All,

I am the most sorry to say, but I again found that the ever named "compiler bug" is still in there. By now I don't dare to tell anymore where it exactly exhibits, but at least I now found a normal frequency in the audio band. Well, sort of - 20KHz.

My Dirac Pulses (which are on another frequency outside of the audio band) were solved last time, but now I coincidentally ran into this frequency. And with this exact 20KHz as one of my test signals I assume there may be many more.

And so I can't advise other than switch Peak Extension On again because then it doesn't exhibit (what ? distortion).

And you know what (here comes a teasing) ?
I am a step further again on SQ but I started to hear some kind of nastyness. A strange sibilance in the highest frequencies. And now I think it can well have been this. I play with PE On right at this moment, and ... shivers !

What I did not try myself (say, fedup with it) is letting this loose on Windows 8. So, no no, don't reinstall W8 again. But when someone is around who has it readily available on a Dual Boot or something, please try this. It can well be that it solves a few things there ...

Sorry for this !

So for SQ Peak Extension should be switched on or off?

I'm still using W8 in my office. Switching Peak Extension to 'ON' has exactly the effect that you'd expect from previous PE experience. The edge is taken off the sound and it comes across as more balanced, and less annoying. It's actually quite nice. Unfortunately I don't have W7 on dual boot on this PC to compare, but I could live with this sound (in my office at least).

Could it be that W8 is actually more transparent than W7, and what we've been hearing are the side effects of compiler bug issues with PE='OFF'? Seems a long shot to me, but maybe worth investigating further. It's prompted me to sort W8 out on my main system again. I do have W7/W8 dual boot there, but for some reason, my W8 seems to have become corrupted - I think by physically disconnecting the HDD whilst in Min OS mode.

Will report back once I've had a chance to compare, but probably won't be for a while.

Hey Mani - that is interesting I will try it tonight. If it is possible to lose the "edge" in W8 that would solve two problems in one for me.

This is slightly embarrassing - I just checked and found that I have been listening to W8 and W7 with PE on without realising it. I have been concentrating on all other settings so much that I missed it. No problem though.

I believe the following two statements are correct.  Can you confirm?

This compiler error bug doesn't manifest:
  • 1)  if the interpolation slider is set to 1x.
  • 2)  if no interpolation method is selected. (bit perfect samples are repeated)

=====

What about if L or AI are selected?

Charlie,

Without hooking up the analyser and so by NOT 100% guarantee :

•1)  if the interpolation slider is set to 1x.
I don't think that will matter (problem still occurs).

•2)  if no interpolation method is selected. (bit perfect samples are repeated)

From what I last found, even that exhibits the problem, although this is not what I had in mind. I could also say : for my 20KHz test signal I tried to find one situation which worked, but I did not find any. Please notice though that with the NOS1 all combinations double because there's the "Is NOS1" mode and "normal" and this all can make a difference.

Quote
What about if L or AI are selected?

Same story, although I sure did not try Linear. AI is more difficult to test/compare because it only upsamples to 192KHz max.

There's just something messing up with the Volume and where -somehow- the base "factor" of 1.000000 does not turn out like that at all. Also, this is actually a known phenomenon and something like 1.000000 actualy is 1.000001 or something like that. And then for insiders : The maximum (think 16 bit domain) is 1 x 32767. And you know what ? 1.000001 x 32767 = more than 32767 and this means that it will become negative (-32767.032).
Now, everybody will say "come on, this is solvable !" and it is. For example by turning the standard 1.000000 into 1.001. But now the volume will not be "losless" anymore and when I sneaked that in as a solution a couple of versions back, people complained about SQ ...

Peter, another question about PE and HDCD...

Since 0.9z-8-2, I've been drawn more and more to HDCD recordings. I've said before that there's a 'sweetness' to them that I really like. I think my system is finally resolving enough to distinguish between good and bad ADCs used during recording/mastering. There's a lot of variability between the sound of various recordings of course, but HDCDs sound consistently good.

So what settings should be used? I've tried 3 different settings, with totally different results:

1. PE and HDCD on. Very laid back, smooth sound. Easy on the ear, but lacking a bit of sparkle.

2. PE off, HDCD on. Too bright and too forward. Slightly aggressive leading edges. (Might this be due to VC issues?)

3. PE on, HDCD off. The best sounding. Very smooth but with the sparkle intact. Maybe just a tad too 'holographic' sounding.

So, 3 is my favourite. But I'm worried that I'm missing out on the correct HDCD decoding.

Any thoughts?

Mani.

Mani,

The solution to this will be a very different, fresh and unexpected one. I will announce this in the Release Notes to 0.9z-8-3.
Prepared to be shocked. The most shocked ...

PS: And no, this is not about the "tweak" you already know about. Hahahaha.

Hi Mani,

Maybe irrelevant as we are about to be shocked  Shocked, but there is one combination you didn't mention which is both PE and HDCD 'OFF'. This is my personal favorite, as to my ears the sparkle is there without leaning to aggressive.

Cheers,

Hmmm... it's complicated...

Peter says we need PE 'on' in order for a truly lossless volume control. Certainly, with PE 'off' the sound is more lively and has more 'sparkle' - but is this the dreaded 'fake detail' that we can all get caught out by? Don't know.

As for HDCD, well it depends on how the Pacific Microsonics machine was set during the mastering. There are two HDCD processes; either, both or neither of which could have been engaged during the HDCD mastering. I'm not sure if the HDCD plugin that Peter uses (I'm assuming HDCD.exe) is intelligent enough to do the job of figuring out which of these three possibilities has been used. In any event, if either or both of the HDCD processes have been used, then HDCD should be 'on' in XX. Replaying these HDCD-encoded files without correct HDCD decoding just sounds wrong to me... all IMHO of course.

Prepared to be shocked. The most shocked ...

There are only a few things coming from you that would truly shock me:

1. AI is shown to be better Arc Prediction. (Nah, never.)
2. The VC is shown to be always lossy and you have started to advise people to use a preamp. Hmmm, could be possible. I still wonder if a totally transparent preamp (maybe passive) exists, in which case XX could be set permanently to the PCM1704s' ideal output level (-9dB?).
3. XX is no longer a true 'memory' player. Again, could be possible. Low SFSs are now working very well. Maybe the ideal is an SFS of zero?

Ha, this is fun. Anyone else with any ideas of how we are going to be "the most shocked"?

Mani.
