使用Java錄製語音

Question

我想使用Java應用程序錄制語音;我想這將基本上是一個將在客戶端運行的applet。但我不知道如何去做......任何想法？另外，我想播放錄製的聲音。

我聽說過Java Speech API。任何想法，如果它可以幫助？

我遲到了，但這裏有上捕獲音頻的官方文檔：http://docs.oracle.com/javase/tutorial/sound/capturing.html

（直接從上面這裏的鏈接複製是一些示例代碼做到這一點:)

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); 
}
