Abstract: A sound reproduction system includes a sound processing device connected to a stationary first output device including a plurality of sound output units and a portable second output device including a plurality of sound output units. In the sound reproduction system, the sound processing device generates a first sound output signal to be output to the first output device and a second sound output signal, which is different from the first sound output signal, to be output to the second output device. At least the second sound output signal out of the first and second sound output signals includes a signal that is obtained by performing 3-D sound processing.
