Nucleus系统的移动终端录音功能设计

摘要

针对Nucleus系统的移动设备硬件平台,分析了自适应多速率(AMR)编解码算法的工作原理,提出了基于AMR语音压缩算法的语音录音功能的设计方案,重点研究了手机语音多媒体软件设计.通过交叉编译环境,对软件进行了调试,运行良好.%In view of the hardware platform of mobile devices based on Nucleus system,working principle of adaptive multi-rate (AMR) voice coding/decoding is analyzed.A recording fuction design scheme based on AMR voice compressing algorithm is proposed,and the detail of the mobile phone multi-media software is given. The software is debugged in the cross-compiler environment,and runs smoothly.
