Claim Text:
1. An audio data processing device comprising: a first input unit that receives input of first audio data representative of a first sound; a second input unit that receives input of second audio data representative of a second sound; a mixing unit that mixes the first audio data and the second audio data to generate mixed audio data; a first output unit that outputs, to a first speaker, audio data being the first audio data and not having undergone the mixing by the mixing unit; a second output unit that outputs, to a second speaker, the mixed audio data generated by the mixing unit; a processor that is provided between a point of branching to the mixing unit and the first output unit on a transmission path between the first input unit and the first output unit, or between the mixing unit and the second output unit, and performs processing of adding an acoustic effect to the audio data; and a delay unit that is provided between the branching point and the first output unit on the transmission path between the first input unit and the first output unit, or between the mixing unit and the second output unit, and delays the audio data so that a relationship of timing between input, to the first speaker, of the audio data output from the first output unit and input, to the second speaker, of the audio data output from the second output unit coincides with a relationship of timing of input between the first audio data at the first input unit and the second audio data at the second input unit, wherein a transmission speed of an audio data transmission path from the second output unit to the second speaker is lower than a transmission speed of an audio data transmission path from the first output unit to the first speaker, and the processor is provided between the branching point and the first output unit on the transmission path between the first input unit and the first output unit.
