A sound field control apparatus is provided with a memory storing first and second sound field data; a first digital sound processor convoluting the first sound field data to a sum signal of two channel stereophonic input signals to produce a first initial reflection sound signal group; and a second digital sound processor convoluting the second sound field data to a difference signal of the two channel stereophonic input signals to produce a second initial reflection sound signal group. Thus, sound field reproduction which is richer in flexibility and change can be materialized. Sound fields created by the sound field data supplied to each digital sound processor can independently be changed and thereby it is possible to cause the sound field reproduction to be widely varied as a whole.
