“Java的声音教程，但不知怎么的，对初学者来说太复杂了。”哪种语言听起来“简单”？+1这些教程针对的是有一定经验的人。教程应该是这样，如果这是复杂的，我怀疑任何其他教程将更好。我建议你试着去看看你能得到什么。您要检测的步骤1已明确说明。只需运行代码。如果代码失败，请返回并询问更具体的问题。也许这更符合您的要求：

Via command-line arguments the user specifies whether * audio (-a) or video (-v) capture, the duration of the capture (-d) in * seconds, and the file to write the media to (-f). * * The application would be far more useful and versatile if it provided control * over the formats of the audio and video captured as well as the content type * of the output. * * The class searches for capture devices that support the particular default * track formats: linear for audio and Cinepak for video. As a fall-back two * device names are hard-coded into the application as an example of how to * obtain DeviceInfo when a device's name is known. The user may force the * application to use these names by using the -k (known devices) flag. * * The class is static but employs the earlier Location2Location example to * perform all the Processor and DataSink related work. Thus the application * chiefly involves CaptureDevice related operations. * * @author Michael (Spike) Barlow ******************************************************************************/ public class SimpleRecorder { ///////////////////////////////////////////////////////////// // Names for the audio and video capture devices on the // author's system.
