Spherical harmonics analysis is used to establish theory and design of a higher order recording system, which comprises an array of small microphones arranged in a spherical configuration and associated signal processing. This result has implications to the advancement of future sound field reconstruction systems. An example of a third order system for operation over a 10:1 frequency range of 340 Hz to 3.4 kHz is given.4en200210.1109/ICASSP.2002.57450110036296233
