Abstract
Musical sound signals in at least one frequency band in a low band range are enhanced by a low-pitched sound enhancement processing device. Musical sound signals greater than a predetermined level are compressed by a compression device, such that the level in a low band range would not become excessively large, while musical sound signals with a lower level are enhanced by an enhancement device to be outputted with sufficient sound pressure. Also, the input/output level ratio is determined based on the level of inputted musical sound signals, to prevent the output level from becoming smaller than the input level.
