With the release of Audition 3.0, a new multitrack XML session format was implemented. XML is a human-readable standard for electronically encoding documents with numerous benefits over binary formats which have been well documented. XML is the foundation for documents that determine how this web page will appear in your web browser or how your word processing application displays the formatting and fonts used in your last .docx file. It has become a crucial standard for archival and project formats because of it’s high-readability and platform compatibility.
The Audition team recognized the need for a safer archival format, one that could be reconstructed if the file were partially damaged or that would ease conversion to other DAW formats. Audition XML sessions can be opened and edited in Notepad, created programmatically from scripts and other tools or even printed on paper for physical archival. Thirty years from now when Audition has been updated to support the latest in 5th dimensional sound and neural input devices the original session parameters could be accurately reconstructed from the XML document.
You can save your sessions in the new format by changing the “Save as Type” option in the Save Session dialog to “XML (*.xml).” You can also open and re-save any legacy Audition sessions that are in the binary .SES format as XML to ensure compatibility with future versions of Audition. Just open your original session and go to File > Save Session As and select “*.xml.” The new XML session can be saved alongside the original .SES file.
