only frontcoverage of the main sound stage using 3,4 or 5 channels-microphones, covering any desired anglewithin the front hemisphere, and for the usual 1st order microphone directivities. Various array alignmentsare described in the form of the arc-of-a-circle with different radius. All arrays described are criticallylinked (seamless) within the front hemisphere.
