No rim is 100% perfect to start out with so there will always be differences in spoke tension, especially near the joint and on the opposite side of the joint. In an ideal world, every spoke with the same length would have the same tension.
Truing by ear gets you nothing more than squeezing pairs of spokes by hand does.
+1 on radial + lateral.Any other "off key" method could cause failure,and mash your nuts on the crossbar.
