Abstract:
The present invention relates to a method and system for correcting acoustical characteristics of a sound signal in a listening environment caused by changes of spatial characteristics of the listening environment. Therein, a reference room transfer function of the listening environment is provided, and a changed room transfer function is adaptively determined, which is caused by changes of spatial characteristics of the listening environment. Further, equalizing parameters are determined for the sound signal based on the reference room transfer function using the changed room transfer function to compensate for the changed room transfer function.

Claim (Index 16):
A system for correcting audio characteristics of a sound signal in a listening environment, they system comprising:\n a data storage, at least one audio loudspeaker for generating a sound output from a sound signal; at least one sensor for obtaining a total sound signal representative of a total sound level in the listening environment, memory configured to store program code, at least one processor coupled with the memory and configured to execute the program code, wherein execution of the program code causes the at least one processor to perform the following: provide a reference room transfer function of the listening environment from the data storage; adaptively determine a changed room transfer function based on the total sound signal, wherein the changed room transfer function is different from the reference room transfer function and caused by changes of spatial characteristics of the listening environment; determine equalizing parameters for the sound signal based on the reference room transfer function using the changed room transfer function, to compensate for the changed room transfer function; and apply the determined equalizing parameters to the sound signal.
