An audio data processor includes: a digital interface configured to transfer first audio data to an external apparatus through a one-way bus and transfers second audio data being in parallel with the first audio data regarding playback time to the external apparatus through an asynchronous two-way bus; and a controller configured to output a bit stream obtained by adding time information for specifying the playback time successively to the first audio data to the one-way bus, acquire an output request issued for each piece of the time information obtained successively from the bit stream from the external apparatus through the asynchronous two-way bus, and output a part of the second audio data corresponding to the time information of the output request through the asynchronous two-way bus.
