... High-definition sound processor BA3880AS / BA3880AFS The BA3880AS and BA3880AFS are sound processor ICs that perform phase and harmonic compensation on audio signals to accurately reproduce the "rise" section of audio signals that determines the characteristics of the sound, and thus reproduce the original recording as naturally as possible. ...

... Audio ICs ! ! ! ! Circuit operation The BA3880AS and BA3880AFS high-definition sound processor system ICs treat the amplifiers and speakers as a total audio systems, and perform signal processing at the amplifier input stage to accurately reproduce the rise sections of audio signals that determine the characteristics of sound, and ensure that the replayed audio is as close to the original sound and as natural sounding as possible ...
