PURPOSE: An acoustic system, an acoustic transmitter, an acoustic transmitting method, and a computer-readable recording medium are provided to generate acoustic data compatible with a 2D image and a 3D image while minimizing the bandwidth. CONSTITUTION: A parameter extractor(111) extracts 3D acoustic parameters(SP3) from the received 3D image data(PI3). An encoder(112) generates a 2D acoustic data stream(SIS2) by encoding 2D acoustic data(SI2) corresponding to 2D image data. A packetizing device(114) generates a compatible stream(CS) by combining the 2D acoustic data stream with the 3D acoustic parameters. A 2D acoustic regenerator(150) regenerates a 2D sound based on the 2D acoustic data extracted from the compatible stream. A 3D acoustic regenerator(160) regenerates a 3D sound based on the 3D acoustic data and the 3D acoustic parameters included in the compatible stream.
