What is a BMML file?

Braille Music Markup Language File

The .bmml file extension is used for a source code and script file format that was developed to provide blind users with access to musical notation data. Also known as Braille Music Markup Language files, these BMML files store musical notation details in Braille characters and symbols. Through the Braille Music Reader, which was developed by Contrapunctus, these .bmml files can be viewed through the use of Braille devices like refreshable Braille display monitors.

Braille printing devices can also be used to print out these BMML files through the Braille viewer applications that are bundled with the Braille printers. Third-party Braille software products that can support the .bmml file format may also be used to print out these BMML files. The Braille Music Reader software can be used to open and view the content of these .bmml files. Other Braille programs can be used to edit the content of these BMML files.
