As said earlier, I have experimentally changed my ambient channels, once again.
No idea where this will lead to, as again perception is different. But is it better?

What have I done? I put the left and right ambient speaker out of phase from each other. As I am mixing in some summed content (representing the phantom material)
this still has left/right channel separation. However the phantom material will be out of phase, arriving from the lateral angles.

So far it's been fun to listen to. Still not sure if I'll keep it this way though. Time will tell.
Listening to ambient channels by themselves does give a distant feel to it. Different than having them both in phase. I may have to do some timing tweaks, as the phantom center perceived did move a bit. Already accounted for that drifting with some SPL tweaks but some timing difference might help too.

I'll go into listening mode again, playing random tracks.

Make that no listening today . I forgot I had a broken tile on my roof and decided it was more important to fix that. A mild storm earlier this week caused that. While I was up the ladder I thought it would be best to start cleaning the gutters etc...

There's always a next time...

Out of phase channels can do some funny effects - like widening the image or even throwing sound behind you. Of course it can be bad for the bass and the phantom center, but on surround it could be fun.
Let us know what you think.

To be honest, I'll need time.
The ambient has always been a rather out of phase mix, as it consists of (L-R) and (R-L). The biggest change is the phantom part in this setup. It is timed rather late so it won't eat away bass from the mains. If anything, it "could" influence front to back balance a bit more. Not by SPL but out of phase phantom material will be in phase from behind and vice versa.

I remembered Lycan (werewolf on DIYaudio) mention it as an option for the ambient channels from reading it way back when on diymobileaudio. I had tried it very early on, but this was without adding/mixing in phantom material.

The experiment was short lived. I just had to conclude the former setup did way better. After changing it back I couldn't stop listening...

Even if something somehow "gets" you the first time, it may not withstand the test of time.

It turns out my shift in phantom center wasn't due to the ambient setup. After turning off the ambient channels it was still there. Even when I tried older corrections, they all showed the same deviation. I have not found the reason, it doesn't seem to come from any settings on the PC. Stuff like that really is no fun. What else is there, the DAC, the amplifier and the speakers... I first noticed that shift during the Top 2000 listening, my girlfriend was sitting next to me so I thought, that must be it. I did find it strange that it didn't happen like this before with multiple people listening.
Is my amp playing tricks on me?
