David Dwyer Thiel Sound System (or DDTSS for short) is a official name of a sound program originally created by David Thiel for Action Graphics in 1983 when making C64 games, and Leif Marwede ported over DDTSS to the NES when making American Gladiators, for developer Incredible Technologies.

It is suspected that Marwede wrote the music, either in assembly language, or a utility to convert MIDI files into his sound driver.

The driver outputs to the 2A03. For music, it uses both square wave, the triangle, noise channels and DPCM channel.
