There are various formats for exchanging the editing data from AVID or Premiere for the sound editing program:
The Material eXchange Format (MXF) is a file format for broadcast video files. It is a subset of the Advanced Authoring Format (AAF) and was defined with the aim of simplifying the exchange of audio-visual files (including metadata).
The Advanced Authoring Format (AAF) is a file format for storing multimedia data. A complete project (“composition”) is stored in an AAF file, both the media content and metadata. Volumes, fade curves and clip names are also exported.
Open Media Framework (OMF) or Open Media Framework Interchange (OMFI) is a platform-independent file format intended for the exchange of digital media between different software applications. It is used by programs such as Final Cut Pro, Adobe Premiere, Sonar, Nuendo, Cubase or Logic Pro.
