Re: More basic audio effects with premiere :)

I'm not sure that a slap echo with a 3-frame travel time will really convey the accoustic space of an empty flat.

A combination of reverb processing and subtle EQing would be the simplest in-studio method of adding perspective to dry ADR. Of course, your success will largely depend on the quality of your reverb plugin. Cheap reverb algorhythms tend to draw attention to themselves, so consider investing in a good impulse reverb plugin.

"Worldizing" (ie. re-recording the ADR played back in an accoustically live space) is another option, although you'll need a very accurate playback and recording combination to avoid your tracks sounding like they were re-recorded. Worldizing is generally better suited to those situations where the colouration of the playback system is a part of the desired sound (eg. car stereos, telephones, PA systems).

Its unfortunate that ADR is rarely recorded with appropriate accoustic perspective.
