Abstract:
1. A sound-image control device comprising: a sound-image controller that processes a left sound signal and a right sound signal to localize a sound image at a predetermined position, wherein the sound-image controller performs control for enhancing a sense of depth to a sound image originally included in an input sound signal, wherein the sound-image controller performs control for enhancing the sense of depth to the sound image originally included in the input sound signal, on a basis of a level of the input sound signal, wherein the sound-image controller includes: wherein the sound-image controller further includes a delay controller that controls a signal delay amount for the delay unit in accordance with the level of the input sound signal, and wherein the delay controller reduces at least the signal delay amount for the delay unit in a level range that is higher than a first level of the input sound signal or increases at least the signal delay amount for the delay unit in a level range that is lower than a second level that is lower than the first level of the input sound signal.
