I personally would prefer 48/24/5.1 over 96kHz/16-bit/5.1, for me the 24 bits make a big difference while the 96kHz while not wasted really gives diminishing returns compared to 48kHz.
The PS3 must be the best machine for those who dare handle a computer, the DVICo (or similar, several companies are coming with media extenders built on the same chip - but no other seems to care that much about audio...) for those not wanting the complexity of a computer.
I would have bought a PS3 long time ago if it had 5.1 analogue out (or if my Meridian G68 had HDMI in...), right now I'm waiting for more info on USB in for Meridian processors.

> Lastly, I think the DVD-Audio spec allows 96kHz/16-bit/5.1ch LPCM .bin audio as well (no MLP). Maybe a tool that bit-dithers from 24 to 16 would be a nice addition. This would have a bit-rate of 9.22 Mbps compared to 6.91 Mbps for 48kHz/24-bit/5.1. Not sure which would sound better.

> It should be mentioned that with the PS3's down to around $399 now, you can look at it as a cheap media extender / media server/ HTPC thingy. First, the adventurous can burn their own BluRays that will play all the HD audio formats. Second it is kinda of like the first A/V videocard/soundcard since it can play HD video and audio together out the HDMI connector. It has been devilish to find the limitations of the XMB media player, but I have played 1080p at 25MBps with 448kbps 5.1 AC-3 from the HD and it is pretty. I am trying to find the true limitations of the formats that can be played, but I don't have a HDMI receiver right now. I'm pretty sure I can find a way to mux up MPEG-2 with LPCM, but at what sample rate, bit depth and number of channels. What would be cheaper than this solution, the TVix : M-6500A in a year?

DVICo however thinks that when the first batch of 6500's is released in January (?) the Firmware will not be ready for this, it will come in a later FW upgrade. But DVICO has a good track record for FW upgrades.Matroska info is found at http://www.matroska.org/

There are also a lot of limitations at this time (48k only,> SPDIF/toslink only) though this is improving rapidly (PS3 firmware 2.0> finally allows XMB to output 5.1).> > Thanks in advance,> BAC> > > -------------- next part --------------> An HTML attachment was scrubbed...> > ------------------------------> > -------------------------------------------------> ------------------------> This SF.net email is sponsored by: Microsoft> Defy all challenges.
