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.
FApplications
Component stereo systems, radio cassette players, car
stereo systems, televisions, VCRs, multimedia PCs,
computer game machines and karaoke machines.
FFeatures
1) Corrects distortion in the rising section of audio sig-
2) To allow application with all types of speakers and
