Stereo Tool

De-Clpper Dispay settings not saved too. (i preserve to keep only Input)

1 - Hm, I thought that was fixed - will check
2 - You mean the maximum slider I suppose? So 200% -> 170%?

Yes

Hm, makes sense. If there are NO low frequencies, values above 100% are all equal. If there are lots of low frequencies, a higher value for this slider means that you get more highs, but of course that also means that you get very loud highs + very loud lows. And that causes issues. So a slightly lower maximum value should help, and should have very little impact on the highs themselves (and, again, only in the situation where they would have a bigger impact on the low/mids).

The only situation that is not really solved this way is when the highs are very 'dense', which is the case among others with xylophones etc. Their RMS level and hence impact on the low/mids may already be high even if their peak level is low, even below 100%.

This is only occures if pre-emphasis is used (FM 50 or 75us). so proper composite clipper should fix this in better way i think.

That's what I thought too, but Leif said that that does not help.

Anyway, I think I know now how to really fix it, but I'll do that after the IBC - it will take some effort and I have hardly slept the last few nights.


I'll fix most of the other reported issues tonight, and upload some newer tracks to the perfect declipper site.

hmm..
Why then Omnia.9's HD (L/R) output have less highs then composite output. I think i heard like that.
On composite output highs are like embedded.

Am no Hans :
i`m talkin about the speeds not the levels . For the levels i know but what is the connection about the up and down speed . I think this is just the speed of respond for the level ->higher is fast , lower is low respond ...Don`t know it`s not normal .
Think that if we have separate speeds set for the bands , they have to be adjusted separately , not only one of them to affect to all bands ?!

From reading previous posts, I get the impression that most of you are feeding files into Stereo Tool, rather than real-time audio. The talk of switching pre-emphasis in from time to time makes me wonder how many of you use the FM part of the software.

While I don't profess to be an expert, even after 35 years around this stuff, everything I've worked with holds that composite clipping is a questionable option, embraced by some, but not all, and only for that last bit of competitive edge... certainly not to fix anything that comes before it. The software and surrounding hardware should be capable of handling any spikes without relying on composite clipping in any way.

... which Stereo Tool does pretty well, by the way.

There is more room for the highs - that is true. But according to Leif it doesn't help to reduce volume drops in the mid/lows caused by loud highs.

@rodeojack: That's 'traditional' composite clipping. We are talking about the Loudness filter being aware of the stereo/RDS signal that's added later on, so it can put some extra peaks in the gaps that those signals create.
