This sounds interesting. Even has things like rod clank and water stop sounds for steam and lots of stuff for diesels too. DCC or DC. Maybe QSI sound got some competition going. Wonder what it will cost? Bruce

Tsu ·na ·mi (tsoo-nä´-me) n. A huge wave of sound caused by SoundTraxx's newest and slightly unpronounceable product! The Tsunami sound system is SoundTraxx's new high-performance, onboard locomotive sound system. Like the DSD-150 it replaces, Tsunami integrates a full-featured sound system, four Hyperlight lighting effects, a motor controller and a DCC decoder into a single, integrated package and is compatible with the NMRA DCC standards and Recommended Practices. Unlike the DSD-150, the Tsunami sound system can also be used on 'Analog' layouts and controlled with a conventional power pack, hence its model designation now begins with DSS rather than DSD.
At Tsunami's core is a true 16-bit Digital Signal Processor, or DSP, capable of executing over 40 million instructions per second. With this new level of performance, SoundTraxx was able to give Tsunami 14 functions, over 22 individual sounds, and 4 special effects including the ability to alter the exhaust sound automatically in response to changes in the engine load. The motor controller received numerous enhancements as well, including the use of high frequency PWM and back-EMF based load compensation. To keep the size down, only components available in highly miniaturized packages were selected for use in the Tsunami resulting in a form factor that measures almost 30% shorter and 50% thinner than the DSD-150.
