问题描述

我正在写一个Windows应用程序，可以让人们做一些类似于在抓屏。我的一个应用程序需要以允许的事情是捕捉由在计算机上的其他应用程序正在产生的音频，将其添加到记录。一些谷歌搜索表明，新WASAPI实际上支持做这样的东西，但仅适用于Windows Vista和Windows 7提供，而我的目标市场的大部分运行Windows XP中。

I'm writing a windows application that lets people do something akin to screencasting. One of the things my application needs to allow is to capture the audio being produced by the other applications on the computer to add them to the recording. Some googling indicates that the new WASAPI actually supports doing stuff like this, but is only available on windows vista and windows 7, and a large portion of my target market runs windows xp.

推荐答案

它看起来像这里唯一的解决方案，在Windows XP上的作品是写一个音频驱动程序，使该公司发送给它提供给用户级音频。幸运的是谁家已经完成这个（ http://software.muzychenko.net/eng/vac.htm）。不幸的是，他收款。

It looks like the only solution here that works on windows xp is to write an audio driver that makes the audio that's sent to it available to userland. Fortunately someone's already done this ( http://software.muzychenko.net/eng/vac.htm ). Unfortunately he charges money.
