I am confused, one minute I am being told it will not be notable, the next that is will "change the pitch and the tonality of the voices and music. ".    This is kind of what my googeling also seemed to reveal.  There seem to be two camps;(.

Not really ;-)

Resampling is no problem to do in good quality, but it leaves the sound with a 25/24 pitch change. If you also want to pitch-correct the resampled audio, you need a higher quality approach. However, a small change like the one needed for 24/25 is usually unnoticeable. It get's more complicated with larger pitch changes, and typically you would want to resort to external tools using special algorithms. Music is typically more complicated to pitch correct than dialog.

Did you ever notice strange audio, pitched audio, etc. on any cinema presentations, DVDs, BluRays, etc.? No? Then you shouldn't care, because this technique is used widely for most entertainment content. As you are living in europe, which is a 25/50Hz country, you will be exposed to this every day when watching/listening entertainment media, at home or in cinema.

As you have your audio in separate files, you could play with it easily using external tools like Audacity, Audition, etc.

Always trust your own eyes and ears. 

The best way, of course, is to produce in 24fps/48KHz right away if aimed for cinema.
