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 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.

摘要： A sound pickup apparatus and method form a bidirectionality and a unidirectionality based on sound signals picked up by microphones arranged at vertices of a triangle. A target sound is extracted by performing a spectral subtraction operation and, with respect to each frequency, a ratio of amplitude spectra of beamformer outputs between outputs is calculated for each microphone array of a directionality forming unit. A mode or median of the calculated ratio of amplitude spectra is set as a correction coefficient which corrects power of beamformer outputs for each of the microphone arrays and a target area sound is extracted.
