SES file extension is related to the Audio project created by Adobe Audition, a sound production application. SES files were originally used by Syntrillium Software's Cool Edit Pro, which was acquired by Adobe and was rebranded as Adobe Audition and the first version of Adobe Audition was released in 2003. Adobe Audition allows users to record, mix, edit and master audio files from a recording session. It can include multiple tracks and the mixing settings for each track. It comprises references to an audio file but does not store the audio data similar to a playlist file. For this reason, SES files cannot be used unless the associated files are also available.
