Ay,ay,ay...

4 convincing the brain that the vocals comes from both ends of the stereo field the L+R signals MUST b significantly different from 1 another.

The more they r identical the more the brain interprets the sound as mono due 2 symmetry.

Best results r achieved by recording the part twice.

The second best alternative:

Duplicate ur track, pan both trax left and right, strip a 15 ms delay across the right channel.

That's ur starting point. increase the delay time, modul8 it, add a slight pitch shifter or chorus etc, anything 2 make the 2 tracks different in waveform @ any given time.

Er... That is if U have the per4mer @ ur command...
