Is there a difference between having two audio sources going directly into an object and using an additive object.

Essentially something like this:

|output1~| |output~2|
|                  |
| _______ /
|/
|*~ 1|

As opposed to:

|output1~| |output~2|
|                  |
|               /
|          /
|       /
|+~ 1|

Another way to explain this:

If you take two outputs put them in the left inlet in an object: |*~ 1|, that would be the same as one audio output into the left output and a second audio output into the right output of this object: |+~|

Hopefully this can should what I am trying to ask about. I do not think there is any difference between these two ways but want to be sure I am not missing something.

@raynovich I could be wrong, but I remember reading that hot (left) inlets always perform a summing operation. Anyway, I have been doing both for a while with, as you say, no noticeable difference.
You could try summing a couple of sines by both methods..... and plotting the output.

@whale-av RIght!

Yes, I should do that to see if there is a difference, but I doubt it would be noticeable.
