An OMF file is an audio file saved in a standard audio/video format based on the Open Media Framework Interchange (OMFI), a standardized interchange file format. It may be exported from digital video editing or audio workstation (DAW) software and is commonly used to share project data between multiple applications.

An audio project saved in the OMF format can store multiple audio tracks, volume and pan information, and references to audio files. However, not all settings, such as insertion effects and channel routing options, may be saved in an OMF file. Therefore, not all project and track settings may be transferred when opening an OMF file in another application.
