AK7736A Description
The AK7736A is a highly integrated audio digital signal processor with integrated 2ch SRC. It includes internal memories for digital audio p rocessing, that allows surround effect process, time alignment and parametric equalizing. More ove r, the AK7736A can process b oth data and filter coefficients as floatin g point data so that high accuracy IIR/FIR filter performance can be achiev ed easily.
