I did a little bit of looking around this fall, but did not find much. There are of course the normal streaming solutions, like Icecast, which seem to work well, but has to large a latency for my purposes (distributed music playing). What I ended up with was writing my own. (Currently with assistance from Lee Revell.) It has not come very far, but I am able to stream music from one computer to another. It also deals with transmission problems (lost/duplicate/out of order/late packets) and drift adjustment. I have plans to release it in the not to distant future. See <URL: http://www.q2s.ntnu.no/~asbjs/ldas/ldas.html > for more information. Then there is jack.udp, which I discovered half a year after starting my work. This seems like a good tool. It streams jack data between two jackds running on different computers. There are a couple of reasons I didn't switch to jack.udp myself. As far as I have understood (and I may well have misunderstood), jack.udp does not do drift adjustment, so it will have synchronisation problems if you want to use it between two computers with un-synched soundcard clocks driving jackd. It will work well if one of the jackds is a "slave" jackd, though. (Somebody please correct me if I'm wrong here.) Also, the jack format keeps samples as 32bit floats. Although I do not care that much for bandwidth issues, I found that doing away with half of this, using 16 bit PCM, was valuable when transmitting over the Internet in general. Asbjørn
