CAMAD - Computer Assisted Microphone Array Design

Document Thumbnail

The basic aim of Microphone Array Design is to create microphone array recording systems with smooth seamless or ‘Critically Linked’ segment coverage of the surround sound field. Each configuration must take into account the interaction of the many design parameters, with the specific coverage of each segment that is required. The difficulty in the manipulation of these many parameters is one of the major obstacles in developing a wide range of microphone arrays that meet the needs of each particular sound recording environment. This paper will outline the various parameters that need to be taken into consideration and explain the basic approach to developing MATLAB based software that gives a clear and unambiguous display of all the salient characteristics needed to achieve a stable and reliable microphone array, no matter the number of channels involved, or the type of directivity pattern chosen for each microphone.
