i tried to extend the streamin~/-out~ objects to send more than one signal
at the time (e.g. streamout~ otherhost 1234 8) for 8 streams/ 8 inlets in
one object, and dropped the extra format information (only 16bit then)
which produced a seperate udp-packet for every block. the result was
better, but still not perfect.
maybe sending every 4th block or so would increase the performance again.
still trying
DITHER
