我已经调用了麦克风成功录音，但保存成本地格式一直出错！有大侠有例子吗？
根据你的文件内容 把这些成员填上放到你的文件头 就是一个wav文件了啊 音频文件打包就是这么干的
WAV 格式就是普通的pcm raw 数据加上一个wav的头信息 unsigned charwav_header[] = {
'R', 'I', 'F', 'F', //"RIFF"标志
0xfc, 0xff, 0xff, 0xff, //文件长度
'W', 'A', 'V', 'E', //"WAVE"标志
'f', 'm', 't', ' ', //"fmt"标志
16, 0, 0, 0, //过渡字节（不定）
WAVE_FORMAT_PCM, WAVE_FORMAT_PCM >>8,// 格式类别
0, 0, //声道数
0, 0, 0, 0, //采样率
0, 0, 0, 0, //位速
0, 0, //一个采样多声道数据块大小
16, 0, //一个采样占的bit数
'd', 'a', 't', 'a', //数据标记符＂data＂
0xd8,0xff, 0xff, 0xff //语音数据的长度，比文件长度小36
}加上就好

用.net自带录音
利用插件
