Soundjack

by Dr. Alexander Carot

Since the year 2005 the Soundjack software has been the result of Alexander Carot's musical experience and research activities in distributed music on the Internet. Once you are familiar with a few basic pinciples related to audio streaming on the Internet it will provide you the best possible quality- and delay conditions in order to play live music as shown in the videos below. However, you need to realize that the final latency depends on the physical distance, network capacities, the actual network conditions and the actual routing between the involved peers. In most cases real musical interaction is limited to physical distances below 1.000 km. It is important to understand that latency acceptance thresholds vary from player to player and furthermore decrease with an increased performance tempo. Altogether the objective judgement about the feasibility underlies a complex process. In that context Carot recommends reading the papers below or his final thesis here.

Soundjack has been optimzed for OSX usage, however a Windows beta version and a Linux experimental compilation already exist.
For further information do not hesitate to contact the author via email or meet him in the Soundjack chat below.

Chat system

In order to establish a successful Soundjack audio streaming connection you currently need to know the IP address and respective port (if 4401 doesn't work) of your remote partner(s). In that context you can use the following Soundjack chat, which will make communication easier for you:
