117笔记问答在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 = https://www.yisu.com/ask/new byte[1024];> 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。
