    First, the sample encoder is MUCH easier to use than what I've already been using (GRip). I don't know if that's because my current method is so terrible or because the new one is so great.

    Second, the resulting files were about 10% smaller. Others may say "so what, hard drives are cheap", but:

    1) I only have 4.5 GB and don't have the extra cash to buy larger.

    2) Larger hard drives make a 10% savings even MORE worthwhile. Consider: If I saved 10% of a 4 GB drive, that's 40 MB--room for maybe 10 additional songs or about one CD. But if I saved 10% of a 400 GB drive, that's an extra 4 GB--enough for 100 CD's.

And to some extent, Linux is often run on old hardware. More so than Windows and certainly more so than Mac. Linux is also free as in beer. Like you, maybe many Ogg users don't have the cash to pay for new hardware. So they don't have the cash/won't spend it on Ogg players either. So they don't sell, so companies don't make them.

    The Tungsten T3 has been widely criticised for poor battery life. My experience has been that I get about 6-7 hours of MP3/Ogg playing time before I get the first low-battery warning. That's pretty equivalent to what you get on an iPod, which won't play Ogg files. Plus the Palm gives you hard buttons, where the iPod has that weird touch-sensitive spinny thing. I have a personal preference for hard buttons, so that was a real winner for me. Other models of Palms have better battery life, and one can increase battery life further by underclocking the CPU, so one can certainly do better than the numbers I've mentioned above. But this was good enough for me.

    Also, the Palm is, of course, a PDA. Bonus, from my point of view, since I needed one. :)

    Cons, of course, are that the Palm's music needs to be placed on a flash card, which means that you're limited to the size of flash cards (I've seen them with capacities up to 512meg, but nothing close to even the low-end iPod's 10gig), the file writing rate of flash cards (very slow).. and so on.

    I tend to fit a bit over two hours of music into 128 meg of space, or more if encoded at a lower bitrate -- I have some old mono radio shows which weigh in at about 6 megabytes for a one hour show, for example. So your 512 meg flash card (or two 256 meg flash cards) will last you for well over a full charge of your battery.

    However (and maybe this is because the Vorbis files emphasize the high frequencies; I'm not sure) the MP3s sound "flat", somehow.

    My understanding of the sound quality difference between MP3 and Ogg Vorbis is that MP3 uses a full Fourier transform (sine, cosine and constant) on the audio, while Ogg Vorbis uses wavelets and does a cosine transform only.

    Discontinuities between blocks sent to the sine transform would cause the Gibbs effect; these would be heard as a garbled low-amplitude reverberation of the high frequency components and transients in the audio. This is consistent with the effects of low bitrate compression; at higher bitrates, there would presumably be more terms used in both the sine and cosine transforms, so the amplitude of the compression artifacts would become smaller and therefore inaudible.

    Cosine transforms, on the other hand, don't have problems with discontinuities, so there'd be an immediate increase in sound quality, at a given bitrate. Transients (attack on cymbals or the rattle of the chain across the membrane of a snare drum, for example) would be handled by wavelet functions - there's probably some sort of mechanism in the code which sees the sharp attack or decay as fast risetimes or falltimes, ignores processing it by cosine transform, and uses wavelets instead.

      Virtually all of the differences between codecs is in the tuning of the psych model, the filters that decide which frequencies to retain and which ones to remove. (it is also the reason there is a HUGE difference between encoders, so when you're comparing an MP3 to an OGG, make sure you use the best encoder for each one if you're trying to compare the merits of each format) There is no simple mathematical function or scientific pricipal behind this, most of the fine tuning is done by trial and error. Because MP3 has the largest user base and has had such a long development time, its psych models are incredibly refined, and for maximum sound quality, LAME encoded MP3 is still one of the best. Of course there are also lots of nasty MP3 encoders out there like Xing (which seems to be what most p2p files are encoded on) which can't compete with Ogg at any bitrate.

      Ogg and ACC are much more modern codecs, with some new coding tricks to increase efficiency, but they have only had a short development time, and the small user bases limit the amount of beta testing/bug reports/ problem samples that can be obtained to fine tune the encoders. Right now, they are much superior to MP3 at low bitrates (due to their increased coding efficiency), but for maximum sound quality, they can't match LAME encoded MP3's.

    But beware, the player is not without it's "quirks":

    "Nice Idea; Poor Execution; Not Ready. Sub-1.0 release. 1 example: Plays MP3-DVDs containing upwards of 1200 songs (files). But device has only a single-line lcd readout & NO FILE BROWSE MODE. What does this mean? Say you want to listen to song #1172... 1. obtain carpal tunnel wrist brace. 2. hit up/forward on remote's jog-diall >> TIMES! (of course if you are a gambling man you could always just put it on random and take side-bets with your friends.) 3. enjoy?"

  27. Linux User - Have Rio Karma 20 by marienf · · Score: 4, Informative

    Just got my Karma yesterday.

    I'd been putting of buying one of these until one appeared that

    - Played Ogg Vorbis
    - Had non-trivial storage capacity in a form-factor what fits my pockets.
    - Had non-trivial autonomy.
    - Management App that ran on Linux, or USB storage device simulation.

    I must say I'm delighted so far. The cradle is plugged in to my stereo and is banging out Mussorgski (New Zealand Symphony Orchestra) with excellent dynamics and clarity.

    I left it on and playing when going to sleep, yesterday evening. When I woke up 6 hours later the battery indicated "half", which is about right for the predicted 15-hour playtime. Of course I don't know if the battery indicator is has been weighed for linearity.

    I've played downloaded (from emusic.com) mp3's and self-ripped Oggs, so far, and they sound just great. I have them cross-faded, and ise nice classic VU-Meters for display.

    After unpacking, connecting to the network (the Cradle has a 100BT connector - the device does DHCP or manual IP setting.) copying the jarball for the "Lite" versions (which is what the Java apps are called) to my laptop, and running it, nothing much worked,at first.

    The app allowed me to delete the pre-stored tracks, and to copy new ones from my HD, but the player would not see them. Also, character translation didn't work very well in the app.
    So In checked out software and firmware versions on the support site, and the ones on the device and CD were hopelessly outdated already.
    After updating both (I had to drive to work to find a Windoze Box.. the updater is an exe file and will not work with Wine) everything was suddenly okay, and I'm now a happy Karma User.

    One downside so far: The included earphones hurt my ears and don't sound too great. Both cushions spontaneously fell off as I was removing the plugs from my ears, and were lost, already.

    "My Karma is Great" :-)
    For what I know from 2 days ownership, I can certainly recommend it. /hrf
