Currently, audio retrieval algorithms, which are based on Central Processing Unit ( CPU ) architecture, have been relatively mature. Simply modify the algorithm has been unable to obtain significant performance improvement. 目前,基于中央处理单元(CentralProcessingUnit,CPU)架构的音频检索算法已经相对成熟,仅仅通过改进算法无法在短时间内获得显著的性能提升。
The components included in the hardware system are audio sampling and MP3 encoding module, bluetooth transmission module, processing unit and power module. 硬件设计包括:立体声音源输入采样及MP3编码模块、立体声蓝牙发送模块、处理器主板模块、系统电源模块。
