Sound reproduction method and apparatus distinguishing multiple sound sources

摘要

PURPOSE: A method and an apparatus for outputting sounds by compartmentalizing multiple sound sources are provided to output sound with spatial perception using sound sources which do not include spatial information. CONSTITUTION: A first location corresponding to a first sound source and a second location corresponding to a second sound source are set up(S101). The first location corresponding to the first sound source and the second location corresponding to the second sound source are defined in a virtual space. A first space transmitting function pitching with the first location and a second space transmitting function determined by the second location are set up(S102). The first space transmitting function models the sound wave transmitting response from the first location to the virtual listening location. The second space transmitting function models the sound wave transmitting response from the second location to the virtual listening location. The result applying the first space transmitting function on the first sound source is outputted as a first sound(S103). The result applying the second space transmitting function on the second sound source is outputted as a second sound.
