摘要： An integrated circuit for use as a building block in different embodiments of systems for enhancing audio performance by providing group delay to various frequency components of the signal. The integrated circuit includes four op amps and associated circuitry. Using external connections, the device can be configured as a two-channel stereo device, or can be cascaded for monaural applications. Two of the chips may be cascaded together for stereo applications. External capacitances and resistances are used to control the degree of group delay provided to the signal to realize desired audio enhancement.
