    Ok, I know what MPEG-1 Layer-3 is (standard, vanilla MP3), but what is MPEG-2 Layer-3? Before you dismiss it, look here:

    (By the way, this is an ARG, which is now over. It finished up with a 5.4 hour audio drama. It's based in the year 2552, in the Halo universe.)

    They are .WAVs, and I thought they were MP3s with a WAV extenstion. But when I checked them in iTunes, I found that they are MPEG-2 Layer-3 files. Also, they are only 56kbps, yet they are quite good quality.

    Why is this the only place I have ever seen MPEG-2 Layer 3? I've never seen it used anywhere else. Also, they played on my iPod, but I didn't know that the iPod supported MPEG-2 Layer 3.

    Is MPEG-2 Layer-3 the format used on DVDs, or do they use something else for audio?

    I thought that 'vanilla' mp3 was mpeg2 layer3... i thoguht that mpeg1's layer3 was just refered to as mpeg1 audio. I must be mistaken?

    Interesting. Thanks. Still, I was surprised at the quality.
