Stereo Tool

Yes 4096 no SSB, i think it was with oversampled pre-clip and Als low freqs ON.

Latest beta rockin! lower cpu useage, and you guys build really good presets!! Hans you are amazing!!

:)

CPU load will go up a bit in the next beta (I changed the default Strictness setting for composite clipping from 12 to 15). Except for that I expect that the next version will be the new release!

while still maintaining the same value of "strictness" that the current version or just because the default will be more valuable?

Just the default changes. If you select 12 again you'll get the same CPU load as with (default) value in the previous beta.

RELEASE CANDIDATE
Stand alone: http://www.stereotool.com/download/ster ... 20-016.exe
Winamp DSP: http://www.stereotool.com/download/dsp_ ... 20-016.exe
VST: http://www.stereotool.com/download/vst_ ... 20-016.dll

IMPORTANT: To get a good sound from the composite clipper:
1. Enable it It's an option under Advanced Clipper
You need a license update to use this! Otherwise the 'unregistered options in use' thingy will pop up, and you'll get messages through the music (every 4 hours).

TODO:
22. Release

DONE:
25. Add and update some more presets (Bojcha).
26. Make Hard Limit behavior for composite clipper less steep (causing less artifacts).
27. Increase default Composite clipping strictness to 15.
28. Fix Stokkemask clipper. --> Done, but has too much effect on highs and stereo separation. Needs to be calibrated, it's probably too strict now.

DONE IN PREVIOUS BETA'S:
1. Move or copy (same as Stokkemask filter) composite clipping and SSB settings to FM section.
3. Perform same performance optimizations in traditional clipper; remove 'Stronger clipping' slider once that's finished.
6. Replace DIV_PS by RCP_PS + MUL_PS in new clipper
4. Check bass and mid clipping issues reported by Bojcha.
5. Check clipping bug when clipping a 20 Hz bass tone and set bass clipping (in code) from traditional to MPX clipping. Why is the output level higher??
Ad. 4: Clipping is set to 'traditional' clipping for both bass and midbass. But levels are not adjusted to make room for the pilot and RDS signals. Also, potentially stereo bass will not be clipped optimally. However, if I want to use composite clipping for the (mid)bass as well, I need to fix a bug (currently multi-threading gives different output levels, I don't know yet why), and bass clipping strictness must be greatly increased, leading to a much higher CPU load - so this is probably not a very good idea. The simple solution is to adjust the clipping level to make room for the MPX signal. (Stereo pilot 9% + RDS 4.5% means that there's 13.5% headroom needed, so for default settings that means the clipping level must be multiplied by 86.5%.)
7. Check holes in center of bass -> might be better with new clipper --> Checked, little difference (some are better, some are worse).
11. Red output bars
12. SSB mode: Red output --> Not yet thoroughly tested, but should be fixed now. Added 0.01% headroom. Twice that for SSB mode. 1% for Hilbert mode (and that's still not enough - but you shouldn't use it anyway).
13. SSB mode: Check difference multicore/single core. --> Was pretty bad, now ok.
14. Fix behavior: When Composite Clipping enabled use normal clipping if FM or FM stereo coding is not enabled.
9. Update settings (default strictness values etc.) Jeroen Platenkamp's presets strictness can be lowered from 13 to 8 and it's still stricter than before
16. GUI crashes. This is new... Needs to be fixed.
17. "Performance: Not low freqs" and "Traditional bass/mids clipping" have a very similar effect, and I should probably remove one of them.
15. Maybe make separate Strictness slider for Composite??? And also Loudness?
18. Make sure Composite Clipping is not changed if you load a preset (part of FM settings)
19. Separate Composite Clipping settings into GUI modes (hide SSB in basic or simple mode etc.). Hide more from Loudness settings than from FM settings.
20. Update presets
21. Change version number
23. Add warning if Composite is not enabled with FM. Clarify text (few dB more headroom, especially for highs, more loudness).
24. Fix clipping display.

hello, first of all congratulate you on your work, I love the clarity of the new clipper, is excellent

I would like to know what you think of the dynamic adjustment for sound density attack/release .(http://omniaaudio.com/11)
Even not hear a omnia 11, but seems like a good idea.

Hans, in the preset GAP_Dominator_v0.3 you incorporated in the Simple Clipper Amplification value is wrong 62 instead of 100%. (if you generate a new release is a new version of the preset)
I think the other presets aggregates have the same problem.

That's in the Generic version of the preset! Under "Web radio" it's exactly the way you made it...

Testing latest beta, composite clipper on, extra composite 1.05x, strictness 15.

Tested with 15219 Hz tone that Bojcha did yesterday:

- Red output bars on / off.
- L+R part jumps in spectrum
