A sound field controller including a plurality of output channels for respectively supplying signals to a plurality of speakers, includes: a weighting-coefficient outputting unit which outputs weighting coefficients for determining how the signals on the plurality of channels for reproducing a sound field are to be distributed to the output channels, according to a relative positional relationship between the sound field and a listener; an input unit which inputs positional relation data indicating the relative positional relationship; and a distribution controller which distributes the signals on the plurality of channels to the output channels on the basis of the outputted weighting coefficients according to the inputted positional relation data.
