[英]Record voice with Java
I want to record voice using a Java application; 我想用Java应用程序录制语音; I guess this will be basically an applet that will run on client side.
我想这基本上是一个将在客户端运行的applet。 But I don't have any idea of how to do it... any ideas?
但我不知道该怎么做......任何想法? Also, I want to play the recorded voice.
另外,我想播放录制的声音。
I have heard of Java Speech API. 我听说过Java Speech API。 Any idea if it can help?
有什么想法可以提供帮助吗?
I am late to the party, but here are the official docs on capturing audio: http://docs.oracle.com/javase/tutorial/sound/capturing.html 我迟到了,但这里有关于捕获音频的官方文档: http : //docs.oracle.com/javase/tutorial/sound/capturing.html
(And copied directly from the link above here is some sample code to do it:) (并直接从上面的链接复制这里是一些示例代码:)
TargetDataLine line;
DataLine.Info info = new DataLine.Info(TargetDataLine.class,
format); // format is an AudioFormat object
if (!AudioSystem.isLineSupported(info)) {
// Handle the error ...
}
// Obtain and open the line.
try {
line = (TargetDataLine) AudioSystem.getLine(info);
line.open(format);
} catch (LineUnavailableException ex) {
// Handle the error ...
}
// Assume that the TargetDataLine, line, has already
// been obtained and opened.
ByteArrayOutputStream out = new ByteArrayOutputStream();
int numBytesRead;
byte[] data = new byte[line.getBufferSize() / 5];
// Begin audio capture.
line.start();
// Here, stopped is a global boolean set by another thread.
while (!stopped) {
// Read the next chunk of data from the TargetDataLine.
numBytesRead = line.read(data, 0, data.length);
// Save this chunk of data.
out.write(data, 0, numBytesRead);
}
