I searched for a question like this and didn't find it here; but if so, please direct me to the link.
I am trying to understand why - (maybe as a cliché?) - so many many times when in a film there is the intent to show something that belongs to the past, and the visual itself cannot immediately convey this, the dialogue / voices are usually processed in similar ways? Is it merely because with reverberation long tails we may associate distance to it? Or are we just so used to it that we just don't think about it any more and assimilate?
Do you know any examples that convey this in other way than that?
Looking forward for your answers! Thank you!
