In Java, how do I record the sound output that is going to the speakers?
提问by Matt
I have a java application that is taking in sound from multiple sources, and one of the abilities of the user is to record what is happening in the application to an AVI file, and I would like to include the sound in that video capture. How do I record the sound that the user would hear (ex. a result of all of the sound inputs mixed together)? I can figure out how to get the actual sound stream in to the video, but I am not sure where to get that sound source from.
我有一个从多个来源接收声音的 Java 应用程序，用户的一项能力是将应用程序中发生的事情记录到 AVI 文件中，我想在该视频捕获中包含声音。如何录制用户会听到的声音（例如，所有声音输入混合在一起的结果）？我可以弄清楚如何将实际的声音流输入到视频中，但我不确定从哪里获得该声源。
