Abstract
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 identifying a target sub-region of the frequency response which has a predetermined area percentage of a total area under a curve generated by the frequency response, determining whether the target sub-region is a narrow energy region, creating a filter to adjust the frequency response, and applying the filter to the audio signal.
Claims20
A method, comprising:
- creating an original frequency response based on an audio signal generated within an environment;
- identifying a target sub-region of the frequency response that is determined to be a narrow energy region;
- performing an operation on the target sub-region to create a new flattened sub-region;
- creating at least one filter to adjust the frequency response, the at least one filter comprising at least one parameter based on the flattened sub-region;
- and
- applying the at least one filter to the audio signal.
An apparatus, comprising:
- a memory;
- and
- a processor configured to:
- create an original frequency response based on an audio signal generated within an environment;
- identify a target sub-region of the frequency response that is determined to be a narrow energy region;
- perform an operation on the target sub-region to create a new flattened sub-region;
- create at least one filter to adjust the frequency response, the at least one filter comprising at least one parameter based on the flattened sub-region;
- and
- apply the at least one filter to the audio signal.
A non-transitory computer readable storage medium comprising instruction that when read by a processor perform:
- creating an original frequency response based on an audio signal generated within an environment;
- identifying a target sub-region of the frequency response that is determined to be a narrow energy region then performing an operation on the target sub-region to create a new flattened sub-region;
- creating at least one filter to adjust the frequency response, the at least one filter comprising at least one parameter based on the flattened sub-region;
- and
- applying the at least one filter to the audio signal.
