java如何实现把两首MP3一系列的帧进行合并

Answer 1

MP3文件有Header，直接合并文件，会导致MP3无法播放，需要把文件2的Header剔除。请参考以下代码：

         try {
            FileInputStream fistream1 = new FileInputStream(_file_name);
            File f = new File(new File(_file_name).getParent()+"/final.mp3");
            if(!f.exists())
            {
                f.createNewFile();
            }
            FileOutputStream sistream = new FileOutputStream((new File(_file_name)).getParent()+"/final.mp3");
            int temp;
            int size = 0;
            temp = fistream1.read();
            while( temp != -1)
            {
                sistream.write(temp);
                temp = fistream1.read();
            };
            fistream1.close();
            FileInputStream fistream2 = new FileInputStream(temp_file);
            fistream2.read(new byte[32],0,32);
            temp = fistream2.read();
            while( temp != -1)
            {
                sistream.write(temp);
                temp = fistream2.read();
            };
            fistream2.close();
            sistream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
