PS Audio Music Server In The Pipeline?


#381

It’s only weeks into the new year! 2guns_gifBut, thanks for the nudge. Progress continues, we’ve just integrated Tidal and Qubouz and are working on other streaming services as we can. Hardware continues on a parallel path and I hope we can let a few more people play with the interface in February. No official date yet, but it’s moving along at a decent snail’s pace.

Hi Paul

I discovered the other day that I can use BubbleUPnP to access my music library that is backed up in the Cloud on Microsoft OneDrive.

This solution allows my to listen to all my music without a computer and I find the sound quality very good. What is missing of course is sophisticated media management.

My question is will Bridge 111 be able to mount drives from OneDrive, Google Drive, Dropbox, etc?


#383

Not at present though that shouldn’t be difficult. Is that really practical though? Wouldn’t the latency be onerous?


#384

No actually it works incredibly well I was surprised


#385

Is there some reason that the music server couldn’t rip sacd just as long as they used the same encoding handshake method that is on the DMP via I2S to send it to the Directstream DAC?.

Good question. The reason it can be done in the DMP is that at no point is the full-resolution audio data accessible to the outside world other than via the I2S connector, which I guess the licensors are not concerned about. In the Music Server, the ripped audio data is stored on the internal HD for replay at the user’s convenience. There is no way PS will get a license to do that with SACD content.

Interestingly, for those who don’t know, the main reason ripping SACDs is so darned difficult is not that it is encrypted, per se. The reason is that the spiral of pits in the SACD disc follows a meandering pattern, and the only way to track it properly is if the firmware on the transport is equipped with the code necessary to deal with it. That is not something that can be hacked by your archetypal pimpled geek.


#387

I, for one, was unaware of the meandering pit path. This is indeed interesting.


#388

So you are saying that chip can’t be used on the back side of the digital data? Or Sony won’t let that kind of SACD data be stored on a hard drive? Or PS Audio won’t spend that kind of money to do that since they have a solution for SACD with the DMP? I never knew that they had that kind of stuff with the pits on the SACD disc. Very interesting. The music server is going to have a disc transport built in it right?


#389

I guess there’s no legal way to play SACD from the server, as then it would have to have a DMP integrated, which would probably double its price.

That level of specific detail I am not familiar with. I imagine the command(s) that allow the transport to read the SACD layer are all you would need to then store the resultant data on a HD, but of course that would get PS into all sorts of legal trouble if they chose to implement it.

Ted Bailey posted instructions last year for modifying an Oppo or Pioneer BD player to enable users to rip SACDs to disc. Since it appears to make use of a flaw in a specific series of transports rather than in Oppo/Pioneer’s implementation, I expect those companies are not having to contend with any legal blow-back. It’s a long thread, and I haven’t bothered to follow it to the end.

Another approach would be to design and build an I2S-to-USB converter, and insert that between a DMP and a computer. I don’t know if such things exist.

I believe the Music Server will ship with a CD transport, rather than a SACD transport. Maybe Paul will comment.


#391

Richard’s correct. The server will ship with a DVD/CD ripper installed as of this date. If we included a BluRay disc ripper and the ability to rip SACD onto a hard drive we would be in direct violation of Sony Copyright something we would not ever do without getting permission. If I put my clever cap on I could imagine figuring out a way to keep some sort of encryption on the hard drive so once ripped it could not be removed or copied and adding the same handshake requirements we have now and SACD playback available to only PS Audio DACS and only through I2S and that might satisfy their requirements. And it might not.

No plans currently exist to do all that work and risk rousing the sleeping bear.

Kaleidescape can rip a bit perfect copy of a BR disc to a Kaleidescape server, all perfectly legitimate within their closed ecosystem. Just can’t do that for a SACD unfortunately.

#393

Exactly. And that is because each SACD has a unique encryption code that must be decoded by a Sony chip. If you use a Sony chip and then somehow make the unencrypted file public, you are in violation of their copyright. Which is why the DMP, using the internal Sony Chip to decode the encrypted file, restricts the copying of that file and makes it impossible to make copies. If Kaleidoscape were to copy those files using a Sony chip to decode the encryption they would be in hot water.


#394
brodricj said Kaleidescape can rip a bit perfect copy of a BR disc to a Kaleidescape server . . .
As I recall, Kaleidescape can only play an approved copy of a DVD as downloaded from Kaleidescape's system and on a user's hard drive only if a physical copy of the hard drive is present in an attached Kaleidescape "Vault" of disks). That is, you can only play the copy off of the drive if the DVD is also physically present.

Does the playback of Blu-ray disks work differently in the Kaleidescape environment?


#395

Will the music server be able to store my downloaded .dsf files so that I have only one place to go to play my music? Will it be able to play my SACD/ DSD music? SACD rips?


#396

Yup. Should not be a problem.


#397

Just noticed that this topic falls under “Everything Else” and “Humor”. Humor? Someone could read more into this than intended, perhaps a correction of the category is in order?


#398

Thank you for noticing this! I moved the thread to a better location.


#399

Personally I loathe playlists, and would strongly prefer a system that adapts to my preferences, expressed as Like/Hate buttons.
Playlists take an inordinate amount of time to create and after the first few plays, become boring and predictable. I want to hear music that is new to me as part of a personalized mix.
AFAIC, creating playlists should be done by a personalization algorithm or a disk-jockey, not by me.

I very much agree with your take on this Eldrick. Playlists are dreadful to create and get boring quickly. Predictive AI/algorithms are where its at, in my opinion.
