Description

Ambiances are background recordings of places used in audiovisual productions to make listeners feel they are in places like a pub or a farm. Accessing to commercially available atmosphere libraries is a convenient alternative to sending teams to record ambiances yet they limit the creation in different ways. First, they are already mixed, which reduces the flexibility to add, remove sounds or change the panning. Secondly the number of ambient libraries is limited. We propose a semi-automatic system for ambient generation. The system creates ambiances on demand given textual queries by fetching relevant sounds from a big sound effect database and delivering them into a sequencer multitrack project. Ambiances of diverse nature can be created easily. Controls are offered to the user to further specify its needs.
