[AK7734] AK7734 Audio DSP with 2-Channel ADC/SRC GENERAL DESCRIPTION The AK7734 is a highly integrated audio digital signal processor with integrated 2ch 24bit ADC and 2ch SRC. It includes internal memories for digital audio processing, that allows surround effect process, time alignment and parametric equalizing. More over, the AK7734 can process both data and filter coefficients as floating point data so that high accuracy IIR/FIR filter performance can be achieved easily. The internal SRC has various sampling rate converting modes, corresponds many sampling rates without changing the DSP operating sampling frequency. The AK7734 can operate a hands-free software by AKM, as well as sound processing, by programs downloaded via the microprocessor interface.
