In an information recording medium, the position of each bit in the bit arrangement (800b) consisting of a plurality of bits is related to each channel corresponding to the position of each loudspeaker in the loudspeaker arrangement (800a) consisting of a plurality of loudspeakers. By the value of each bit, the channel allocation information (800I) is recorded to indicate whether audio data of a corresponding channel is present. Moreover, a plurality of audio data whose presence is indicated by the channel allocation information is recorded for each channel.
