Are you trying to do this in a single DSP tick? This would create a CPU
spike and lead to audio dropouts, depending on the value of "delay" in
the audio settings.
You can either
a) increase "delay" -> more latency -> more chance to "absorb" CPU
spikes, or
b) spread the operation across several DSP ticks.

so i tested it with linux and it works great, my only problem right
now is that i get an audible glitch when i setmem /dumpmem on
a 5760000 samples size buffer, i tried breaking the setting / dumping
to smaller chunks but it only got worse, is there any workaround?
thanks!

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.

> @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?

experimenting with shmem (the latest one i could find in deken),
it works fine as long as i use very small arrays, as soon as i try
to use bigger arrays ( havent checked where the breakpoint is but
more than approx 400000) it doesnt and it returns "could not
allocate shmem memory Id"
