AMBE-1000是一款高性能多速率语音编解码芯片，采用MBE技术的语音压缩算法，具有语音音质好和编码速率低等优点，语音编解码速率可以在2.4Kbps～9.6Kbps之间以50bps的间隔变化。该程序是使用STC单片机与AMBE-1000串口通讯，实现单板回还功能。-AMBE-1000 is a high performance multi-rate speech codec chip, using MBE technology of voice compression algorithm, with good sound quality and voice and low rate encoding, voice codec rate may be between 2.4Kbps ~ 9.6Kbps to 50bps of the interval change. The program is using the AMBE-1000 STC microcontroller serial communication, but also to achieve the board back function.
