频便携式系统的理想选择，下面介绍它在 系统

中的实际应用。-Audio compression algorithm, so that) format widely used) players, and other consumer electronic products has become a popular product. In these portable systems, front-end audio codec play quality (sampling precision, sampling rate), play time (power), etc. play a more crucial role, with high accuracy, low power front-end chip is to improve product performance of highly effective solutions. Digital codec with bit sampling precision, recording playback mode, only the power of portable digital audio system is ideal, here it is the practical application in the system.
