yes, I did write that. But Miller implemented a binary transfer from pd to pd~ so the native solution must be lot's more efficient now. I did not test if shmem is still faster.

Yes, using shmem_send~ and shmem_receive~ will add 1 more block latency on top of pd~ latency.

cheers

> @cyrille, i have another question if i may, i saw somewhere in the list that you write that streaming audio from pd to a subprocess with shmem is much more efficient in terms of cpu usage, is it still the case? also if i understand correctly from the docs i will then have latency of one block size + fifo right?
