Mac OS X: Increase I/O Vector Size beyond 2048?
Sep 06 2012 | 9:10 pm
Hey, so I am writing an external for Max that involves sound localization. The method I'm using benefits from a large sample frame size. I would prefer something around 4096 or even up to 8192 would be awesome. The problem is that the Core Audio driver in the Audio Status window only shows up to a 2048 I/O Vector Size. Does anybody have any clues as to what's going on and if there is any way to get what I want from this setup?
Hardware details:
Computer is a 2008 MBP running Mountain Lion.
Audio Interface is a Saffire Pro 40 connected to my computer through Firewire.

Send the poly~ a "vs 8192" message and do your magic within that... In case fft is involved in your external, I would create it to be used inside a pfft~. There you can set higher sizes as well...Stefan
