连接两个音频文件并播放产生的文件音频文件、两个、文件

2023-09-05 01:50:09 作者:耍硪ミ倪配么

我真的面临着最后几天的问题,但我不能找到确切的解决方案,请帮助我。

我想合并两个mp3或者任何音频文件并播放最后的单一的mp3文件。但是,当我合并两个文件的最终文件大小是确定的,但,当我试图发挥它只是起到第一个文件,我曾试图与的SequenceInputStream 或字节数组,但我我无法得到确切的结果,请帮助我。

我的code是如下:

 公共类MerginFileHere延伸活动{

            +/AudioRecorder/one.mp3;

            //fos.write(fileContent1);//写字节到合并文件中。


            byte []的组合=新的字节[fileContent.length + fileContent1.length]。

            的for(int i = 0; I< combined.length ++ I)
            {
                结合[I] = I< fileContent.length? fileContent [我]:fileContent1 [我 -  fileContent.length]。

解决方案

我已经出版了此功能的应用程序...试试我的方法使用的SequenceInputStream,在我的应用程序,我只是合并在一个17的MP3文件,并通过播放JNI库MPG123,但我测试用MediaPlayer的没有问题的文件。

这code是不是最好的,但它的工作原理...

 私人无效mergeSongs(文件mergedFile,文件... mp3Files){
        的FileInputStream fisToFinal = NULL;
        FileOutputStream中FOS = NULL;
        尝试 {
            FOS =新的FileOutputStream(mergedFile);
            fisToFinal =新的FileInputStream(mergedFile);
            对于(文件mp3File:mp3Files){
                如果(!mp3File.exists())
                    继续;
                的FileInputStream fisSong =新的FileInputStream(mp3File);
                的SequenceInputStream SIS =新的SequenceInputStream(fisToFinal,fisSong);
                byte []的BUF =新的字节[1024];
                尝试 {
                    对于(INT readNum;(readNum = fisSong.read(BUF))= -1;!)
                        fos.write(BUF,0,readNum);
                } 最后 {
                    如果(fisSong!= NULL){
                        fisSong.close();
                    }
                    如果(SIS!= NULL){
                        sis.close();
                    }
                }
            }
        }赶上(IOException异常E){
            e.printStackTrace();
        }最后{
            尝试 {
                如果(FOS!= NULL){
                    fos.flush();
                    fos.close();
                }
                如果(fisToFinal!= NULL){
                    fisToFinal.close();
                }
            }赶上(IOException异常E){
                e.printStackTrace();
            }
        }
    }

I am really facing problem from last couple of days but I am not able to find the exact solution please help me.

I want to merge two .mp3 or any audio file and play final single one mp3 file. But when I am combine two file the final file size is ok but when I am trying to play it just play first file, I have tried this with SequenceInputStream or byte array but I am not able to get exact result please help me.

My code is the following:

public class MerginFileHere extends Activity {
public ArrayList<String> audNames;
byte fileContent[];
byte fileContent1[];
FileInputStream ins,ins1;
FileOutputStream fos = null;
String combined_file_stored_path = Environment
        .getExternalStorageDirectory().getPath()
        + "/AudioRecorder/final.mp3";

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);
    audNames = new ArrayList<String>();
    String file1 = Environment.getExternalStorageDirectory().getPath()
            + "/AudioRecorder/one.mp3";

    String file2 = Environment.getExternalStorageDirectory().getPath()
            + "/AudioRecorder/two.mp3";

    File file = new File(Environment.getExternalStorageDirectory()
            .getPath() + "/AudioRecorder/" + "final.mp3");

    try {
        file.createNewFile();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    audNames.add(file1);
    audNames.add(file2);

    Button btn = (Button) findViewById(R.id.clickme);
    btn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            createCombineRecFile();
        }
    });
}

public void createCombineRecFile() {
    // String combined_file_stored_path = // File path in String to store
    // recorded audio

    try {
        fos = new FileOutputStream(combined_file_stored_path, true);
    } catch (FileNotFoundException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }

        try {
            File f = new File(audNames.get(0));
            File f1 = new File(audNames.get(1));
            Log.i("Record Message", "File Length=========>>>" + f.length()+"------------->"+f1.length());


            fileContent = new byte[(int) f.length()];
            ins = new FileInputStream(audNames.get(0));
            int r = ins.read(fileContent);// Reads the file content as byte

            fileContent1 = new byte[(int) f1.length()];
            ins1 = new FileInputStream(audNames.get(1));
            int r1 = ins1.read(fileContent1);// Reads the file content as byte
                                            // from the list.






            Log.i("Record Message", "Number Of Bytes Readed=====>>>" + r);

            //fos.write(fileContent1);// Write the byte into the combine file.


            byte[] combined = new byte[fileContent.length + fileContent1.length];

            for (int i = 0; i < combined.length; ++i)
            {
                combined[i] = i < fileContent.length ? fileContent[i] : fileContent1[i - fileContent.length];
            }
            fos.write(combined);
            //fos.write(fileContent1);*



        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    try {
        fos.close();
        Log.v("Record Message", "===== Combine File Closed =====");
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
}

I already published an app with this function... try my method using SequenceInputStream, in my app I just merge 17 MP3 files in one and play it using the JNI Library MPG123, but I tested the file using MediaPlayer without problems.

This code isn't the best, but it works...

private void mergeSongs(File mergedFile,File...mp3Files){
        FileInputStream fisToFinal = null;
        FileOutputStream fos = null;
        try {
            fos = new FileOutputStream(mergedFile);
            fisToFinal = new FileInputStream(mergedFile);
            for(File mp3File:mp3Files){
                if(!mp3File.exists())
                    continue;
                FileInputStream fisSong = new FileInputStream(mp3File);
                SequenceInputStream sis = new SequenceInputStream(fisToFinal, fisSong);
                byte[] buf = new byte[1024];
                try {
                    for (int readNum; (readNum = fisSong.read(buf)) != -1;)
                        fos.write(buf, 0, readNum);
                } finally {
                    if(fisSong!=null){
                        fisSong.close();
                    }
                    if(sis!=null){
                        sis.close();
                    }
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        }finally{
            try {
                if(fos!=null){
                    fos.flush();
                    fos.close();
                }
                if(fisToFinal!=null){
                    fisToFinal.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
