SimPhonics Audio Systems

Over the past 14 years since SimPhonics introduced the first digital audio system for flight simulation, the technology has changed considerably.  A primary goals continues to be the incorporation of the latest technology to aid our customer OEM's to integrate SimPhonics products into existing and new devices.  

Originally, dynamic digital audio was the domain of the Digital Signal Processor.  SimPhonics legacy systems were based on the use of the PC as a host and the DSP as the primary source of digital audio.  The PC controlled the generation of digital audio on the DSP, but the DSP created the digital audio samples. 

That has changed.  PC CPU's are now more than powerful enough to create and manipulate streams of digital audio.  More importantly, standards are now emerging, created by necessity in the commercial market, that are finding their way into high end applications.  The hardware platform of choice is now clearly the PC.

SimPhonics has embraced this new trend with the introduction of the FXDirect and SMx digital audio systems.  Generation of audio is performed on the PC CPU, while the DSP is now focused on low latency mixing of digital I/O streams.  This means lower costs, higher performance, etc.
