Differences in audio mixing across various releases

[TheRed259]

I’ve noticed certain differences in audio mixing in the French dub of some Dragon Ball Z movies.

These differences are particularly numerous and noticeable in Dragon Ball Z: Le Film (Fusion Reborn & Wrath of the Dragon). For instance, Shenron appears with 3 different voice filters across the various releases and Goku appears with or without an echo while in some cases his reactions and screams remain in Japanese but in others they are heard in French. Gotenks also appears with or without voice filters, among many other examples you can see in the video below...

Have you noticed anything similar elsewhere? It should be noted that I am not talking about music changes or re-dubs.

I don't believe Android 19 and Super Buu were redubbed in the remastered Funimation dub, but they both had voice filters in the original 1999-2003 dub.

Oh yes, you're right.

And apparently there are other similar cases such as:

Oof... so looks like the English dub ISN'T alone in being constantly tampered with from release to release.

One of the best things in DB is the music. The fact that the original score was replaced on the English version is definitely a phenomenon I can't fully understand yet. In Mexican dub the original background music was maintained. I understand the English spoken fandom is somehow divided in opinions. I apologize, again, I don't know much but wiling to learn, hence I am here. Peace.

It would certainly be an interesting thing to track when exactly licensing concerns stopped being a problem, especially in a place like the US.
By this point in time they probably never were, but some exceptions were select insert songs that Toei charged extra to feature which led to them being missing even on international versions that otherwise contained the original score.

But on the whole there's not that much to wrap one's head around; Toei quite simply never cared what happened to its properties that went on TV in the US, it's even to the point where 2 different score projects by the same composer under the company both got replaced by 2 different adaptation companies (which weren't even Funimation).
