| Abstract(in English) | 3D sound wave representation theory without sound source localization and is proposed in this paper based on the ray-space representation of light rays which is independent of object's specifications, and sub-band signal processing of sound waves. An array of beam-formed dynamic microphone-arrays (MAs), are set and active microphones with correct interval for the given frequency layer captures a multi frequency layer sound-image (SImage) by scanning the viewing range of a camera in the same location, containing blocks of sound wave with a certain duration, and generates a multi frequency layered sound wave ray-space. The geometry compensation is done using the corresponding images in the location of each MA or SImages or their combination, for each frequency layer. Sound of an SImage is generated by averaging the sound wave in each block. After combining each layer sound in frequency domain and inverse transformation to time domain, the desired sound is generated. |
