Java 如何阅读MP3
使用我能够找到如何阅读mp3文件,但我仍然对如何实际使用它感到困惑Java 如何阅读MP3,java,mp3,Java,Mp3,使用我能够找到如何阅读mp3文件,但我仍然对如何实际使用它感到困惑 File file = new File(filename); AudioInputStream in= AudioSystem.getAudioInputStream(file); AudioInputStream din = null; AudioFormat baseFormat = in.getFormat(); AudioFormat decodedFormat = new AudioFormat(AudioForma
File file = new File(filename);
AudioInputStream in= AudioSystem.getAudioInputStream(file);
AudioInputStream din = null;
AudioFormat baseFormat = in.getFormat();
AudioFormat decodedFormat = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED,
baseFormat.getSampleRate(),
16,
baseFormat.getChannels(),
baseFormat.getChannels() * 2,
baseFormat.getSampleRate(),
false);
din = AudioSystem.getAudioInputStream(decodedFormat, in);
在这些声明之后,如何使用din
?我知道循环看起来是这样的:
while (/*What do I put here??*/){
int currentByte = din.read();
}
换句话说,我只是问如何从mp3文件中读取整个字节数组,在循环中一次检查一个字节。AudioInputStream.read(),这样在发生这种情况时,您就可以中断循环:
while (true){
int currentByte = din.read();
if (currentByte == -1) break;
// Handling code
}
请尝试以下代码:
导入java.io.DataInputStream;
导入java.io.FileInputStream
public class Main {
public static void main(String[] args) throws Exception {
FileInputStream fin = new FileInputStream("C:/Array.txt");
DataInputStream din = new DataInputStream(fin);
byte b[] = new byte[10];
din.read(b);
din.close();
}
