SMx Digital Audio System

Once again, SimPhonics extends the state of the art in simulation audio systems. The SMx delivers up to 64 channels of streaming audio in a single system.  As with our FX-30 system, both Sound and Communications functions are performed in a single system; however any SMx channel can be used for ANY function. A 16 channel SMx system requires only a small 4U space, and 32 channels fit within an 8U space.

All of this is completely programmable via V+, a visual programming language that is self documenting and easy to use.  Build your application from existing samples, or we can build it for you.   

Tired of buying a system and finding out later it is limited?  The SMx system comes with everything from DIS to a full sound simulation system with terrain server in a single package for a single price.  Use all of the sounds and radios you need now and in the future at no added costs. 

Years of development of new hardware and software has produced a system that is capable of anything you will encounter for simulation audio in a single system.  And, it costs less.
