1. A live data distribution method of distributing live sound data among a plurality of venues, including a first venue and a second venue, the method comprising:
obtaining distribution data including:
first sound source information according to sound of a first sound source generated at a first location of the first venue and position information of the first sound source;
second sound source information according to a second sound source including ambient sound generated at a second location of the first venue; and
information on space reverberation of the first venue, including:
first reverberation information that varies according to a position of the first sound source; and
second reverberation information that varies according to a position of the second sound source;
distributing the distribution data to the second venue; and
rendering the distribution data and providing at the second venue:
first sound of the first sound source having been performed with localization processing based on the position information of the first sound source;
second sound of the second sound source; and
sound according to the space reverberation, including:
first early reflected sound corresponding to the first sound of the first sound source based on the first reverberation information that varies according to the position of the first sound source;
second early reflected sound corresponding to the second sound of the second sound source based on the second reverberation information that varies according to a position of the second sound source; and
late reverberant sound that is constant independent of the position of the first sound source and the position of the second sound source.
