Codisk Audio File
From Just Solve the File Format Problem
The Codisk Audio File format was used in the 1990's for high quality compressed and uncompressed audio by radio automation software "CompuRadio". Recording and playing the files required installation of an advanced audio card (of unknown origin).
CompuRadio runs on MS-DOS and was developed in an advanced (unknown) version of QBASIC. The software was created by the Belgian company Van Rompaey - Devaro bvba, which was renamed Futurex.
