Re-authoring a SACD

[gfv]

I hear about extracting DSD files from a SACD ISO image file and
converting to PCM. I also hear about converting PCM files to DSD and
authoring a SACD. Are tools readily available to extract stereo DSD
files from more than one SACD ISO and then re-author a stereo only
SACD ISO image to burn to DVD+R? The idea is to combine two SHM-SACD
ISO images onto one DVD+R with no processing of the audio data.

Thanks in advance.

Yes, its quite possible... and has been done.  That said, its not point and click... but also not terribly difficult.  It does however require multiple programs.  There is a program to extract DFFs from ISOs and then another to compile those into a new disc.  I don't personally use the programs.  That said, I do know that guides are being made.  Hopefully someone will email you with more explicit details.

To extract DSD files from an SACD, use scarletbook.

[Jack Dawson Sparrow]

Can i send, from my computer, a DSD file to be decoded by my receiver,
via Spidif?

I'm quite not into re-authoring SACDs but afaik the workflow is as
follows:
1) Scarletbook or sacd_extract: SACD-R iso -> uncompressed DSD tracks
2) Number the DSD tracks according to the playing order
3) DSDMerge: DSD tracks -> one big DSD track + cue sheet
4) Compress the merged DSD with Philips DST Encoder
5) Philips SuperAuthor: SACD-R authoring with using the cue sheet for
track point information

Is there any way to reverse this process? (Get individual tracks
given one big DSD and a CUE)

[gfv]

Thanks for replies so far.

I have now managed to extract DSD files with Scarletbook, from an ISO
file.
I have not found anything like DSDMerge.
I have not tried Philips DST Encoder and SuperAuthor.

Any further help would still be appreciated.

[grill]

PM sent regarding dsdmerge.

[grill]

I'm not aware of a simple way of the reverse process for mch audio.
Afaik the author of this tool is Russian so if you have a "Russian
connection" then try to find out there. Afaik stereo DSD can be split
with AudioGate but I'm not sure if that process is simple or not.

[gfv]

It seems the last step (using SuperAuthor) is the difficult one. When
trying to create an image, I get "Error : Cannot create DTCP file".

Any ideas?

[adamic]

I am getting the same error.   

[realafrica]

I don't author SACD, but I remember discussion about this last step difficulty being discussed about a year ago.
It seems the authoring program can only author/encode one file at a time(?) so it is a problem with individual tracks. I believe the solution is something like, author as one single file, with a cue sheet to give you the track points. I hope this points you in the right direction.

Anyone know a nonwindows way to stream SACDs like you can do with JRiver and Foobar?  I'd like to do this on my Mac.  Is that because the core audio can't do RAW anymore and the newer OSes are all PCM?

I'm not sure about the locked in world of Apple but can you use XMBC on a Mac?
It's non-windows and can stream SACD-R, from the reports I've read.

[August Bleed]

Nice.  The only thing with XBMC is that on the mac side it is not bit perfect...it used to resample everything to 48.  I'm not sure if that would affect the streaming part or not...

[August Bleed]

Amazon?

Just curious, what does 'DST' stand for here?

Never mind, found it on the web

 

 .DST  = Direct Stream Transfer

 

alternately, an embroidery file ;>

[Alex]

Found it... where?  I've been also looking for it for ages.

"It" is the meaning of the initials 'dst'.  Nothing more.

Hi everyone  !
You can convert your files in multichannel Flacs one by one ___
Using AudioMuxer/Tools/Audio conversion/Mono wavs   __you will have 6 mono channels for each of the Sacd songs(same Bit Resolutions and Sample rates...)
After that you can use one of the methods below (you will have and hear very interesting(profi) sound experiences...!)
___

Remux the mono channels you already saved , together in new audio formats : dolby digital_ac3 /dvd,dts (cpt)/dvd , dts ES Discrete/Matrix ,DtsHd Master audio,High Res ,mlp etc...From my long experience working /testing Audio for many times and a lot of albums already finished , i reccomend you Remuxing your songs in Ac3,Dts EsMatrix and Dts HdMA all together for all the songs , recording the songs on a Dvd R disc playable on a BluRay player and the most Hd Media players(ISO disc)...
So you will have BluRay audio(and video if you want!) burning your albums/music on a Simple DvdR...
__To remux DDigital 5.1 i recc.  Minnetonka Surcode for DDig., Sonic Foundry or Wav to Ac3 Encoder...to remux simple dts(48khz)/dvd - Surcode for dtsDvd...to remux DtsEs,DtsHdMa, Dts High Res.5.1 to 7.1 etc - DTS Master Audio Suite 2.60...to remux MLP (for DvdAudio) __ use Min.Surcode for Mlp...
__And now...using Audio Muxer soft put first your ac3 songs all at a time (same bit res.and sample rate !!!)>>>select for each one a foto(google/name of pop group/pictures...better a good resolution___Add also a Thumbnail)___and mux all (you can also one by one...) ?to a mkv file(picture res.to hd -720p...btw)
__After muxig the song/s you will have an audio/video mkv file with d.dig. 6ch. sound...
Repeat the operation (remux) all your songs (leave this time default background on Audio Muxer0...
You will have , depending on how many format sounds you want to have on your disc (Dolby Digital_ac3 is anyway Mandatory__to make the disc playable on BluRay Players...) at the end 2 or 3 mkv files (with ac3 ,dts es and dtsHd etc....).
__Now , using tsmuxer soft , drag and drop your mkv s in to the window of the app._select BluRay(for BD discs) and AVCHD (for Dvds)_the audio quality will be the same... (you will have already chapters)...Important : you must to untick the h264 parts of the second and third mkvs_keep only the h264 video of the mkv file with foto backgrounds...  Start muxing !!!
___You will have now two folders  : BDMV and CERTIFICATE _ a nice BluRay structure disc ready to be burned ( i use imgburn / udf 2.5 and always Dvds...I play them on a Samsung BD player or an eGreat  hd media player...
I use also the method to convert all my prefered (stero albums or songs ) to 5.1 or 7.1 hd surr.sound ...(sometimes i combine audio with some video(bonus ,can be 3d also...)
Results are great  ( i use Adobe Audition or WavLab to create 6 or 8 monos from a normal stereo song...
Sound is magnificent !!! (If you work hard on the mono personalised chanels _results are (can be), better then originaly studio surround discs !)...
It is another methot to obtain a BDAudio disc (on a normal DvdR...) with veri nice authoring motion menus and playlists (BRay and Avchd format discs...) !
Thanks and Good Luck my friends !

[Costi Paul]

Sorry guys !!!
I forgot to specify : convert sacd files to multichannel flacs in Foobar 2k(Lossless , same bit res.and Sample rates...) !

Why would you convert SACD to PCM?  Almost every SACD out there has a high res PCM equivalent either on HDtracks or some other source.  You are taking a file likely an analog PCM tape master and letting it be converted to DSD only to convert it back to PCM.  I can see no benefit to doing so.  Can someone enlighten me a bit?  Here's a good question.  I have a 24/44 of norah jones latest album from HDtracks.  I have the SACD which was mastered from analog tape transfer of said master copy.  Now if I choose to convert BACK to PCM the most common lowest bit rate for that kind of file transformation is 24/88.2.  If you have a higher end SACD player the PCM might come out as 24/176.  So my question is what do I have if I convert the sacd to PCM?  An upsampled mess??  I mean the real master is 24/44...so the lowest conversion rate that approaches transparency is actually higher than the original master.  If anyone can help me to make some sense of this please do.  The SACD is clearly the best of all the copies I have and removes all the harshness and offending digititus that plagues even the master.  So again, when you take that SACD to PCM at even the lowest sampling rates you end up with a bigger bucket than the original master.  Please explain.

[August Bleed]

Oh didn't want to mean that in a demeaning way if it came across like that.  I was just curious as to why one would do that when most of the same stuff is available in some form of PCM that was converted by professional engineers.  It would seem if that possibility exists that would be the superior way to go sound quality wise.

[Robert Coogan]

One reason could be so you can create your own DVD-A.

 

Personally I find the discs play better on my universal player than burned SACD-R from ISO.

 

I only have a cheap player though which may be the reason.

 

Additionally it means I can read the DVD-A on my PC, which I cannot do on burned SACD-R (even though it was once a DVD-R).

 

Also you are limited by the size of the DVD-R rather than the existing SACD-R ISO using this method.

 

Many SACD albums are very short, an example being  Love Over Gold which is just under 41 minutes.

 

Authoring a DVD-A allows you to decide the content to go onto the DVD.

An example being a Beatles 24/44 album compilation in DVD-A format which I have a copy of.

 

I have previously used Foobar and Saracon to convert from SACD format to PCM and have not found any severe sound degradation arising from the conversion.

 

Purists may baulk at my departure from DSD but I am quite satisfied with this process on the couple of occasions I have converted to PCM/DVD-A.

Ah I forgot there are a few gems out there not in PCM, love over gold being one afaik along with the rest of the dire straights catalog save one.  If anyone can clear up my understanding of norah jones question I'd be grateful.  That one really stumped my brain.

[August Bleed]

Oh I don't baulk at PCM...I just tend to think if it was done as analog tape sacd seems to work really well and should stay that way (as should native DSD recorded music) and music recorded as PCM should probably stay that way. The one weirdness I've encountered is the Norah Jones thing with her last 2 albums and not quite getting the SACD transfer being alot bigger than what it started out as!
