Sound/Demo1
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

30REM Demo of how to add a new voice generator
40REM Mostly copyright Acorn (see PRM 4.74-4.76)
50REM
60REM NB Strongly recommend you connect the headphone socket
70REM on the computer to a hi-fi amplifier or at the very
80REM least to a pair of headphones.
90REM The computer's own internal speaker/s are poor, quiet
100REM and don't reproduce low frequency sounds well.
