Virtual simulation of spatial audio characteristics
First Claim
1. A system for simulating acoustic performance of speakers, comprising:
- at least one reference speaker;
a user interface;
storage medium storing electronic data representing spatial audio characteristics of at least one demonstration speaker including a directivity pattern reflecting acoustic responses of the at least one demonstration speaker measured at multiple points in space; and
a computer processor or digital signal processor (DSP) configured to;
receive, via said user interface, a first user selection of a first demonstration speaker;
retrieve, from said storage medium, electronic data representing spatial audio characteristics of said first demonstration speaker;
simulate acoustic performance of said first demonstration speaker by applying said spatial audio characteristics of said first demonstration speaker to an acoustic sample to generate a first simulated acoustic output; and
output said first simulated acoustic output via said at least one reference speaker.

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.
