Abstract:
A sound quality regulation apparatus for regulating split frequency bands of an input signal, comprising:an attenuation unit which is capable of receiving an input signal and a regulation signal associated with at least one predetermined frequency band, and is adapted to generate an attenuated signal of said input signal which is attenuated in said frequency band based on said regulation signal; an amplification unit which is capable of receiving said attenuated signal from said attenuation unit and a regulation signal associated with at least one frequency band, and is adapted to generate an output signal which is amplified in said frequency band based on said regulating signal; and at least one sound regulator associated with one frequency band of said input signal, said sound regulator including a SC filter receiving said attenuated signal from said attenuation unit and permitting the frequency band associated with said sound regulator to pass therethrough as a regulation signal, and a selection device connected with said SC filter and adapted to selectively feeding said regulation signal to either said attenuation unit, said amplification unit, or none of said units.
