[ULTRAaudio]Audiophile Music Servers an Interview with Matan Arazi

MA: The design of any modern desktop operating system is not ideal for a music server or other real-time devices. This is the reason why many medical, aviation, and aerospace computers use dedicated, minimalistic, real-time operating systems. In a desktop computer, the operating system must handle the screen, the keyboard, the mouse, various applications, etc., all while maintaining the stability of the entire system. This is very useful for a general-purpose computer such as a Windows PC or Mac, but comes at a price.

In contrast, real-time operating systems such as VxWorks, or specialized versions of Linux, can afford to shed many of these safeguards and functionality because they serve dedicated purposes and operate within tightly controlled parameters, and thus can push the envelope.

Although it's written in as an interview, I found the article to be extremely informative. After reading it though, I feel the need to build a dedicated music server using a linux based OS like mentioned. devil-smiley-019.gif: But maybe without all the aerospace technology described haha.

Edit: Added :facepalm: Thanks Square

What a load of BS marketing. All you need to do to eliminate jitter is to buffer the output - something that sound cards have been doing for decades now. And if your DAC is separate from your source then all the EMI in the world (at the source) is irrelevant as long as the signal remains intact.

And a real-time OS? Again, completely non-beneficial. Saying that an OS is "real time" refers to it's processing scheduler and memory allocation, and means that every time you run a program it will have the same performance, no matter what else is going on. If all you're doing is playing music, which takes up 1/2 of 1/2 of a percentage of today's CPU power, there's no reason for it. It's only the output stage that needs a good timer, which has very little to do with the OS.
