increase audio buffer size?
Le 10/02/2020 à 12:38, iftah gabbai a écrit :
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!

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 Le 01/02/2020 à 10:32, iftah gabbai a écrit : > @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? > > On Sat 1.
