音频数据读取 [英] Audio data reading

问题描述

实际上是MMIOINFO.
为什么用于打开wave文件.
MMIOINFO是否可以使用任何其他数据成员代替预定义的数据成员?

PLZ 请有人向我解释.我很困惑.

[没有提示，没有txtspk]

What is actually MMIOINFO.
Why it is used for opening an wave file .
can we use any other datamembers instead of the predefined datamembers for MMIOINFO?

PLZ Please someone explain me. I am confused.

[No shouthing, no txtspk]

推荐答案

该结构定义了很多输入函数. IOInfo是返回打开文件功能的返回.

处理由mmioOpen函数返回的打开文件.当调用其他多媒体文件I/O函数时，I/O过程可以使用此句柄.

这是一个地址句柄，以便其他程序可以在内存中找到打开的wave文件.关键是，如果要在哪里处理wave文件，则只希望将其打开一次，然后使用其句柄.甚至可以多次播放同一波形文件，而无需每次都从硬盘读取.该句柄将内存中的IO流视为硬盘驱动器IO流.

这是我能想到的最好的答案.

The structure defines a lot of input function. The IOInfo is the return to the function of opening the file.

Handle to the open file, as returned by the mmioOpen function. I/O procedures can use this handle when calling other multimedia file I/O functions.

This is an address handle so that other programs can find the open wave file in memory. The point being if you where to be processing the wave file, you would only want to open it once, and then use its handle. Or even playing the same wave file back multiple times, without reading it from the hard drive every time. This handle treats the IO stream in memory as if it was a hard drive IO stream.

This is the best answer I can think of off the top of my head.
