[Sir Nose]

panning

or

maybe a ping-pong effect

[ninja6485]

the korg radias has an effect called rotary, which wirls the sound arround from left to right as though it were spinning arround you, or like a constant left to right wobble.

An Auto Pan effect, or some Delay effects that can have dif left and right times can sort of do too, or one of my favs which is a Slice effect with different pan types.

It depends on the effect...

If the sound repeats like an echo, going left, right, left right until it fades away, that's a ping-pong delay (example: tambourine sound in "Drive" by The Cars).

If it pans smoothly left to right and back (like a lot of EP/vibraphone sounds in the 70s and 80s), that is an auto-pan effect (example: "Babe" by Styx).

If there's some pitch shifting/phasing going on along with the panning (commonly used on organ sounds), that's a rotary speaker effect, also called a Leslie effect since it emulates the Leslie rotary speaker systems often used on Hammond and other organs. (many examples, Steppenwolf's "Born To Be Wild" comes readily to mind)

[cornutt]

Good points. One thing to add is that a rotary speaker might or might not have any left-right motion, depending on how they miked it up when it was recorded.

Also the beginning of Pink Floyd's Us And Them.

The piano intro to "Echoes" was also run through a Leslie.
