Xing Frame

In some MP3s which variable bit rate the first frame in the file contains a special frame called a Xing Frame, instead of audio data. This is used to store additional information about the file. The most important aspect for this library is details allowing us to determine the bitrate of a Variable Bit Rate VBR file without having to process the whole file.

Xing VBR Tag data format is 120 bytes long 4 bytes for Header Tag 4 bytes for Header Flags 4 bytes for FRAME SIZE 4 bytes for AUDIO_SIZE 100 bytes for entry (NUMTOCENTRIES) 4 bytes for VBR SCALE. a VBR quality indicator: 0=best 100=worst

It my then contain a Lame Frame ( a Lame frame is in essence an extended Xing Frame

            copyHeaderFields(mp3AudioHeader, track);


            long totalSamples = trackData.getTotalSamples();
            int enc_delay = GAPLESS_DELAY;


            XingFrame xingFrame = mp3AudioHeader.getXingFrame();
            if (xingFrame != null) {
                LameFrame lameFrame = xingFrame.getLameFrame();
                if (lameFrame != null) {
                    long length = totalSamples;
                    enc_delay += lameFrame.getEncDelay();
                    int enc_padding = lameFrame.getEncPadding() - GAPLESS_DELAY;
                    if (enc_padding < length)
