1、MTK 铃声修改1.1 铃声简介MTK 支持的铃声还是比较多的，常见的 MP3，WAV， MID 等等都支持。同时 MTK 既支持数组存储的铃声，也支持资源类型的铃声。不过习惯上我们一般都使用数组类型的铃声。所谓数组类型的铃声，就是把铃声数据按字节顺序存储在数组中，标明铃声的类型和长度，供播放函数使用。1.2 铃声的格式(Audio_Converter.cpp)#define FORMAT_IMY “18“ /* sync with med_main.h */#define FORMAT_MID “17“ /* sync with med_main.h */#define FORMAT_WAV
