Interesting stuff
I haven't even begun thinking about delay or partial phase-shifting like this as a "processing artifact" itself not in the digital domain...

The amount of db for an antialiasing filter depends on the application and the desired level of filtering. Generally, a 20-40 dB filter is used in most audio applications.

Thanks ! i did not see your response before now. I will make filter with less weight !
It's true that even with 20 db i could not very hear the aliasing.
