New Lossless MP3 Format Explained

CNETNate writes "Thomson, the company that licenses the MP3 patent, has released a new lossless MP3 format called mp3HD. It utilises both lossless and lossy audio contained inside a single .mp3 file, and the files will play on all existing MP3 players. The idea is simple: lossless files on your desktop that can be transferred without conversion to iPods and MP3 players. The issue, it transpires, is that although the full lossless/lossy hybrid MP3 file is transferred to players, only the lossy element can be played back. A command line encoder can be found on Thomson's Web site."

  1. The stupidest format ever! by Per+Wigren · · Score: 5, Interesting

    Basically it's a standard MP3 with correction delta as a binary blob in the ID3-tag. Was it really that hard to make it interleaved? Even having the correction data as a separate file, like Wavpack does it in its hybrid mode, would be better as it would make it much easier to add the files to MP3-players without using extra tools. This is just stupid. You won't be able to stream it as it's not interleaved and ID3 tags are limited to 256 MB so you can't have a MP3HD-file longer than 35 minutes or so.

    I think an even better comparison would be a car with a helicopter stapled to the trunk. That's not even right, since the car & helicopter are more analogous to the ipod and computer. This is more like everything you would put in your car has a 10:1 scale model of itself attached to it.

    Its like every shirt in Arizona having a winter coat sewn to the back of it. Closets hold 1/10 as many clothes, but big closets are getting cheaper every day. The largest suitcases barely hold enough for a weekend trip. Everyone ends up dragging around winter coats like tails, even though they rarely ever need them.

    My analogy is bad, but not as bad as this hybrid mp3 format. I suppose the format is OK for archival storage, but copying the huge files to a portable device with limited space is just stupid.

    Not to mention there is a REASON why they are coming out with this now, and it AIN'T because they want you to have high fi MP3s. It is because the MP3 patents expire in Dec 2012 so they are hoping to get all the MP3 makers and home users switched over so they can keep drawing a check.

    And the simple fact is thanks to the loudness war trying to come up with high fi MP3 is about as pointless as coming up with a super polished turd. The extra bitrate will NOT be any better than the 320k we have now, simply because the source material is so shitty. In fact most folks I know use 128K VBR because they can't tell the difference. So don't be fooled, this is NOT to make your music sound better. It is so they can keep MP3 compression under patents for another 20+ years. I don't know about you but I would rather stick to good old MP3 and wait to see what kind of cool new gadgets come out in 2013 when the patents pass. Plus having legal Linux support is a nice bonus too.

    ...is MP3FS, a virtual file system that transcodes your FLAC files to MP3 on the fly (including metadata).

    Just keep all your FLAC files on PC or NAS, and when you want to load them on a player, copy them from the MP3FS directory.

    You don't need to keep duplicate lossy files around, and you don't have huge chunks of lossless music taking up space on a player that can't play them anyway.
