高分求如何将用waveIn实现录音,保存到.wav文件中的方法.``````````````
我现在用waveIn实现了录音并用waveOut实现回放,但不知道怎么能把音频流存如文件.我也查了相关资料但好象都没用waveIn\waveOut实现文件保存,请各位大虾给点提示,资料,原码都可以`````谢谢 问题点数：100、回复次数：26Top

自己保存为wav文件格式。Top

简单啊， 构造一个wav头，然后把数据接上一存就ok了Top

是正常了可是它的实现也不是用了waveIn呀,还用了windows下其他东西:(我现在只想用waveIn并且已经实现了各个功能.主要是要在wince下运行,郁闷得很,谁能帮忙看看.放原码了,高手不要见笑,很多是找资料照着写的:)

嗯,这个只是实现了录音播放,能否在此基础上实现录音文件wav的保存呢?我觉得既然我已经能保存到内存中,那保存到wav文件中,只是不知道该怎么组织wav文件.不知道这个想法对不?请高手指点一二.Top

WAV 文件有标准的文件格式，你需要在网上找到它的格式定义，然后根据这个定义，用 WriteFile 写入到文件里。Top
