Compensation system and method for sound reproduction
First Claim
1. A sound compensation system for altering an electrical audio signal for input to a sonic reproduction device having associated behavioral characteristics, said system comprising a model of the sonic reproduction device having a plurality of filters that simulate behavioral characteristics of the sonic reproduction device, wherein:
- each said filter has an associated response that is combinable to define an overall response for the model; and
at least one said filter, which corresponds to an individual component of the sonic reproduction device, is replaceable with another filter in response to replacement of the individual component of the sonic reproduction device with another individual component, wherein the other filter simulates a behavioral characteristic of the other individual component.

Abstract
A sound compensation system alters an electrical audio signal for input to a sonic reproduction device having associated behavioral characteristics. The behavior characteristics of the device are defined by individual or groups of individual components of the sonic reproduction device and include mechanical, acoustic and electromagnetic behaviors. The model includes a plurality of filters that simulate at least one of the behavior characteristics of the sonic reproduction device. The filters are defined by digital signal processes or by analog circuits and are characterized by one or more of an associated frequency, time, phase and transient response. These responses combine to define an overall response for the model. The filters include adjustable parameters which are used to alter filter responses to produce responses that are conjugates to the responses of the unaltered filters and thus the sonic reproduction device. A controller modifies the parameters.
