I was sitting in on an ADR session for a television show at an ADR stage the other day and I was talking to the ADR mixer about how Sound Design is different for TV than it is for Movies.

He told me one of the main differences was that sound designers usually use pre-made scene effects, for example, a crime scene.

For a crime scene, you've got a police-car walkie talkie going, an ambulance siren, people murmering (detectives), some ADR callouts from the forensic team, city ambience or rural ambience, etc. etc. etc.

He said what they do is keep a pre-made pack of sounds like this and then just plop them in on the scene and move the individual sounds around so they fit.

Does anyone else do this?

I personally like to be original and re-create a scene from scratch as I see fit for each project, but do you think it has some benefit to create pre-made scenes to have in your library for some type of project you work on a lot? Especially when you've got a tight deadline like on a TV show or series?
