    MP3 enhancing sound widget

    Wonder if this is of use to us...

    I'm sure it could integrated quiet nicely into a setup.

    I could see it as very useful but I would like to hear the difference. Not on any high list of mine but I might get one eventually.

    i wonder how they put back the signal that was thrown out...sounds very gimmicky to me.

    thats what i wanna know, it says that they say it will be better quality sound than the CD, or even manufacturing process is..

    how the hell can they do that, unless the little thing just (for lack of a better word right now) stretches the sound down/up the decibel range..

    i'm sure there's an algorithm for inserting missing data based on trends from previous samples and following samples.


    if the data set is

    1 2 3 4 5 6 7 8 9

    and compressed is

    1 3 5 7 9

    so at least for linear data, an averaging calculation i think would prove very accurate. The math for a sine wave is beyond me at present.

    and most audio waveforms are sinusoidal so i think their progressions given data samples are pretty predictable you could recreate data at a specified interval given the trend.

    or 1 2 3 4 5 4 3 2 1


    1 3 5 3 1

    in any case if you were asked to "fill in the blanks" i think it could be easily done.

    before all the mathematicians, statisticians, and audio engineers blast me for speaking as a novice, i'm just submitting this (perhaps oversimplified) idea as a possibility, not as a genuine or refined method of improving sound quality.

    as far as reinforcing high and low frequencies, i think that makes sense. if compression algorithms are tuned to lop off what you're less likely to hear then more of that data is likely to be absent. By my method, the less data you have to work with and the less accurate your sound representation is. I have to imagine though if you're hearing coherent music post-compression to begin with, the refined product would't be any worse than you started with.

    Back to reality though, even if it is possible to redigitize audio at a higher bitrate and fill in the blanks on the fly... how necessary is it? I find 128kbps MP3 encoded files to be quite bright and dynamic. And in an automotive environment, how good can we really expect sound to be?

    Well regular CD's use this sort of thing. Just regular little crumby cd players.
    Its a few different algorithums, LOL my lecturer says its like guessing what the waveform looked like!
