Roxio Sound Editor project
File type: Audio and sound file
A dmse file is a project file created by Roxio Sound Editor, an audio-editing component of Roxio Creator NXT.
It contains project data, including references to audio files and the edits applied to them, rather than a standalone audio recording.

The dmse file extension is associated with Roxio Sound Editor, which is included with Roxio Creator. The software is part of Roxio Creator NXT for Microsoft Windows.
A dmse file stores information needed to continue an audio-editing project. This can include references to source audio files, audio edits, and transitions. The source recordings may remain separate from the project file.
The format is intended for use within Roxio Sound Editor rather than for exchanging finished audio between different applications. It remains tied to the Roxio Creator software family.
Open a dmse file with Roxio Sound Editor in Roxio Creator NXT on Microsoft Windows. The source audio files referenced by the project may also be required, especially if they have been moved since the project was saved.
A dmse project is not itself a standard audio recording, so it is not normally converted directly. Open it in Roxio Sound Editor and export the edited project as a supported audio format to create a standalone audio file.
