clicks right before start of new track from .ISO (SACD)
AGAWA:
Now - my last post in this conversation.
My very important question to all of you who are convinced that need to teach me basics:
Is .ISO file that is produced by SACD Extract (old and fork) an exact copy of .ISO on the disc?
Please remember that this is simple file transfer from the SACD disc player to computer.
SACD players (spinners) play from .ISO structure and do cope with all kind of weird things buried in .ISO.
Perhaps they just mute transitions and hence play without any clicks.
Having tested several .ISO files from various periods of SACD discs manufacturing times I intend to think that with introduction of MCH discs there were improvements to MCH side of things. 2ch left as it was.
Will do more testing as I progress with backup of my collection.
Fork SACD Extract is just nice workaround and it produces DSF that play without clicks, but I would like to see problem caught at source , and not requiring workarounds.
Implementation of MUTE of transitions is an easy task and could be applied to all formats. But I also understand that this is a matter of priorities .
MUTE would make the solution elegant and this is what we expect from software.
There is some interesting reading (you know it perhaps):

As I said , this is my last post in this matter, unless you would like to proceed further.
AGAWA:
Older SACDs have ver. 1.01
Newer SACDs have ver. 1.20 for both 2ch and MCH areas.
Tested another 1.20 SACD ISO - no clicks.
AGAWA:
I see no further interest to fix this problem.
I have read that some makers of MCH DAC , when reviewer discovered clicks on switching, made a correction to avoid any clicking.
ISO playback is supported by MC, with advice - better convert to DSF and it will be clickless.
AGAWA:
Is there an option in MC to extract DSF files on the fly from ISO container?
Extract track after track and play them as DSF extracted on the fly from ISO?
This process would buffer the full track and have tracks ready for play one after another.
Awesome Donkey:
No there isn't. MC can convert them, but that conversion goes through a PCM stage in the middle so it's a lossy conversion. To do this correctly you'd have to use one of the forks of sacd_extract from the command line (or GUI if you can find a frontend) to extract DSF files from a SACD ISO.
