Sorry, I could not resist the off-topic.

As far as I understand, CP/M copied the file name conventions (except 
subdirectories and file versions) from Digital VAX/VMS, which was 
supposed to replace the archaic *nix systems. If OpenVMS did not die in 
the hands of HP yet, theoretically it could still win. :-) BTW, VMS 
distinguished binary and ASCII files, too. AFAIR, CP/M does not really 
distinguish them, but it does not store exact file lengths either. You 
will only know how many blocks the file is, not how many bytes.

I guess it would be somewhat funny if you ported the sound to Commodore 
128 CP/M, or maybe even the Commodore 64 CP/M. The latter would probably 
be a hardware challenge too. In later editions of the Commodore 64 
Programmer's Reference Guide, the pages about the CP/M cartridge were 
made blank.
