What is a SESX file?

An SESX file contains a session created by Adobe Audition, an audio production application. It stores a multitrack audio project in an XML format, which includes mixing and effects settings. SESX files do not contain the actual audio data in a project. Instead, they save the pathnames to the audio files.

You can also import many different types of audio formats into the projects, such as .AIF, .FLAC, .AAC, .OGG, .WAV, .OMF, and .MP3. To import an audio file in Audition, select File → Import.
