I'm looking for information on synchronizing the audio on multiple

computers running max. This would have to be sample-accurate

synchronization. Is there a way of doing this? I suspect there is not,

This should not be a problem at all, you need either soundcards with a 

wordclock (ment for exactly that purpose) or just connect some 

audiochannels digitally and have all but one be slaves to the digital input.

Most cards do have extra spdif connectors, you can use those to clock 

This has also the advantage to be able to send your custom sync signals 

to each computer along these connections. You might have to calculate 

the latency correctly, but thats always a constant number of samples.

another way is Open Sound Control (OSC). this is something like midi but

then 21387286 times better with more possibillities in diffirent messages

including audio. the lemur is based on it for example.

connenct two computers in a network, set the ip-adress, and it should work.

well, its a bit more complicated but you can find objects and helpfiles for

That sounds good - but how would one calculate the latency correctly?

There is the DSP status window. You set the buffersize there in samples, 

and then there is a sampling rate... But we are in Max land there must

There is the DSP status window. You set the buffersize there in samples, 
and then there is a sampling rate... But we are in Max land there must 
be a way to patch it:
