Thanks for your measurement! So the phase linear version is perfect?! And, how is the never phase linear version with the 1st checkbox on and the 2nd off? That should be close to always phase linear.

About the small difference for checkboxes on and off for phase linear: Are you using Bass Boost? (My guess: No).
Phase linear version is better. At least with this song that i'm testing with.

I tried with reduce artifacts off and never phase linear = 75.3 kHz

I am using Bass Boost.

When i test this with the pira analyzer i get every time another max deviation. So i have to play the file many times to find the real max value. So the difference can be slightly greater for checkboxes on or off with phase linear.

- Strict bass clipping is back! No further changes.
Is this check box linked to the Strictness slider? CPU load increased significantly at +4 (where I had adjusted up to) with the strict option checked, but is back to only a minor increase with the slider at 0. Might still check for optimizations though.
It is, but it should not have this much effect. (at quality 0 I perform 6 clipping steps. At +4 that's 8. Not a big difference.)
Could be one of those just-over-the-limit memory things. I'm just leaving it at 0 for now, or maybe +2 (which I assume is 7 steps), and maybe the utilization will improve over time...

No, because I just repeat the same step a few times in a row. Using the same blocks of memory each time. And I do nothing in between.

Are you sure that it's not one of those Task Manager jumps? I could probably just as well limit the bass clipping at 6 steps, but it _really_ should not make much of a difference (like at most 2-3% of the total clipping CPU load - that's what I'm measuring here).

I'm as unsure of it as I was unsure of it the time I brought this up and you added the "Take some shortcuts (CPU)"... ;)

...and the time after that when I brought something else up and you made an optimzation (I can't specifically remember what that one was, and I don't have time to look right now).

Until you own a CPU with 1MB cache (per core) and test on that limitation, and perhaps more significantly, an AMD, we're going to have these "you sure it ain't Task Manager" situations... :sigh:

I know... But this time it really doesn't make sense. What I did is add a loop like this:

FOR i FROM 0 UPTO 5
DO something;

Now you say that at '5' (6 steps) it takes almost no time, but at '7' (8 steps) it takes a lot of time. That really doesn't make any sense. 'something' doesn't suddenly use more memory if the number of repeats is increased, and the 'strict bass clipping' CPU load should rise by 8/6th. -> 25%. But since you say that at 6 steps it's not much higher than without strict bass clipping, I don't get it anymore...


I'll create a version where the number of steps is limited to 6, then we can at least see if it's the bass clipping or the total clipping filter that responds to the increase. Will post something later today.

Odd... http://www29.zippyshare.com/view.jsp?lo ... y=97565454
De-Clipper > at about 02.46.

Jesse said that 'Distance to vail' is better at about 77%, i am geting better at 94%.

And again after all, i still think that Phase-linear HPF should be before AGC.

The button that connects bands 1 & 2 disappeared in my install, beta 114. Was this intentional?

Thanks!

here is mine setting:
- nice, for all types: 2.20 / 1.25 / 0.99
- hardstereo boost: 2.20 / 2.00 / 0.99 / 'protect Against' ON

I did notice a better restoration of HF detail, but that wasn't completely the problem I was having with the declipper not declipping clearly clipped peaks. I do notice that in the Omnia.9 it's working almost flawlessly, and all it has is a "less-more" slider. So it's possible that the default settings had been updated and I hadn't learned of it.

Coincidentally, I just checked my last preset and I have that set at 90%. So I'm not sure what I was doing with 77% or it somehow didn't translate from my preset file to the latest beta.

Brings up a good point, maybe a good feature for Stereo Tool would be a "Default" button on each area, to reset everything to the optimal settings in that area (loudness, declipper, etc).
