SACD Ripping using an Oppo or Pioneer? Yes, it's true!

i have mastered many an sacd and without compression, multichannel wouldn't fit much, typically that compression is over 2:1

I have a few stereo only discs, and they are not compressed.  Surround tracks are normally compressed (not sure if it's mandatory though).  One thing you can try is to convert a local ISO of the ripped disc to DSF on a PC .  If you see tens of MB/s, that disc is probably not compressed.

 

I see, and that would explain certain isolated fantastic results I've seen, for instance the new Axis: Bold as Love Analogue Productions SACD reissue extracted from ISO at 55 MB/s on my MacBook Air.

 

That makes more sense to me now as the disc does have both Stereo and Mono mixes of the tracks, but no multi-channel/surround. So that .dsf extraction did not involve decompression, and as such it flew at supersonic speed.

I'm about to try my first SACD extraction with that AP Axis: Bold As Love disc. Just waiting for delivery.  So you're saying that you didn't have any problems?

Well done - glad it worked on your RPi!

The RPi3 b+ didn't even break a sweat, low CPU and RAM usage, and it didn't really warm up to the touch much either:

 

Usually I get one of these nice icons on the top right corner of my monitor upon ripping a full 6ch SACD ♨️

Pretty incredible how well this runs on such a low powered and low priced Linux box

 

 

 

Indeed,  but another bonus or treat is the self-reliance of the Raspberry Pi:

 

Thanks to AUTO MDI-X (no more crossover cable) and DHCP (offers IP to LAN devices), the RPi can rip from the SACD without any network infrastructure or additional devices (not even a monitor if the RPi has got an attached LCD module).

Since your tools have gone, where hardly any other disc ripper has gone before - the ARM world around a dwarf sun, the Android cluster shouldn't be that far away.

Should you ever choose to port sacd_extract(+GUI) to APK, do consider us for beta testing ?

The following manual is inclined to concur with your opinion ?

 

 

 

 

 

 

my two cents on the topic:

 

If you decompress a DST64 6channel file to DSD, a decent sw player (e.g. foobar2000) shows a constant bitrate (CBR) of 16934 kb/s.

Just like LPCM this is very inefficient, as each channel gets the same bitrate assigned regardless if there is any "sound action" in it or not.

 

The most common Digital Versatile Disc formats offer a maximum bitrate of 9800 kb/s (for audio this is only achievable via the DVD-Audio format).

This was officially surpassed by the shortlived 3X DVD format (basically a dwarved version of HD DVD featuring red laser and regular DVD capacities).

 

 

In order to fit the 16934 sound material into those 9800 you need an efficient but yet lossless compressor, which naturally has to use a variable bitrate (VBR). My guess is that the DST format solves this challenge rather nicely.

 

At last do rip a 6ch SACD without decompressing the tracks and you end up with multichannel DST files (.dff) which hardly exceed 7500 kb/s.

 

At some point it was even planned (version 1.3a?) to transmit DST over HDMI (sort of a SACD bitstream output mode).

 

 

 

Last but not least, is CA SMD = doom9 SMD ?

No problems at all, in this post a few pages back I showed the result ripping it straight to .dsf, 3.05MB/s is fast.

 

The post above that you quoted however was a different test on that same disc in which the SACD is first ripped to a full archival ISO, and then the .dsf tracks are extracted from that. That's where the supersonic 55 MB/s speed was reached.

A simple set of instructions for Mac users:

1. Use Oppo Remote iOS app (or whatever method you like) to find your player’s IP address on your network.
2. Insert USB stick into any of the Oppo’s USB ports. Disk drawer will open almost immediately.
3. Press Execute button. Ripping will start in about 10 seconds and progress bar will show.

Thank you all for the great input. Trying this for the first time. regarding the three items above:
My Oppo 105d is connected to my wireless network. I know the IP but how do I know the port?
When I inserted the USB stick, the door did not open.
When I pressed execute I got "Failed to connect Libsacdread:Can't open 192.168.0.9 :2"
that "2" at the end was one attempt at guessing the port. I've tried other numbers I thought might be the port, but obviously I need help with this.

My mac, running yosemite, does not see the Oppo but I read that in many of the comments. I am using an airport extreme on wireless. Though I tried hooking my laptop (2013 Macbook pro) via ethernet directly to the oppo, but I assume that doesn't really network that way. I'm guessing my problem is most likely not having the port?

any help is appreciated and I do apologize if I missed a solution. 

thanks

I'm guessing I've got something else I'm missing since I did try that first. 
Though I will try it again.

you need a crossover network cable for this..everyone should have at least one

Many of the Ethernet transceivers today support Auto MDI/MDI-X which allows direct connection with a normal cable.  For example my old mac mini 2012 can talk to BDP-S5100 directly with a normal cable.

Just curious can one rip Blu-Ray audio using the Oppo Method?

No.  Ripping Bluray’s can be done pretty easily with a Blu-ray drive connected to a PC and using software such as MakeMKV, AnyDvd HD, etc.  There’s no point in anyone putting any effort into figuring out if it can be done and how with these players that can be used to rip SACDs; it would just be a waste of time since there’s already an easy way to do it.

I remember those. Been years.
I've gone back to wireless. We just upgraded our wireless to a Linksys Velop.
Updated the ip address in the software after changing networks.
Verified the correct files were on the thumb drive.
Drive does now open on power up.
Still get the can't connect screen shown in the attached photo

Agree 100% - especially since USB Blu-Ray capable drives are not expensive.

Some updates to my being unable to have success. 
We now have a linksys Velop wireless system. My signal is way better.
I have only had the Oppo door open automatically once. Other times I had to turn it on, with the thumb drive already inserted, and then the door did a very quick open close thing, with or without a disc in.
Finally when I clicked EXECUTE in the Sonore software I didn't get an error. However, I didn't get anything showing in the Sonore software screen and it doesn't appear that the USB stick is doing anything.

one thing to note, on the Oppo main screen the icon that just says network, if I select that option is shows 0/0. If I select it it spins for a while but nothing shows up. But I am on my network as we were able to use the netflix app.

 

I've never been much for networking my computers. Is it possible some sharing or other networking item is not set correctly on my Mac?

I have pushed this small change to github:  Now sacd_extract indicates whenever it is doing DST decompression like this (note "(d)"):

I would suggest confirming that IP address belongs to the OPPO not something else in your LAN (you should be able to do this in OPPO's menu) and then try pinging the IP address.  If the IP address belongs to the player and there is echo,  then the server program is probably not running properly on the player side.

Thank you for the suggestion. I was wondering if Oppo is showing me the correct IP address in its network menu page. I've been using Macs since the late 1980s but sharing and servers are something I have never really done. I'm not really sure how I ping the IP address.
I have networked back up drives attached to my router and accessed my other computer from my newer one. But that is about all. Time to do some learning.

Well you could be right, since "lazy" Android smartphone users will probably only do stereo / individual track ripping, from their armchair after listening to the SACD in the living room.

The whole potential (full or 6ch rips) would only be unlocked by the small minority of premium tablet users (with HDMI port) and set-top-box owners (e.g. nVIDIA Shield TV).

Here is the ping test results, I assume this means they are communicating.
 

--- 192.168.1.77 ping statistics ---

10 packets transmitted, 10 packets received, 0.0% packet loss

round-trip min/avg/max/stddev = 4.974/13.237/49.867/13.212 ms

 

If so should I perhaps try a different thumb drive with the script on it? I have verified my drive is Fat32 and the script contents are there in the correctly named folder.
