Stereo Tool

Woops. Ok... So in version 6.10, I increased the Punch start value further and further until I heard no more artifacts from it. Well, turns out that that was because the level was higher than 99% of the audio that comes in .

Instead I'll now make a version where the amount of artifacts is predicted (based on the amount of bass), and which also takes into account whether these artifacts are masked by other sounds (higher frequencies). For higher latency settings, this should behave very close to 6.00 (except when there are no high frequencies present, in which case Punch is useless anyway); for lower latency settings the behavior gets closer to that of 6.10.

ok we'll see..
btw.. bug for MB, other then default freq. when used, bands not loaded always. (some trigger needed to make freq bands working as should)
I am asking, because i have one interesting preset, where bands are slightly changed.

Loudness Punch: Now similar to version 6.00, except when loud bass sounds are present (which cause artifacts) and there are no highs that can mask them.
- Just replaced BETA620-009 by a new version where loading presets with changed multiband frequencies should work.

TODO:
- Fix loading changed multiband frequencies
- Add buffer and filter for SCA output 1 day (SCA1 ok, SCA2 not yet)
- Finish AGC improvement ? - make mono value configurable (replace checkbox by slider) 1 hour --> NO, not needed - anything else needed?
- Fix Punch making it dynamic will cost 1 day
- Check what to do with new filters (such as bass AGC) - keep them, remove them, change them?
- 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.......
- Change version number 1 hour
- Release 1 hour

Why now

I don't criticize that this is fixed now.
I am only surprised, because it seems as if this problem was unknown.
I thought that this problem was known (by Hans) since phoenix' and my posts in the other topic.

It was known since those posts, I just forgot to put them on my todo list...

I must ask agan, all, Does Highpass Filter should be BEFORE or AFTER MB ?

My answer:
- Non phase linear: Before. Because I can only do it before or after ALL the processing, so there's no other choice...
- Phase linear: After. Because otherwise the few dB's that the bass is reduced will immediately be restored by Multiband. On top of that, filtering artifacts will be increased by Multiband.

@ highpass: OK, that's case now and logical, but i just checked "others" and on all is 'before' mb.

@ Punch: it's good (better).

1 - I placed it at the start as well, but due to the artifacts and not very effective filtering I had to move it forward in the chain. First step would make sense (and not phase linear also works that way).

2. Great! Should be equal to 6.00 behavior for > 90% of the sounds - at maximum latency.

@ All (especially Hans and Bojcha)

Please, I need some feedback
