Author Topic: [Bug?] Crazy glitches when DoP playing Michael Jackson's Triller SACD iso  (Read 2180 times)

Most of my stereo SACD iso are being played perfectly well on MC23 in DoP mode.
But there is at least one that fails: Michael Jackson's Thriller.

The Billie Jean track is the most exemplifying.
It frequenlty interrupts with some hiccups glitches and fade-in resuming in the beggining of the track.
I have found that this SACD is one of a few with too hight peak levels or something.
But the same ISO plays flawlessly when mounted to hardware player Pioneer BDP-450, and play well in MC23 if i disable DSD bitstreaming.
And i'm sure the software player should cope with it not worse.

The DAC i use is Light Harmonics GeekOut 450 (USB) with LHlabs (Thesycon) ASIO drivers.
I tested in on two rigs: Windows 7 Pro64 with MC22 32, and Windows 10 Pro64 with MC23 32, and with different driver versions both ASIO/WASAPI - the same glitches in all configs.

I have this album, which I took the ISO to then used sacd_extract to extract the 2.0 tracks as split DFF files (then I took the additional step of using a Mac and the dff2dsf app to repackage, without re-encoding, the DFF files to DSF files so I can have metadata) and the album plays fine when DSD bitstreaming, including Billie Jean. I also checked with the source ISO file (and the DFF split files I still have) and it still plays fine, again, including Billie Jean. Even though it doesn't do it with the Pioneer, I'd still check the source ISO.

Did you rip the SACD yourself? If so, you might try ripping it again and see if the result is the same.

Are you kidding? i should download sources and compile some tool and then manually remux the iso?  ;D ;D ;D

If hardware player plays given ISO flawlessly, but software one - not,
it means that there is a bug in software algorithms - either in MC (extraction from iso,gain/volume handling, DoP packaging) or in DAC driver.
I can upload the mentioned ISO file for testing/debugging.
And if i'll find someone to borow different DoP capable DAC from, then i'll rectify if it's DAC or MC flaw.

And nope. I don't have PS3 ripper.
So i just search and download other's rips.

It might help, besides, you don't need to compile sacd_extract from source when it's available precompiled with Windows binaries here: https://github.com/sacd-ripper/sacd-ripper/releases

Requires using of the command line, of course, but that's easy.

I'd try creating a 2.0 only ISO first by putting the Thriller ISO into the same directory where you have sacd_extract extracted into then cd into the folder using the command prompt.

This should create one for you;

Code: [Select]
sacd_extract -2 -i "PATHTOISOFILEHERE\Thriller.iso" -I Thriller_stereo.iso -c
I just tested it on my Thriller ISO, and the new stereo Thriller ISO works fine with no issues. From there you can adjust the options if you want to try split DSDIFF (DFF) files.

It seems to be well known issue:
(see http://forums.stevehoffman.tv/threads/michael-jackson-thriller-analog-or-digital-multitracks.87013/ and http://www.psaudio.com/forum/dsd-forum/clipping-dsd/):

"The SACD of Thriller was mastered with peak levels above the recommended maximum level contained in the Scarlet Book (a result of good DSD metering not being available at the time) so could sound 'hard' on a player that cannot cope with its large amplitude signal. On a player that converts DSD to PCM there is the potential for clipping depending on how the relative 0 dB levels are determined in the translation from DSD to PCM."

"the US version of MJ'Thriller on many players will clip and not sound so good. The japan SACD [still in print?] is the same mastering but was shifted so it conforms to the standards – a different mastering in effect some would say – and sounds noticeably better depending on transport."

"I still have Korg’s AudioGate 2.1 which was available for free via a twitter promotion back in the day. It still works great and allows to output DSD from DSD input.
So, I used the recommendations at this link to avoid clipping of the files. As can be clearly seen – Billie Jean is the worst, requiring a whopping 4.8db reduction to avoid clipping."

I've made this stereo iso, and it hase the same problem...
May be you have rip from japan transfer ?
