Pro audio research & development
Christian's day-job at JOYNED GmbH and previously 28 years at TC Electronic has brought insight into pro audio technologies like clocking and analog and digital audio interfaces. Articles below dive into these subjects.
Discussion of intrinsic jitter, interface jitter, jitter rejection, and clock design as implemented in TC Electronic System 6000.

Network-based audio systems pose a significant jitter problem when AD, DA and sample rate conversion is required. This paper describes a new clocking technology that eliminates such obstacles, and finally makes Firewire as robust as a high-quality point to point digital interfacing.
