Need sound decoder for P1k C-Liner

Anyone know of a sound decoder for a Proto 1000 C-Liner?

Sountraxx Tsunami TSU-1000 Fairbanks Morse with a 20x40mm Rectangular speaker/baffle. If you can find a high bass speaker to fit, it will sound better as well. Keep in mind that you NEED a baffle as this sound file has a tonne of bass in it.

The QSI Revolution lists a FM sound scheme, but it is inferior to the Tsunami.
