本代码将调用javax.sound库，讲解音频输入流的使用 得到音频输入流可无阻塞地读取（或跳过）的最大字节数、音频输入流里声音的音频数据格式、音频输入流的帧长度 本文可作为javax.sound学习指南，javax.sound学习实战等进行参考 相关内容请看下方代码与注释
import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import java.io.File;
public class SoundInputStream {
//音频输入流相关===========================================================
//保存音频输入流
public static AudioInputStream soundInputStream = null;
//保存音频输入流可无阻塞地读取（或跳过）的最大字节数
private static int soundInputStreamMaxByte;
//保存音频输入流里声音的音频数据格式
protected static AudioFormat soundInputStreamSoundDataFormat = null;
//保存音频输入流的帧长度
private static long soundInputStreamFrameLength;
//清空所有内容，释放内存
protected static void clearAll(){
soundInputStream = null;
soundInputStreamSoundDataFormat = null;
}
//获取音频输入流
public static void getSoundInputStream(File soundFile) throws Exception {
soundInputStream = AudioSystem.getAudioInputStream(soundFile);
soundInputStreamMaxByte = soundInputStream.available();
soundInputStreamSoundDataFormat = soundInputStream.getFormat();
soundInputStreamFrameLength = soundInputStream.getFrameLength();
}
public static void showSoundInputStream() throws Exception {
System.out.println("音频输入流可无阻塞地读取（或跳过）的最大字节数为：" + soundInputStreamMaxByte + " byte 即 " + soundInputStreamMaxByte / 1024.0 + " kb 或 " + soundInputStreamMaxByte / 1024.0 / 1024 + " mb");
System.out.println("音频输入流里声音数据的音频格式为：" + soundInputStreamSoundDataFormat);
System.out.println("音频输入流的帧长度为：" + soundInputStreamFrameLength + " frame");
System.out.println("==============");
}
