Has Bane's Voice Been "Cleaned Up" For Digital Releases?

Anyone know?

I remember watching this in the cinema and in pretty much every scene he was in, it was like wtf is this guy saying?!!

I remember turning to the person I was with and asking, to get a shrug of the shoulders reply. As I cast my eyes around the cinema, it seemed clear I wasn't the only one as I saw literally other people doing the same thing.

Afterwards I looked online and there was a lot of stuff about this muffled voice and how it was terrible trying to understand what he was saying (alongside the usual comments about how the end was impossible for him to have survived and he clearly must have died).

But anyway, some clip popped up on my youtube the other day, and I thought I'd give it a watch (despite not really being a fan of this, the worst of the Batman cinematic releases) and low and behold, I could make out what he was saying no problem at all!

So what's happened? Has his voice been cleaned up? Or was this just a problem in cinemas due to their sound systems?
