Re: [slim] can SB do lossless FLAC 5.1?

2008-05-21 Thread ntom

Many DVD-A discs have a hi-res stereo mix as well as 5.1 surround mix
which can be extracted directly to WAV

(though obviously lose benefit of surround mixes...!!)

Re: [slim] can SB do lossless FLAC 5.1?

2008-05-18 Thread Eric Seaberg

OK... I've done it!! An 'un-named' user sent me the link to rip MLP
DVD-As as WAV files.  The way it actually works is to pull a
LF/RF/LS/RS (Quad) file and separate C/LFE file.  

The files are ripped on a Apple MacBook Pro using Parallels (running
Windows as a separate app) since the ripping app is Windows based. 

I import these files into ProTools (Mac), which 'un-wraps' them into
individual 96k/24bit mono files.  I then encode them all as a 96k DTS
encoded WAV file and VIOLA!!!  It plays and can, certainly, be encoded
lossless as FLAC to save bandwidth.

Anyhow... IT WORKS!!

There's an app I use in production of 5.1 Dolby and DTS, but it works
with ProTools and does cost $1000 just for the plugin...probably NOT
really on the affordable side, eh?

I'd love to know HOW you're ripping MLP audio from DVD-A?  Maybe we
could work out a 'trade' where I'll encode your WAV files to DTS if you
rip some of my DVD-A that don't have a Dolby/DTS playlist on them. 
That's the ONLY way I've been able to do it so far, is by extracting
Dolby or DTS, but not the lossless.

Re: [slim] can SB do lossless FLAC 5.1?

2008-05-15 Thread ntom

I've started trying to rip audio from a few DVD-A discs that I have. 
Seem to have managed to rip the 24/96 stereo mix OK.  Also ripped the
24/96 5.1 mix OK.  The stereo mixs streams to my SB3 OK.  The 5.1 mix
doesn't -guess no surprise.  Just wont play -thought maybe i could pass
SPDIF to a surround amp but even if it had played I guess would have
been no good as not DT or DD.

Is there anything that would allow me to encode the 5.1 WAVs to DTS (at
a sensible costI dont have many DVD-A discs!!)

As a DVD-A it also carries the DVD-V Dolby Digital mix so I guess this
would be the next best option to stream to SB3  feed SPDIF to my

Its more a lack of interest by the industry. Even the RIAA knows that 
DRM is a loser.

The key part is Tim's
A consumer standard IS possible, but given

The record industry (really the big labels) don't want consumers to have

Huh? The majors haven't sold anything analog in years...and if you look
at the world of video the copyright holders are forcing a move away from
analog (component) to digital (hdmi) in order to add DRM.

Yeah, that is their claim, analog is bad, digital with DRM is good.

I think Pat's referring to post-CD digital formats such as SACD and
DVD-A.  If I understand correctly, Sony mandated that no consumer SACD
player would output an unencrypted digital signal.  And DVD-A defines a
down-sampled unencrypted digital output.  All ways the industry
attempts to keep the digital information locked up on the disc and give
you access to only an analog output.

The average consumer seems quite content to live with analog
interconnection.  Since consumers, by and large, aren't asking for it,
and the industry doesn't seem to want it anyway, I think the
motivations are AGAINST developing and/or deploying multichannel
digital interconnection.  HDMI *may* continue to gain ground, not
because it's digital, but because it eliminates to rats-nest of analog
cables.

So far as DRM, the only legitimate thorn in the industry's side is
consumer's desires to rip content for their iPods.  Apple has so far
been somewhat successful at putting their fingers in the DRM dike with
the tight integration of the ITMS, so DRM concerns are handled
automagically.  But market forces, such as Amazon's non-DRM MP3's,
Micrsoft turning off the plays for sure authorization servers, and
the number of people who have non-Apple MP3 players are starting to
breach the industry's DRM dike.  However, I'll be surprised if this
has any effect on multichannel and/or HiRes DRM anytime soon...

Right, red book was invented before computers. At least it sure seems 
like that, they could have trivially added stuff to make it far better, 
but it was a major improvement when direct Digital Audio Extraction 
became possible.

 player would output an unencrypted digital signal.  And DVD-A defines a
 down-sampled unencrypted digital output.  All ways the industry
 attempts to keep the digital information locked up on the disc and give

Of course, they failed. There was always the analog loophole where all 
you need is a six channel PCM audio card running at 88.2 or 96 kHz
to make digital copies that are indistingishable from the original. 
Assuming of course, that the SACD or DVD-A actually had something other 
than Red Book audio on them in the first place.

 The average consumer seems quite content to live with analog
 interconnection. 

Sadly the average consumer has no clue what audio quality is.

I think a more fundamental problem with multi-channel for audio 
(separate from movie soundracks) is that there is no standard mix, so 
even if you could get 5 audiophile speakers in the room (talk about zero 
WAF) you don't and can't know where to place them.

If I had been king of audio, I'd have said the standard is two big 
front speakers, a subwoofer and two (or three) spacial ambience speaker.
The spacial speakers do not have to be full range.

I have exactly the same problem as you.

I even had to reboot by NAS (I'm using SSODS 3.0b10 with SqueezeCenter
7.0) to be able to play again some music on my SqueezeBox 3.

I am naive in this arena, but wouldn't HDMI solve this problem without
trying to build a new standard?  Granted, current-gen Logitech devices
wouldn't support it but in the future it seems like HDMI would be the
easiest way to build multichannel audio support into a device like this.

[slim] can SB do lossless FLAC 5.1?

2008-02-03 Thread redil

Hello Forum,
after having ripped all my Redbook CD, I am only left with a stack of
SACD (and DVD-A). Now, some labels provide 24/48 highres 5.1 FLAC and
WAV classical music for download. So that would be the way to go to
also be able to use the SB for SACD quality music. The problem is that
the downloaded sample from the website blows the SB, it hangs with ran
out of decoder memory and has to be hard reset.
My question is: is the SB SUPPOSED to process this stream (DTS works
fine on my system). Also WAV of the same music does not work, it does
not hang the system, but simply loops over the first 5 or so seconds.
No sound coming out.

Any idea?

Redil
