... High-definition sound processor BA3884F / BA3884S The BA3884F and BA3884S 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. ...

... Therefore, when replaying audio on audio playback systems extremely important that Operating principle To solve the problems described above, the BA3884F / S performs the audio signal processing described below. Phase shift compensation The input signal is separated into three regions : bass (20Hz to 150Hz), middle (150Hz to 2 ...

... This varies the balance of the harmonic component, and is an important factor in determining the tone quality. 432 BA3884F / BA3884S Mode switch The DC voltage on the CTL pin can be used to switch the IC between processing mode and bypass mode. When processing mode is selected, the audio signal is en- hanced using the compensation circuits described above before being output ...
