AK7734XQ規(guī)格書(shū)詳情
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.
