在网上搜索alaways找到用c ++或mfc编写的代码。那是为95号窗口写的，我想知道是否可以在windows Media Player上录制一个声音文件，如果有的话请帮我提一下这个代码的提示或链接，如果不是直接指示我的任何短片代码（在c＃中）

推荐答案

不，音频文件格式和压缩算法不是由文件名extensions定义的。有不同的编解码器，流，它们托管在不同容器格式的文件中;这件事可以结合起来。要了解相关信息，请参阅： http://en.wikipedia.org/wiki/Digital_container_format [ ^ ]。



对于录音，有限但最简单的方式，你可以看到我的文章实用录音机声音激活 [ ^ ]。



产生.wav格式。然后你可以重新掌握它到任何其他，* .mp3或* .wma。我建议你使用可用的库甚至命令行实用程序，开源libav或FFMpeg。请查看我过去的答案：

你可以做更多复杂的事情，自己数字化声音，动态压缩，以及更多。请记住，这是非常复杂的事情（不是原则，而是由于大量的知识和各种所需的标准和选项），并且意味着大量的工作。

No, audio file formats and compression algorithms are not defined by the file name "extensions". There are different codecs, streams, and they are hosted in a file of different container formats; this things can combine. To get an idea, please read: http://en.wikipedia.org/wiki/Digital_container_format[^].

For sound recording, limited but simplest way, you can see my article Practical Sound Recorder with Sound Activation[^].

That produces .wav format. Then you can re-master it to any other, *.mp3 or *.wma. I would recommend you to use available library or even command-line utility, open-source libav or FFMpeg. Please see my past answers:
How to trim the video using Directshow!?[^],
how to convert image to video in C#[^],
HTML5 and Mime, Streaming a video?[^].

You could do a lot more sophisticated things, digitize sound by yourself, do the compression on the fly, and a lot more. Just remember that it is quite complicated matter (not by principles but rather due to a big volume of knowledge and variety of required standards and options) and would mean a huge amount of work.
