Does the shape of a lightning bolt have an effect on the sound of the thunder?

Primarily if we were to graph a bolt of lightning and compare it the the levels recorded to that associated roll of thunder, would we see a correlation?

What if the sound were graphed in a 3D space? How different is a forked lighting bolts' thunder VS the thunder from a bolt with no forks?

Does this make sense?

The jagged and irregular shape of a lightning bolt is one thing that causes thunder to rumble. Different points all along the lightning bolt are different distances from your ears and thus the sounds arrives at slightly different times. If a lightning bolt were perfectly straight, for example, you'd hear a big boom but it would be uniform in intensity for its duration (discounting effects of distance on sound intensity). 

A forked bolt would make a sort of ka-boom sound as the two separate forks of the bolt create sound waves that arrive close to each other but not at the exact same time (at least in most cases, you could prove mathematically that at a point equally spaced from each fork, the sounds would constructively interfere to create a louder boom, however it's pretty unlikely that you'd happen to be in the exact spot where this happens).
