    Have an old VCD, but my sister is only interested in the songs pr the musical part of the VCD.
    I "explore" the VCD, and the layout of its file structure is shown below:

    Thanks...

    The video and audio tracks are in the MPEGAV folder, probably named AVSEQnn.DAT or similar. Try changing the .DAT extension to .MPG and you should have it. You can demux the audio away from the video track with something like the trial version of TMPGEnc. VCD audio is sampled at 44.1Khz while DVD audio is sampled at 48Khz. Likely not a problem for what you want to do.

    Once the audio is extracted, you can do what you want with it, filtering, etc. If needed.

    If you want more information on the VCD format, look to the upper left on this page for 'WHAT IS' VCD.

    There is a file or files in the MPEGAV folder. Probably called "MUSIC01.DAT".

    That is the video file.
    You can just try to copy this to your hard disk and rename it as "music.mpg", it may play as an MPEG1 video.
    There might be glitches though. If so, the best way to extract this is using VCDGear; use its "Extract/convert "dat -> mpeg" function, with "fix mpeg errors" option enabled.

    In either case, then you can extract the audio from the MPEG file.
    You can do this using, eg, Audacity.
    That can open the MP2 audio in the mpg file and then you can save that as MP3 or whatever format you like.

    The MPEGAV file contains





    And I use River Past audio converter to convert each of those .DAT file to MP3, and when I played the converted .d MP3 file, nothing happens....??

  5. Follow AlanHK's instructions. Me, because just renaming them as MPG often introduces artifacts, I always do a proper conversion to MPG before then extracting the audio. You should do the same for each of those DAT files. After getting an MPG I then use DGIndex to extract the audio (where he uses Audacity). Open the MPG in DGIndex and then File->Save Project, which will automatically demux the audio.

    So far, I have use VCDgear to convert the .dat file tp MPEG, I played the converted file using windows media player , and it plays great.
    looked at the 2 programs [ audacity & DGINDEX ]for Audio extraction, butt seem "complicated", was wishing for something easier and effective as well. Thanks

    I hope you're not going to the trouble of transcoding the VCD's audio into MP3. VCD's MP2 is generally decoded properly by MP3 players directly. If you actually transcode into MP3, you lose quality. Just do a straight demux and leave the audio as it is.

    I'm glad you found software you're happy with; TMPGEnc (the free version) has tools for cutting and demuxing, so if you ever want to do those simple operations, that's a nice tool for doing exactly that. The combination of VCDgear and TMPGEnc suffices for the majority of VCD-related tasks.

  10. Actually, Pazera free audio extractor can extract the audio streams without converting it. Just choose the "try extract original audio stream" option in the output format list.
