c# - MP3 change bitrate -


i have pre recorded 5 mp3 files @ 320 kbps. in c# using code merge/join them in 1 mp3:

private void mergemp3(list<string> inputfiles, filestream output) {     foreach (string file in inputfiles)     {        mp3filereader reader = new mp3filereader(file);        if ((output.position == 0) && (reader.id3v2tag != null))        {           output.write(reader.id3v2tag.rawdata, 0,    reader.id3v2tag.rawdata.length);        }        mp3frame frame;        {           output.write(frame.rawdata, 0, frame.rawdata.length);        }     } }

the output mp3 file save on disk has bitrate 291 kbps. should have 320 kbps on output file?

edit 1:

the way call function above (mergemp3) main:

    //paths files want merge     list<string> paths = new list<string>();     paths.add(@"c:\users\user\desktop\1.mp3");     paths.add(@"c:\users\user\desktop\2.mp3");     paths.add(@"c:\users\user\desktop\3.mp3");     paths.add(@"c:\users\user\desktop\4.mp3");     paths.add(@"c:\users\user\desktop\5.mp3");     //merge mp3    filestream output = file.open(@"c:\users\user\desktop\alltogether.mp3", filemode.create);    mergemp3(paths, output);

edit 2: using naudio.dll
