AUDIO SIGNAL CORRECTION AND CALIBRATION FOR A ROOM ENVIRONMENT

摘要

Disclosed are an apparatus and method of processing an audio signal to optimize audio for a room environment. One example method of operation may include recording the audio signal generated within a particular room environment and processing the audio signal to create an original frequency response based on the audio signal. The method may also include creating at least two iterative filters based on at least two separate frequency ranges of the original frequency response, calculating an error difference between the frequency response modified by the at least two iterative filters and the original frequency response, and applying the error difference to the audio signal.

1. A method, comprising:
processing an audio signal to create an original frequency response; creating at least two iterative filters based on at least two separate frequency ranges of the original frequency response; determining an error difference between the frequency response modified by the at least two iterative filters and the original frequency response; separating peaks and dips of the original frequency response signal based on a means-square-error curve fitting a frequency range of interest of the original frequency response; and applying the error difference to the audio signal.
