Stereo Tool

I've added this to the TODO list, will check it soon.

Thanks for reporting it!

Bojcha reported (in a PM) an issue with the non-phase linear high pass filter which is present since BETA080 (BETA079 was still ok), this one might be related to this DC offset issue. In BETA080 I made some changes to the 'processing window' shape which removed (or at least greatly reduced) the chopper-like sound, but it replaced that sound by a very low frequency tone. At the time (actually until right now) I didn't realize that a low frequency tone - which you cannot hear so until now I thought it was fine - is actually a DC offset.

I'll look into it further tomorrow. But I'm starting to get pretty sure that BETA080 must be the version where it started to go wrong.


*** EDIT ***: No, it's not BETA080 where I made that change. Looking now where I did.

*** EDIT #2 ***: The change was DEFINITELY present in BETA083. Now I really don't understand what's causing Bojcha's issue in 080 anymore...


Anyway, this probably means that the DC issue is present since either BETA082 or BETA083. I'll look into it tomorrow evening.

Can you also explain the big difference between 28 and 30 ?

Not really - given the changes that doesn't make much sense (you're not using non-phase linear highpass filtering, right?)

No, i was using non-phase linear highpass filtering order 6.

HPF: This problem is from beta 80. Did not checked all betas but beta79=ok and beta80=not ok

I can record it (?) But i already sent you track where this is so noticable.

Ok, so far I've only looked at the changes - and this one is not reported anywhere but it's marked green from BETA083. Anyway some bad things are happening with that HPF - and indeed only when I enable it. I didn't hear what you described but I did see and hear a bunch of other things. I'll check tomorrow if those other things also started in BETA080 - if so it's the same issue and fixing either will fix both.

I have NEWS about HPF... Stay tuned ! this is crazy !

Few minutes ago i tryed to replicate what i sent to Hans as a problem. And i could not replicate it.
Only Never phase-linear HPF ON.
Then i loaded some web preset form file and bug is again there!
Next was strange! I presed RESET again, and turned on never phase-linear HPF ON only.
And BUG was there!!

Here's result.

used ST Standalone beta104. Played from winamp with VAC. 48kHz - Normal output

Hm, that might explain why I didn't hear anything! Will check you recording ASAP.


News here too: The change that I suspect of causing the increased DC content was in BETA082. So basically I expect that BETA081 has a much lower DC content than BETA082. It's getting way too late here now, so I'll continue with this tomorrow.

Hm? That's ONLY HPF on?! So the volume drops about by half and the punch is gone? Or should I ignore the volume etc?
