How to tweak Nebula Reverb to run at very low latency?

Postby sfunk » Wed Nov 17, 2010 10:10 pm

I noticed on another forum a poster noted that Neb Reverb can be tweaked (i assume in the xml) to run at a lower latency. There was a debate whether this could be lowered and have it running of multiple cores. I running the mac Au version. Is this possible?

Go into the Nebula master page and change the DSP buffer size

if i think right, then the shorter you set the DSP buffer the shorter maximum reverb time you get.

The DSP buffer has nothing to do with the Reverb time but lowering the buffer will mean more cpu usage.

Nebula F.A.Q.
http://www.acustica-audio.com/forum/ind ... =viewtopic

Q.5.6 When I load up an instance of Nebula (reverb .DLL version) it puts my track out of sync with all others, even if I check the little box called "plug-in delay compensation".
Some versions of VST hosts have plug-in delay compensation active only on inserts.

Reverb plug-in have a big buffer and some sequencers cannot compensate. Plug-in delay compensation will not work unless you change the amount of buffer inside Nebula. Setting the Nebula Reverb engine DSP BUFFER parameter to 8192 will result in a real latency of 8214 samples or 0186.4 ms at the 44100 Hz of sample rate.

If you DAW is powerful enough you can decrease the amount of DSP buffer in Nebula Reverb .DLL plug-in to place it in the range of compensation is able to work.
