Recently I've been working with the transport synchronization capabilities of the JACK audio server. This article is a report on those capabilities as tested with a variety of Linux audio applications under the JAD and 64 Studio distributions.
By now everyone in the Linux music and sound world has heard about Paul Davis's JACK audio server and transport control system. By way of introducing this article and for the benefit of the remaining few people who don't yet know about it I'll briefly review JACK's more salient characteristics.
JACK's name is a recursive acronym for "JACK audio connection kit". The kit provides a system for freely connecting independent audio data I/O points, thus allowing the audio output from one JACK-savvy application to be sent to the audio input of any other JACK-aware client. The system supports multiple connections to and from any audio I/O points, and all data streams are synchronized to sample-accuracy.
