Hello.
I'd like to know your opinion:
what's he treatment with James Warren voice in this song?

Thank U.

The forerunner to Autotune. Manual pitch.

Manual pitch?
Do you want to say Eventide harmonizer, delay modulation?

I have no idea. Maybe double tracking or some modulated delay.

Okay I gave it a closer listen and it sounds like a gentle flange / chorus with a haas effect so it has a panned feeling. I'm not sure what box they would have used.
It would probably have been Eventide or something similar.
It doesn't sound double tracked.

Really, I should be answering questions where I am a specialist.

Thank you very much for your help.
I was asking you about a FCS P4S ME, finally I've got a P3EXM the monster.
Best regards from Spain

How is the P3EXM because the P4S was great but quite subtle for mastering?

I suppose it can be harder.

Oooh that looks mean!
