UNVEIL
CPU Load optimization
UNVEIL uses a lot of CPU. The mathematics involved are highly complex, so there’s a lot of
computation to be done. However, CPU load is affected by a couple of variables. We’ll outline
strategies to get the most out of UNVEIL on your CPU here.
1) Use large buffer sizes. UNVEIL needs to look at a certain amount of signal to be able to
discern what is reverb and what isn’t. If your buffers are set to values that are shorter than
that, CPU load increases significantly. UNVEIL internally operates on a buffer size of 4096
samples, so in most host applications, you’ll want to set the buffer size to the highest
possible value. We recommend *at least* 1024 samples.
2) In ProTools, use multi-mono instances if possible. ProTools can compute the channels of
a multi-mono instance on separate CPU cores, which distributes the CPU load more evenly
and allows larger channel counts than when running a multi-channel instance on just one
core.
3) In Logic Pro, all plug-in that are inserted on a bus, output or aux strip that is fed by a live
input source - such as a live input or a virtual instrument track set to record enabled - are
rendered on one core. This may result in CPU overload messages even while all except one
core are idling. Try changing the routing or disabling any record enable switches on virtual
instrument tracks.
4) Use the mono/stereo version of the VST plug-in whenever you do not explicitly need more
than one or two channels.
5) Closing the plug-in GUI saves some CPU cycles, too.
