Provided are a sound field forming apparatus and a method that enhances the reproducibility of a wavefront at a listener position. The sound field forming apparatus has a position acquisition unit to acquire position information indicative of a position of a listener or a position of a sound source to be formed, a control point specification unit to specify a control point with a distance from a speaker array of the listener or the sound source on the basis of the position information, and a filter unit to generate a speaker drive signal for forming a predetermined sound field by the speaker array by convoluting a filter coefficient corresponding to the specified control point with a sound source signal.
