Synthetic. Look at the repeating form. I back my vocals with a sample too. I don't know what they are doing to make it.

It sounds like an Automatic Double Tracking plugin.

Maybe even this one:

ADT by vacuumsound - Artificial Double Tracking VST Plugin and Audio Units Plugin - KVR Audio Plugins

That sounds close.

Looking at the VST, they add a waveform to the signal. Ingenious.
