Sub-frame editing necessary for casual audio syncing?

Well, I'm back again. Really glad I found this website. :D

So, the problem is that I've found out about sub-frame editing and how important it can be when syncing audio to video. I'm using free editing software (lightworks) and am not really ready to shell out the money for any editor capable of this or any specialized audio syncing software like plural eyes or dreamsync.

BUT:

I've gotten the impression from my research that sub-frame editing isn't really necessary unless you're doing something with music (I don't know what exactly). Therefore, my question(s?) (finally) is: do you really need to have sub-frame capability when you're just syncing ye-olde typical audio to video; when is sub-frame editing absolutely necessary; and if I do need to be able to edit sub-frame-idly, is there any free software out there capable of it?

Most people can't tell if the audio sync is out if you are within one frame of the correct sync, so I would not worry about this.

The only time I've had issues with sub-frame sync is when you're trying to mix multiple audio recordings that do not have frame accurate sync, so you end up favoring one recording over another because you can't get perfect sync with all of the audio tracks mixed together.

Premiere can also do it, if you have access to that. If you right click on the timeline window you can select "Show Audio Time Units" which allows you to zoom WAY more than single frames, way on down to where the waveform almost flattens. I've used this a number of times with issues like Guy discusses.

Thanks, but I can't use premiere right now due to money. I'll keep it in mind when I eventually get to that point, though.
