Stereo Phase

Hi,
i am trying the Audio Unit demo.
The "Stereo Phase" parameter seems to have no effect. Even when turned to 0°, while Fazortan is fed with a mono signal, it clearly produces stereo movement.
A bug, or user error?

Weird, after removing the AU from the track and instantiating it again, it works like expected.
But after a while the "Stereo Phase" knob again has no effect.
Is this some kind of demo restriction? Would surprise me, since all the other parameters still work like expected - just "Stereo Phase" stops working (before the 30 minutes timeout).

Hi.
Which host are You using? I tried the demo now with Logic mono track and everything is fine - Stereo phase has nothing to do with the input sound.

This was in Live 6.0.10.

Sure, I know. I just fed it with a mono sound (on a stereo track btw.) to confirm and make sure it's not a stereo movement from the source signal itself that I hear.

If You have a stereo track Fazortan should process L&R channel respectively. Please send me an Ableton project file - i think it's the shortest way to check what's going on. Insert one stereo track with mono signal and insert Fazortan - set it as You wish. Save it and send to
contact@d16.pl
Kind regards

Done. Quoted the thread title in the subject of the mail.

By the way, another thing I noticed when feeding Fazortan with a mono signal:
The more you turn the "offset" parameter of LFO1 towards "max", the more mono a signal becomes (in this case with "stereo phase" set to values other than 0°, even when set to 180°). At "max" it's completely mono.
Is that behaviour intended?

Total range of phaser frequencies are bewtween 0.0 and 1.0. When You set depth of both LFO's to max and then a lot of OFFSET then overal curve is close to 3.0 - so clipping to value 1.0 occurs. In other words each LFO Depth has range between 0.0-1.0 and so the OFFSET.
LFO1 Depth(max) + LFO2 Depth(max) + Offset(max) = 3.0
Now when both LFOses are clipped then for a while they have both value 1.0. In this situation there is no reason to hear different frequencies in left and rigth channel. Is it clear?

Hi,
i've tested Your attached project and everything was fine. Thanks for the sample - now i exactly know how it sounds. The only difference is that we have Live 7.0.3. Fazortan worked fine until reach 30 mins of demo processing. We'll check it deeper.
