Dear PD-ers,

We are working on an installation with 4 machines running PD to feed 157 loudspeakers. We are interested in reducing latency to a minimum between channels, and especially between machines. The inter-channel latency in less than a sample, so all is fine there. For inter-machine latency, we arrive at differences on the order of 10msec, close to our minimum audio-buffer length of 11msec. Any small audio-buffer and we get audio artifacts.

We are using a word clock synchronizer (Nanosyncs HD; Rosendahl), but I don't think that does latency synchronization.

My question, is there another means to improve inter-machine latency performance other than reducing the audio-buffer?
