| Popis: | Like the concept of free-viewpoint TV (FTV), the audio data should be rendered according to video data. However, on condition that minimum numbers of microphone are used, it is difficult to acquire accurate audio signal for rendering audio data to the image with the choice of view point. Especially, degradation of high frequency components (HFC) happens due to the characteristic of polar pattern for microphone. The degradation of HFC causes imperfection of signal restoration and leads to the degradation of clarity for hearing. In this paper, a compensation method for the degradation of HFC audio signal is proposed for producing an immersive audio effect at realistic media. Our experimental results show that low frequency components (LFC) of audio signal had a little directional degradation in spite of effect of the polar patterns of microphone and the compensation of HFC can be realized with adapting the attenuation inclination of LFC. This research is expected to be helpful for producing an immersive audio effect for a realistic media. |
