    The track/album name might be longer so it uses another frame in the id tag.

      Hi all,

      I was intrigued by this problem when I saw it in the group, so I
      decided to try it myself.

      I use DMC 9a and Winamp 2.23. I couldn't find this problem with
      any of the tracks (and in particular track 11).

      It's a strange one, to say the least.

      This won't help, but I wanted to share my experience....

      Cheers,
      Daren.

        Okay I will post the mp3s

        The Length of the Track is not important because Track 5 is longer than Track 11 and is "normal"
        And both Tracks have Id3v2 (ripped by dmc of course)

        Track 5


        Track 11







        P.S. The Bug only appears when the Bitrate is set to 128kbit/s !!!!
        Maybe this is why daren could'nt find the bug (I use newest Winamp Final 2.8)



        P.S. Mp3Utility says about the 11. Track

        Processing: C:\Dokumente und Einstellungen\Felix\Desktop\Temp\track11.mp3

        Error: Sync error reading frame header 2 expected at byte 1,017. Approx. time: 0:00 (0% through audio).
        Resync failed (no matching frame header found within 2,000 bytes).

        Summary: 1 total frames processed (1 padded, 0 unpadded). Bitrate is constant.

        And mp3gain 0.7.5 also says mpeg 1.0 layer 2

        bye Shaolin

          Winamp says:

          Size: 3957210 bytes
          Header found at: 520 bytes
          Length: 282 seconds
          MPEG 1.0 layer 2
          112kbit, 10840 frames
          44100Hz Stereo
          CRCs: Yes
          Copyrighted: No
          Original: Yes
          Emphasis: CITT j.17

          But in the main Winamp screen, it still says 128Kbps. I'd say it was a bug in Winamp - I'm using 2.8 too.

          EncSpot says 128Kbps MPEG 1 layer 3, though it says the encoder is Gogo 3.0 or higher. Hmmm...

            Do you tested Track 5 or 11?

              This was track 11. I haven't had time to do track 5.

                I also think winamp is buggy (and mp3gain and mp3utility too)
                But what is different on every 11. Track ripped by dmc.. because all other ripped Tracks are "normal" for Winamp usw..

                    EncSpot 1.0 says for both Tracks Lame 3.92 (guess) and mpeg 1 layer 3

                      I was using EncSpot 2.0, which is supposedly more accurate (though I'm surprised at the number of Gogo entries its been giving me that are more likely to be Lame).

                      I think you should report this on the Winamp forums.

                        EncSpot 2.0 also says Lame 3.92..


                        Okay i will post it there but can somebody tell me what is the difference between the 11. and all other Tracks?
                        Because that's important for the bug..

                          Hi all,

                          This is what Winamp 2.23 reports for track 11:

                          Size: 3995270 bytes
                          Length: 399 seconds
                          MPEG 2.5 layer 3
                          80kbit, 7652 frames
                          11025hz Stereo
                          Private: Yes
                          CRCs: Yes
                          Copyrighted: Yes
                          Original: Yes
                          Emphasis: None

                          Freaky, 'cos in the main display I see 128kbps and 44kHz!!

                          Just for the record, I did my own tests at 128kbps VBR (DMC tag
                          editor reports "134kbps"). I just tried again with 128kbps CBR
                          and this still works fine for me.

                          I'm beginning to think it has something to do with the MPEG
                          frame header....

                          I just compared your files with mine using a HEX editor and they
                          look completely different. Did you really make these using DMC 9a
                          + the LAME 3.92 codec???

                          Daren.

                            Heeey,

                            Track 13 from one of my CD's gives this info in Winamp 2.23:

                            Size: 5857317 bytes
                            Length: 243 seconds
                            MPEG 1.0 layer 1
                            192kbit, 9353 frames
                            44100hz Joint Stereo
                            Private: No
                            CRCs: No
                            Copyrighted: Yes
                            Original: Yes
                            Emphasis: invalid

                            For a 128-224kbps VBR.

                            The info starts to get weird after track 10, with slight variations
                            in MPEG version, bitrate, etc...

                            I'll dig into the files with a HEX editor and see if I can get any
                            closer to the reason for the mis-information...

                            Daren.

                              First, yes I make it with dmc 9a and the lame Version that comes with it (I think Lame 3.92)

                              It is very Interesting that every 13. Track (and not 11.) and that it is for you Mpeg 1 Layer 1 and not Mpeg 1 Layer 2 (like for me)

                              I used every Time CBR 128kBit

                              ThanX to you
