@Brian: I clearly hear a difference for certain sounds.
I clearly do not hear a difference.

In my opinion, a lot of this has to do with two things:

1) Settings - Too closely-linked Band 1 and 2 in AGC, multiband really in need of overhaul (this is my FASTEST downspeed now: Decay speed - Band -1=0.000084083)

2) Power of suggestion - Someone says that something is better (or worse), and that influences opinion. My opinion is that there has been no meaningful change, either better or worse, thus making this venture have no Return On Investment.

Finally, the rub:

If these changes are something that you're determined to keep, then starting with BETA003, the CPU load on my system has increased by 50%. That is the delta - task manager reporting went from 40-45 to 60-70. Odds are that if you check with others with low-end AMD dual core and the early laptop versions of Core/Core2, they'll report similar increases.

The ability to toggle these new functions off, similar to the asymmetric bass, would be welcomed...

Ow, that doesn't make any sense. There could be an increase in 005 and 006 due to a changed default setting (not sure yet if that change is really needed), but that change wasn't in 003 yet. I'll check what's wrong.

Except for this, I have one more bug to fix for BS412 and then I'll quickly move on to the GUI redesign etc.

Well, 003 caused the bulk of the increase. There was indeed a little bit more of an increase later than that, but the bulk of it (> 90% of the increase) came with 003.

Also, here's you a copy of what is essentially my "Purity Control V2" preset. Feel free to test it with these changes and see if you really hear a difference between 6.30 and 6.31. At most, and this is really stretching it, I might be able to hear a very, very slight additional bass presence. Certainly not enough of a difference to warrant a 50% load penalty though.

Word of warning on the preset: The changes to the down speeds were done manually, not through the GUI, so changing them through the GUI will cause large changes to the preset's sound. Despite looking like they're all at zero, the first 4 bands and the very last band are above zero.

Erlier I posted two samples (thing about voice distortions caused by ..) I can again post two samples, processed in current beta and 6.30.
Will you comment it if i post it, since you did't say nothing about that two samples, but lot of other words?

I know what's causing the higher CPU load - there was some code that I wrote quickly to test this new bass clipping behavior, but I need to optimize it. :cry: - I'll make a fix later.

Btw: The fact that this costs so much extra CPU power might indicate some other problem. Not sure what though. It's a stupid piece of code, but it doesn't do anything difficult and it doesn't use much memory... (Basically, I calculate an RMS volume 100 times. Compared to other things that I do in the different filters this really should not use much processing power).

As I previously indicated, I think a large contributing factor are settings. Your settings are centered around the same AGC linking as has existed for the past year or more, which has Band 1 tied super-tightly to Band 2, so much so in fact that Band 2 is either almost-never or actually never pushed higher than Band 1.

If you want to post something processed, feel free, but also include the entire raw file that you use so that the processing can be done independently of your specific settings to see if the issue, real or perceived, is still there if processed with different settings.

Yeah, I didn't notice a memory usage increase, just the CPU load. Of course, the memory being used might be CPU cache, which I don't have something that can trace the CPU cache usage...

So Brian, do I understang right, there is settings that i can re-adjust and kill voice-distortion?

Neither Hans, nor I, heard the "voice distortion" that you did, which turned into the asymmetric bass lowering.

These are very, very, very low benefit items, meaning the time spent frantically chasing primarily your specific hearing, is not being spent on things that can be of benefit to more people other than the ~ 1% of users that have hearing like you do.

Feel free to post the samples, including the complete unprocessed file, not just a snippet, to prove your case and/or prove me wrong.

ok, since "now i know" you don't hear it, i will post you this new problem with bass.

http://www66.zippyshare.com/v/50587039/file.html

File contain 3 parts:
1. Original sample
2. ST 6.30 Standalone
3. ST 6.31 beta6 Standalone
- preset

Used only Loudness at max quality with only "Allow clip bass bellow" at -6. I assume that at many points "sensitivity" will alone bring that settings anyway to that point, so it must work good with settings like that.

tip: if you clearly want to hear difference between 2 and 3, put bass on your amlifier all the way down. or use any EQ to achive same.
