File type specification:
The mt9 file extension was used for an audio format developed by Electronics and Telecommunications Research Institute and was commercially used by Audizen.
The format was an attempt to replace MP3 format in Audizen programs and devices. It has separate controls on the sound volume for each musical instrument, such as guitar, drum, base and voice and has the ability to package entire albums into a single file.
This mt9 file type entry was marked as obsolete and no longer supported file format.
This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
