Abstract: The present disclosure generally provides an apparatus and method of controlling an audible signal generated by an audio device to improve the sound quality of the generated audible signal and/or sound quality perceived by a user. In some embodiments, the audio device is able to improve the sound quality generated by the audio device that is generating audible sound based on any type of audio signal. The processes described herein allow the audible signal processor to determine the acoustic fingerprint of the environment in which the audio device is positioned, and thus by use of the method steps disclosed herein to optimize the sound quality in one or more frequency bands of a generated audible signal in real time based on the determined acoustic fingerprint.
