Bitrate Peeling with Ogg Vorbis

Yort writes "Thought this might be interesting to some audiophile /.ers - there's been some discussion on the Ogg Vorbis lists, summarized in the most recent Ogg Traffic, about "bitrate peeling". In short, it's where you can simply "peel off" the high resolution data from the ends of an audio stream packet to come up with a smaller, lower quality stream. Brings up a number of geek-cool opportunities."

    That may be true if it were peeling off the copyright instead of the bitrate.

    Though it does sound like a pretty cool way to downsample a stream.

    The problem is the pulse width modulation of the quadrature amplitude modulation. Apparently, the loss of Nyquist data near the ends of the audible spectrum causes a noise temperature inversion, which proportionately has an effect on the maximum usable frequency (MUF) of very high frequency waves. This can cause things like distant channel propagation.

    I always kind of felt the first and third bit of every byte were kind of unnecessary. I'm not to fond of the F6 key either!

    "Those who sacrafice sound quality for hard disk space deserve neither."

    Cool idea to throw around though.

    hey you can't polish a turd.

    True story:

    Jerry Lewis sits at an editing console, editing his latest film. Unfortunately he is not happy with the way it is going. Stanley Kubrick stops in, asks is he can watch. Jerry says sure.

    Jerry Lewis (coining the phrase): You can't polish a turd.

    Stanley Kubrick (without missing a beat): You can if you freeze it.

    "On my Complainophile Sony Type-R Limited (bling-bling) audio set up, 32kbps sounds like ass because I didn't realise I could encode at higher bitrates. Except Windows Media because there were no options... then it scanned my hard drive, told me I had really poor taste in music and automatically deleted all my .mp3 files.

    Bitrate peeling is not a good idea because I say so and need to look important. Transcoding is such a better idea because it introduces no artifacts and takes a much shorter time to do. Not that you should do that because nobody uses a narrowband internet connection anymore, at least nobody that I care about. Comparitively RealAudio is great! No, really! I enjoy giving my personal information to someone just so I can listen to commercials and kill pop-up advertising before it asks me if I want to upgrade, then crashes my computer!

    While I conceed it's possible.. nobody else knows what they're talking about! Um... look over there! (exits stage right...)"


    Yes. Thanks. Really persuasive argument.

    Do you always take things people say to ridiculous extremes?

    Er, why do I need to do that, when you say things like this:

    Of course a sound card is useless for listening to music.

    This may come as a shock to you, but the vast majority of people who listen to music on their computers would consider that a ridiculous statement. No extrapolation is necessary on my part - that's a direct quote.

    Note the word listening.

    Wow, I'm so confused as to why I've been playing mp3s on my PC up to now...I thought I was listening to music. Guess not.

    Nice troll yourself :)
