Lol, man, I just discovered that I completely forgot to buy eggs. I don't even have a single one here! :evil:

But it is indeed hot and I am enjoying the sun - just walked inside to cool off a bit...

This is one of the main reasons (besides the other reason to have someone that must drive you home when you are drunk) why most men finally get convinced that it is better to marry.

To have a wife that takes care of the eggs !

BETA620-030:
- Declipper: Added settings to reduce (or increase, better quality!) CPU usage
- Declipper: Optimized code for lower CPU usage
- Non-phase linear highpass filter and low latency phase rotation can now be used when declipping is on.


Notes from previous BETA (about declipper):
Quote:
Note that declipping uses a lot of CPU processing power (I'll make that configurable later).

The filter can be switched on or off at the right of the input level slider.

The 'maximum peak restore' slider does not work yet (dunny why, will check).

IMPORTANT: Set the 'clipping detection' level low enough such that ALL the clipped samples are recognized as being clipped (for a CD that's easy, 32767 should suffice, but for an MP3 you'll need to set it a bit - even upto 10%! - lower).

Hint: You can see that the declipping filter is working by comparing the input and output levels with NO other processing enabled.

Samples that are incorrectly seen as not-clipped (level set too high) can have a big effect on the audio.
Samples that are incorrectly seen as clipped (lever set too low) make things harder because basically Stereo Tool must treat them as if they are clipped at the selected level. So basically you add extra clipping before removing it.

Later I'll add some code for dynamic clipping detection. (Something with a histogram I guess).
Winamp DSP plugin: http://www.stereotool.com/download/dsp_ ... 20-030.exe

VST version: http://www.stereotool.com/download/vst_ ... 20-030.dll NOT AVAILABLE
VST version (No SSE2): http://www.stereotool.com/download/vst_ ... 20-030.dll NOT AVAILABLE

TODO:
- Fix loading changed multiband frequencies
- Add buffer and filter for SCA output (SCA1 ok, SCA2 ok)
- Finish AGC improvement - make mono value configurable (replace checkbox by slider) 1 hour --> NO, not needed - anything else needed? -> NO
- Fix Punch
- Check what to do with new filters (such as bass AGC) - keep them, remove them, change them? --> KEEP
- Save new BASS_AGC setting in VST mode
- Loudness: Annoying cracking sound in bass. Slightly present in 5.00, worse in 6.00, maybe even worse in 6.10. Only when bass is too loud. Much worse than in Final Limiter (at same input level!) - so this clearly indicates a bug. Most likely cause: The filter that was added to remove bass artifacts....... :shock: - No, it's the louder bass. But it can be fixed by changing some settings. Default settings updated, and behavior for 'not Very strict' improved. Also Deep bass boost and Very deep bass protection are enabled for latency 512 now.
- Finish declipping filter.
- Finish new de-essing filter (check what to do with the settings, remove at least some!)
- Add lowpass filter for stereo signal (will cause a lot of extra latency!) - it might be possible to avoid this latency using a Hilbert transform
- Update presets? (BASS_AGC etc.)
- Change version number 1 hour
- Release 1 hour

Great !
But BETA 30 ?
Where is BETA 29 ?
Lost in space ?

Or is this my guiltiness, because I confused everybody here (including Hans) with my multiple requests for a BETA 29 (same as 28 plus saving for dynamic boost options) ? :oops: :?:

Here is a new example with Dynamic Boost x1.50:
http://www38.zippyshare.com/v/77459428/file.html
The Kinks - You Really Got Me.
Two MP3 files in a ZIP.
One minute original from Disky CD Release 1996.
And one minute remastered with ST6.20b028 plus Dynamic Boost x1.50.

PS: I guess there was something wrong with earlier Beatles example (probably DyBoost not enabled !? - I will check it later).
But this should be correct (with DyBoost).

Please, give me feedback for this !

You do know that staying single is the best way to avoid getting fat, right?

A single man comes home, goes to his fridge, doesn't find what he wants and goes to bed.
A married man comes home, goes to bed, doesn't find what he wants and goes to his fridge...

It could be something similar to my joke about one of my versions of a preset. I skipped from one even number to another, so I put in as a FAQ about what happened to the other version and that it was "kinda odd"... :lol:

In stand alone version i can't set Tilt for peak detection and next slider. Is this supposed to be?
Will you also add auto clip level detection for this beta release?

Hi Eldoradofm,

I've been rewriting the code for better performance, but the tilt part fell off for the moment. It will be restored (actually I'd like it to be automatic instead of having to set it manually).


Note about BETA029: There was one on my pc.... I don't really remember what it is (I might have created it in Vegas to fix some issues). So that's why I continued with BETA030.
