Java中如何实现声音的录制与播放

在Java中实现声音的录制与播放可以使用JavaSound API。以下是一个简单的示例代码：

录制声音：

import javax.sound.sampled.*;  public class AudioRecorder {      public static void main(String[] args) {         try {             AudioFormat format = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED, 44100, 16, 2, 4, 44100, false);             DataLine.Info info = new DataLine.Info(TargetDataLine.class, format);             TargetDataLine line = (TargetDataLine) AudioSystem.getLine(info);             line.open(format);             line.start();              AudioInputStream ais = new AudioInputStream(line);              AudioSystem.write(ais, AudioFileFormat.Type.WAVE, new File("audio.wav"));              line.stop();             line.close();          } catch (LineUnavailableException | IOException e) {             e.printStackTrace();         }     } } 

播放声音：

import javax.sound.sampled.*;  public class AudioPlayer {      public static void main(String[] args) {         try {             AudioInputStream ais = AudioSystem.getAudioInputStream(new File("audio.wav"));              AudioFormat format = ais.getFormat();             DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);             SourceDataLine line = (SourceDataLine) AudioSystem.getLine(info);              line.open(format);             line.start();              byte[] data = new byte[1024];             int bytesRead = 0;              while ((bytesRead = ais.read(data, 0, data.length)) != -1) {                 line.write(data, 0, bytesRead);             }              line.drain();             line.close();          } catch (UnsupportedAudioFileException | LineUnavailableException | IOException e) {             e.printStackTrace();         }     } } 

在上面的示例代码中，AudioRecorder类实现了声音的录制，将录制的声音保存为一个WAV文件；AudioPlayer类实现了声音的播放，从录制的WAV文件中读取声音数据并进行播放。
