Hi Andrew,

this is simple: Yes, you can.

Just override AUBase::GetLatency(). - It returns a 64bit float with Latency in seconds, not samples.

Oh... uhm... I think you also have to override AUBase:: SupportsTail () and return true here.

Cheers,

;) Urs

Hi! I'm wondering if the AudioUnit spec allows plugins to "look ahead", compensating for latency caused by DSP. My plugin needs to read a short amount of audio prior to "knowing" how to act on it. The problem is, if it were being used in a sequencer (like Logic), the output would lag behind the rest of music. I've seen latency compensation and "look-ahead" features on some of Emagic's processors (such as the new Sound Designer reverb unit), but these aren't AudioUnits.
Can I do this? And if so, how?

Thanks,

Andrew
