clicks right before start of new track from .ISO (SACD)

<< < (4/9) > >>

AGAWA:
JimH,
thank you for letting me know that you are on the case.
I will not judge where the fault is but I see that there is a problem.

SW player should behave similarly to HW player.
SACD player is a mix of HW and SW, most part is SW like for example JRiver.
SACD player does not convert ISO to DSF, so I do not accept argument - convert to ISO and you will be good.

Perhaps initial click (when starting to play first track) and proceeding starts are being muted so no clicks are heard form SACD player.
I expect the same form SW player.

Let me summarize : ( I am not taking popular opinions into consideration, want to stick to the facts rather then "somebody soewhere heard something)

1. Click are not OS dependent ( I would say OS and HW )
I ran two tests :
- Windows MC27, ordinary Windows audio, straight to headphones
- Macbook , Catalina, MC26, core audio straight to headphones
the same results: Bach  - cliks in both cases
Vivaldi - no clicks in both cases.

I wanted to exclude popular misconcept of DACs producing clicks, this misconcept is being applied to all scenarios and allows to disregard the problem. Yes, I know that clicks are produced by DACs when switching the audio standard, but this should not be extrapolated to all situations.
Problem here, contrary to SACD HW player, is that SACD player can internally control DAC, while SW player has less power to control external DAC. Mute is the cure.

I was surprised initially, when I found that one ISO gives clicks and another one does not. And I started my investigation, playing ISOs, FLACS, DSF converted from the same ISO.

I guess this is all.

Both PC and Mac produce the same results in MC. If this is a problem with both types of computers then MC should take it it into consideration and provide nice solution, like for example muting of audio in short transition period from one track to another. Similarly initial Click when DAC  is changing  standard could be eliminated at the same time.

Just my thinking,
thank you

ThierryNK:
Clicks come from sample rates changes in the DAC, depending on DAC and on how the tracks are separated on the ISO.

7 years ago it was the main reason for me to no longer use ISO but only DSF files, with also the reason of tagging that is not included in the file and lost when you change player, and also the heavy usage of DST lossless compression on multichannel ISO that is CPU intensive and lead to dropouts when you use Wifi.

AGAWA:
Thierry,
please read carefully before you comment.
There are no changes in standard for DAC between the tracks.
And how will you explain the fact that one album clicks and another not?
I want to dig deeper and find the fault rather than accept popular knowledge.
According to your explanation DSF should also click in some unknown situations.
SACD players do not produce clicks on the said albums and this should be the goal for the  software player
cheers

ThierryNK:
There are a lot of possible reasons of pops and clicks apart sampling change playing ISO. Silence cannot be represented in DSD. SACD are not mastered the same way depending on how this silence is represented (PCM, or not full silence DSD), a lot of SACD players do not decode DSD but convert it to PCM before DAC.

I understand very well that you expect JRiver to avoid clicks playing ISO.

But I understand also that it may not be a top level priority as people having the right Playstation to rip SACD (I have 2 of them) are able to rip SACD to separate tracks,  but so many people having SACD ISO have illegally downloaded them and do not know how to extract tracks from their ISO.

I know I am not really helping you. Sorry. I will not post anything more on this subject.

AGAWA:
nothing illegal;
I own close to thousand SACDs and I'm afraid that sooner or later I will not be able to play them. My player does not convert them to PCM. Good PCM is  also very good. I have to take decision if to backup my disks or find another solution.
It will be very difficult to match SQ of my player.

regards, all the best
