I recently attended to an audiophiles meeting where computers were used as high quality music providers (aka decoder/player).
The best sounding one was a cMP-configured i3, one core disabled and underclocked to optimize the jitter...
The owner of the machine explained us that less workload the computer has, the better able to provide bit-perfect output.
So here's the idea: why don't "put togheter" a MEOS x64 USB distro to easy turn "any" PC into an high quality audio player ?

Idea is good, because it is just small enough to work. There are only some hurdles. Full mp3/ogg support and audio drivers. Format support is easy to do. Audio drivers... not that easy.

Yes, this would be really interesting and I'd love to be involved - maybe helping with the testing or something.
In a proper audiophile distro forget about low-fi tech like MP3. You need to go for a turely lossless way of encoding and storing the sound files. I would suggest using FLAC (free lossless audio codec). Quite a few of the better protable music players use FLAC now, as an option, and Linn audio systems use it. If Linn use it then it must be good.
FLAC codecs/algorithms are open/free of course.
The choice of sound card is going to be important - obviously cheap sound chips built onto a motherboard are not going to hack it for an audiophile application. I would suggest Creative's 'Audigy' because it is readily available at low cost and well enough speceed to be considered 'audiophile'.
I am all for this and would like to be part of seeing this project move forward.

Yeah, but we are talking about a proper audiophile distro, so low-fidelity MP3 support wouldn't really be a requirement would it ?
The required algorithms/codecs to implemet FLAC are readily available but I'm nt too sure about the availability of Ogg Vorbis as so few people use it these days. There's nothing particularly wrong with Ogg Vorbis, per se, but it seems that FLAC is becoming the aceepted standard for high-fidelity in many circles while MP3 is pretty much dominating low-fidelity applications.

Sorry, but the previous post you answered to, kepla, was made by a robot most probably.
The text was copied from my post and some ad-links were suffixed.
I do agree about the FLAC. Once tried to convert some wav-s to mp3, but Winamp
asks money for this conversion. So I made the obvious choice of FLAC. Although
they are huge in size, they can be losslessly unpacked and packed or converted again.

Well, a *true* audiophile distro shouldn't use compressed audio at all (even lossless), 'cause anything that involves computation generates jitter, so lowers the fidelity.
Keep in mind that CMP player loads _whole_ audio data in RAM and plays from it in order to optimize the jitter !!!
So the idea is to *substitute* XP and/or Linux in CMP with a "reduced-optimized" Menuet distro that can lower the jitter even more (by generating less computation).
In the end, we could argue if OVERSAMPLING should be supported or not, but compressed audio is out of question: it's unneeded and goes in the opposite direction (of course we could provide tools to manage it... decoders, for example)

Just to revamp the idea: that friend now switched to Voyage Linux which - he claims - sound better (less weight = more quality).
Another interesting link that may inspire: http://jplay.eu/
They *sells* their player for 99 !
In other words this means that "a market" exist...

So basically a wave player, which keeps the audio in RAM. There already
are .wav and mp3 players available. Also audio midisynth:

Just to "revive the 3ad" here's an open source (MIT licensed) audiophile player for Windows (WASAPI): http://sourceforge.net/projects/playpcmwin/

Hope that inspires !
