Re: Audiounit I/O Buffer Size



Hi Bill

Having this property would really help us getting the most out of the hardware en the host software.
We have thought indeed about this UI item, but for now we prefer to not bother the user too much with difficult to understand preferences. We will reconsider it, but having this property would invalidate that discussion.


Thanks,

That's an interesting point...

We could add a new property (something like I/O Buffer Size), but don't have anything currently. Only thing I can think of is to have something in your UI to let the user chose what they'd like to operate with.

Hi

I wish I could get hold of the Hardware buffer size from within a audio unit. I know I should not be dependen on this and that I should use de GetMaxFramesPerSlice to setup my buffers.
But.... I would really like this value so I can minimize the latency of my plugin. Since I use convolution in my audiounit, I always have to optimize between latency en CPU heaviness.


I would like to implement some buffer size adapting internally to the plugin (like I did for RTAS) to make sure that the plugin performs in the best way I can imagine. So when the track of the audiounit switches to be "live" it performs with lowest latency that makes sense. The only value I really would to get a hold of is the I/O buffer size as set in the preferences panel of Logic.
