Abstract
Embodiments of the present invention are directed to a system and method for demonstrating spatial performance of a demonstration speaker model to consumers in order to evaluate different speakers. The system and method comprise a microphone array for recording the output of the demonstration speaker model. The system and method comprise acoustic input samples for processing to an acoustic output and a processor for determining characteristics of each microphone recording, and processing an acoustic input sample and characteristics of each microphone recording corresponding to a selected demonstration speaker model. The system and method further comprise a reference speaker model for outputting an acoustic signal based on the result of the processing. The processing compensates for the performance characteristic of the reference speaker and the performance characteristic of the selected demonstration speaker so as to mimic the spatial characteristics of the demonstration speaker while avoiding bias from the reference speaker.
