Audio processing in consumer devices is incorporating more spatial information. Performance assessment of such devices requires accurate automated simulation of real world acoustic scenarios. This paper reviews the design and validation of a sound field duplication system for this purpose. Theoretical considerations provide guidance on the design and expected performance; an objective measure of the array setup is used to validate construction; and a subjective test approach is proposed to verify accurate duplication is achieved. The key contribution of the work is to introduce and demonstrate the concept of generational loss for comparative performance assessment of sound field duplication. This approach will be used to further investigate robustness and choose from alternative reconstruction approaches towards creating testing standards.
